5 ii KOROSI SPECINDO INTRODUCTION 1. Philosophy of Corrosion Monitoring, Inspection and Control Corrosion is known as the degradation process of a material caused by environmental conditions where the material is in operation. Since corrosion is a natural phenomenon which would lead to economic lost, environmental damage and safety threat, it is one of major considerations in asset management and maintenance program. Corrosion monitoring and inspection are invaluable tools for assisting the asset management and maintenance program because corrosion monitoring enables detection of presence of corrosive substances and quantitative estimation of corrosion rate and prediction of remaining lifetime of an asset. In contrast, corrosion inspection allows access on the actual progress of corrosion. Furthermore, in a facility where corrosion monitoring and inspection are already practiced, the corrosion monitoring and inspection provide information on effectiveness of existing corrosion control program and suggestion on improving the corrosion control program. Corrosion is an electrochemical reaction, and corrosion control employs methods which inhibit the electrochemical reaction to proceed readily, viz., applying suitable material and modifying environment conditions result in reduction of ionic transfer rate, using protective coating prevents occurrence of anodic/cathodic half cell reaction and utilizing cathodic protection effectively alter direction of electron transfer. However, environment conditions continuously fluctuate, corrosion can thence be controlled in certain periods of time but aggressive in other periods of time. Ideally, corrosion control methods have then to be adjusted instantaneously according to the change in environment conditions in order to ensure the performance of these methods. Importantly, control of corrosion in constantly changing environment conditions is feasible with real-time corrosion monitoring. Figure A below shows a section of metal loss versus time data obtained from Electrical Resistance (ER) probe with approximately real-time corrosion monitoring configuration. The sharp peaks may originated from the changes in environmental conditions. Figure A. Metal loss versus time data viewed using Korosi Monitoring System (KMS) software.

Corrosion Monitoring, Inspection and Control Methods Online (non-interupted) corrosion monitoring allows access to corrosion data as often as needed in a facility while it is on service without the necessity to shut-down the facility. Even, the installation and maintenance of online corrosion monitoring require no shut-down of the facility. In accordance to the fact that corrosion takes place at the interface of corroded material and corrosive substance (electrolyte), intrusive type of online corrosion monitoring method are proven to be powerful in the oil and gas, petrochemical and water treatment fields. KOROSI SPECINDO manufactures several intrusive type online corrosion monitoring equipments as follows: 1. Corrosion coupon 2. Electrical Resistance (ER) probe 3. Linear Polarization Resistance (LPR) probe KOROSI SPECINDO also offers several options of corrosion Data Collection Instrument (DCI) along with the ER/LPR probe, namely: i. Portable data logger ii. Field mounted data logger iii. Field mounted data transmitter In order to meet the field s restrictions, these instruments are available with various configurations and they, along with their production process, have obtained certifications from ATEX and IEC for application in potentially explosive atmosphere. Ultrasonic thickness, dye penetrant and magnetic particle testings are types of non-destructive testings that KOROSI SPECINDO can offer for the corrosion inspection service. Due to practical and economical reasons, modifying environment conditions is favorable for mitigation of corrosion by means of chemical injection, i.e., oxygen scavenger, scale inhibitor, biocide and etc. Aside from the corrosion monitoring equipments listed above, We also supply online corrosion control equipment, namely, Chemical Injection and Sampling Systems. It is to be noted that these corrosion monitoring methods have both advantages and disadvantages, which are elucidated in the remaining of this catalog, in term of capability to explain the causes and effects of progressing corrosion. Combination of several of these corrosion monitoring methods are often required by corrosion engineer to provide sound solution. Meanwhile, for enhancing the usefulness of corrosion data, KOROSI SPECINDO has developed our intrinsically safe data transmitter for the purpose of real-time corrosion monitoring as well as other types of Data Collection Instrument (DCI). The real-time corrosion monitoring coupled with processing parameters monitoring should be powerful tools for determining the cause of and then the solution for occurring corrosion at its earliest stage.

8 KOROSI SPECINDO 1-1 MODEL KS200 SERIES-TWO INCH SYSTEM CORROSION COUPON HOLDER ASSEMBLIES 1. Principle of Operation Corrosion coupon is a method of online corrosion monitoring employing mass-loss measurement. A coupon is a metallic specimen which composition and condition of state are approximately similar to those of the facility being monitored. After exposure to various fluids and flow conditions for certain period of time, the coupon is later retrieved for examination and evaluation in order to determine the cause and extend of corrosion. The extend of corrosion is generally represented by corrosion rate. The cumulative corrosion rate throughout the exposure period is accordingly calculated using the equation as follows, corrosion rate = m loss/(.t.a), where mloss is mass-loss, is density, t is total exposure period and A is the exposed area. Furthermore, corrosion coupon accesses other additional information which other methods can not provides, viz., scale formation and types of corrosion, such as, pitting, galvanic, crevice and stress-related corrosion. In laboratory tests, corrosion coupons made of different materials are also commonly used for selection of appropriate material. Wide selection of corrosion coupon and holder as illustrated in Fig. 1-1 is available for comprehensive range of application and operational condition. Flush configuration is primarily used in locations where pigging is performed. Whereas, projecting configuration permits exposure of the coupon to the corrosive phase in a multi phase fluid. All design and processing of corrosion coupon and holder assembly meet NACE RP and NACE MR0175/ISO standards.

Corrosion coupon is available in many different shapes and materials for diverse objectives. Strip coupon is mounted in pair and immersed in the phase of interest within a multi phase fluid. The strip coupon comes in 3" or 6" in height to ensure adequate observation area for good analysis. Scale coupon has a strip shape and different size holes so that scaling tendency can be monitored. Flush disc coupon is positioned flush to the surrounding surface and, hence, closely represents the actual surface condition. Multiple disc coupon allows comparison of corrosiveness of different phases simultaneously. Ladder strip coupon functions similarly to the multiple disc coupon but it is installed in pairs, as demonstrated in Fig Rod coupon serves the same purpose with the strip coupon however the more number of coupon installed enhances result accuracy. Model KS200 series-corrosion coupon holders are used in conjunction with Model KS6000-two inch access fittings for high pressure application. For safety reason, we offer non-weld type design and AISI 316 SS as standard material. All coupon holders are furnished with insulator to avoid contact between the coupon and the holder. Fig KS200-strip coupon holder. Model KS200-strip coupon holder is for holding a pair of 3" or 6" strip or scale coupon. Length is available from minimum 2.50" and beyond. Model KS201-adjustable disc coupon holder is intended for usage with only 5.25" height flarweld and buttweld type access fittings. The adjustable disc coupon accommodates many pipe wall thickness for flush mounting.

13 1-6 KOROSI SPECINDO CORROSION RATE CALCULATIONS: Weight Loss Coupons To calculate average corrosion rate as uniform rate of thickness loss per unit time mils per year (mpy), use the following equations : Where : ''CR'' ''W'' ''A'' ''T'' ''D'' CR = W x 365 x ATD x (2,54) 3 = x W ATD is Average Corrosion Rate, mils per year (mpy) is the weight loss due to corrosion and is determined by subtracting the weight after cleaning from the initial weigh, grams (g) is the surface area of the coupon that is exposed to the corroding process, 2 square inches (in ) is the period in days between installation and removal of the coupon, days (d) 3 is the density of the coupon or coupon alloy from the table in the next page (g/cm ) The above equations is used for calculation of corrosion rate in mpy (mils per year) when the area of the coupon is in inches and the time of exposure is in days. For other units of measure example in millimeter per year (mmpy), use the following equation: W x 365 x x 10 3 W CR = = ATD ATD Where : ''CR'' ''W'' ''A'' ''T'' ''D'' is Average Corrosion Rate, mils per year (mmpy) is the weight loss due to corrosion and is determined by subtracting the weight after cleaning from the initial weigh, grams (g) is the surface area of the coupon that is exposed to the corroding process, 2 square millimeter (mm ) is the period in days between installation and removal of the coupon, days (d) 3 is the density of the coupon or coupon alloy from the chart next page (g/cm ) To calculate of the maximum Pitting Rate (PR), use the following equation PR (mmpy) = Depth of pit (mm) x 365 Exposure time (Days) EXAMPLE A mild steel coupon weighing grams and having an exposed area of 2.96 square inches was th th installed in a process on August 27 and on November 13, After 78 days in the process, it was removed, cleaned and weight found to be grams. From the chart on the next page the 3 density was found to be 7.86 g/cm. The corrosion rate calculation for this period is: x 10 x ( ) 2.96 x 78 x 7.86 = CR (mpy)

15 SECTION 2 TWO INCH SYSTEM ELECTRICAL RESISTANCE (ER) PROBE AND DUAL ER/TEMPERATURE PROBE

16 KOROSI SPECINDO 2-1 TWO INCH SYSTEM ELECTRICAL RESISTANCE (ER) PROBE AND DUAL ER/TEMPERATURE PROBE 1. Principle of Operation Electrical Resistance (ER) probe is analogues to corrosion coupon that these corrosion monitoring methods require sacrificial elements to be corroded prior to determination of corrosion rate. However, unlike the corrosion coupon which must be retrieved periodically, the ER probe needs no retrieval through out the life time of the element. Using a Data Collection Instrument (DCI), which will be presented in Section 4, electrical resistance of the element with fixed length and cross-sectional area is monitored at specific time. Since the electrical resistance of a material is explained by the following equation, R=.l/A, where, land Aare resistivity, length and cross-sectional area of the material, respectively, the change in instantaneous cross-sectional area of the element is easily obtained. Metal loss during exposure period can then be calculated from reduction of the cross-sectional area and, hence, the corrosion rate can be derived from graph of the metal loss and exposure period. Furthermore, the corrosion rate commonly represents the result of general corrosion since the ER probe is generally not sensitive enough to detect localized increase of the electrical resistance due to pitting corrosion. It is obvious that the ER probe is not suitable for application in a medium which is conductive and susceptible to scale formation. Therefore, the application of the ER probe is limited to a low conductive medium or intermittent conductive medium and, notably, the usage of the ER probe is preferably accompanied with the usage of other corrosion monitoring method. Temperature is one of important processing parameters. As the resistivity of a material depends on temperature, its variation thence contributes to alteration of electrical resistance reading of the ER probe. However, the effect of temperature on the resistivity of the probe s element can be compensated by having a reference element of identical material to the probe s element protected from corrosion. The change of the cross-sectional area of the probe s element due to corrosion then can be calculated from the ratio of the probe s element resistance and the reference element resistance. Moreover, temperature also strongly influence corrosion process, hence, it is often advantageous to have temperature data available along with corrosion data. In addition to the ER probe, KOROSI SPECINDO therefore also offers dual ER/temperature probe for simultaneous measurements of corrosion rate and temperature. The temperature measurement is based on Resistance Temperature Detector (RTD) which working principle is briefly mentioned above.

17 2-2 KOROSI SPECINDO 2. Probe Type, Length Calculation and Ordering Procedure KOROSI SPECINDO manufactures various types of ER probe based on shape of the sacrificial element, i.e, tubular, wire/tube loop and flush, designed for different purposes and wide range operating conditions. Installation of the two inch system ER probe is done in combination with the KS6000-two inch access fittings. Material design of the ER probe follows NACE MR0175/ISO15156, and the standard materials of the probe body are mild steel or AISI 316 stainless steel. The sacrificial element of designated material is connected to the ER probe body by sealant. Epoxy, glass and weld sealants are commonly used for exposure to various temperatures, pressures and chemicals. As protective measure in case that the sealant fails, filler made of alumina is employed. The present schematic drawing shows several installation configurations of ER probe, viz., flush/top, middle and bottom, with non-flange and flange access fittings. Remark LA : height of access fitting WG : weld gap=0.0625" (ANSI B ) PW : pipe wall thickness FG : flange face-to-face gap MF : mating flange height POD : pipe outer diameter LE : height of sacrificial element (LE=2" for short tubular element, LE=4" for long tubular element, LE=1.5 for wire/tube loop element, LE=0.95" for stripband element) Sensitivity and life time are determining factors for selection of ER probe. Sensitivity is a measure of the probe readiness to detect corrosion. Sensitivity increases with decrease of the probe s element thickness. In contrary, the probe s life time is shortened with the decrease of the probe s element thickness. Table 2-1 on the next page provides information on sensitivity and life time for several ER probes. The remaining of this section will explain the various types of ER probe in more detail along with length calculation and ordering procedures. Furthermore, existence of sand causes erosion problem. Similar to corrosion rate, erosion rate can be monitored using the electrical resistance method. Sand-erosion probe is purposely developed for monitoring erosion rate, and it will also be explained later in this section.

29 SECTION 3 TWO INCH SYSTEM LINEAR POLARIZATION RESISTANCE (LPR) PROBE AND DUAL LPR/TEMPERATURE PROBE

30 KOROSI SPECINDO 3-1 TWO INCH SYSTEM LINEAR POLARIZATION RESISTANCE (LPR) PROBE AND DUAL LPR/TEMPERATURE PROBE 1. Principle of Operation Linear Polarization Resistance (LPR) probe measures corrosion rate in a different way from corrosion coupon and ER probe. Corrosion coupon and ER probe concern on change in physical property of the sacrificial element during corrosion process, namely, mass-loss and electrical resistance, respectively. Meanwhile, LPR probe focuses on change in electrochemical property of a material, particularly, corrosion current. It is a result of electron transfer from anodic half-cell to cathodic half-cell and directly proportional to corrosion rate. However, a satisfactory method to measure the corrosion current is still not available since locations of anodic and cathodic half-cells constantly change. One method to obtain an approximate value of corrosion current is by applying small potential difference on a material undergoing corrosion process and monitoring the resulting current. The material under such condition is termed in polarized state and, subsequently, the resistance calculated from the applied potential and measured current is named polarization resistance. The polarization resistance is inversely proportional to the corrosion current and, importantly, corrosion rate. LPR probe was developed for practical measurement of approximate polarization resistant, corrosion current and corrosion rate, successively. LPR probe employs two or three electrodes immersed in the solution of interest to convey current electrochemically through the solution from one electrode to another when small potential difference, mv, is applied between the electrodes. The potential difference must overcome the polarization resistance of the first electrode, electrical resistance of the solution and the polarization resistance of the second electrode. In the case of LPR probe with two electrodes, electrical resistance of the solution is a major concern. When the solution resistance is low, the calculated resistance (applied potential difference/measured current) is comparable to the polarization resistance. In contrary, when the solution resistance is high, the calculated resistance is substantially larger than the polarization resistance and, consequently, the corrosion current and corrosion rate are underestimated. Hence, the two-electrode LPR probe is limited for usage in the solutions with high conductivity. In the case of LPR probe with three electrodes, the solution resistance is rendered less-influential due to the addition of the third electrode. When the potential difference is applied on the three-electrode LPR probe, a pair of electrode is used for measurement of voltage necessary for transmitting current through the solution, then, the required voltage is applied between the other pair of electrode for current measurement. Nevertheless, the three-electrode LPR probe is recommended for application in high conductive and continuous-flow solution for accurate determination of corrosion rate.

31 3-2 KOROSI SPECINDO It is also to be noted that like ER probe, LPR probe does not perform well in a solution where scaling occurs and it gives only a uniform corrosion rate. But unlike ER probe, LPR probe responses rapidly to provide corrosion rate directly so that correlation to changes in the process can be made and, hence, it can point out when and why corrosion takes place. In addition to LPR probe, KOROSI SPECINDO also supplies dual LPR/temperature probe for comparison of corrosion rate and temperature. 2. Probe Type, Length Calculation and Ordering Procedure KOROSI SPECINDO offers two types of LPR probe, i.e, projecting and flush. The two inch system LPR probe is for usage in combination with the KS6000-two inch access fittings. Material design of the LPR probe complies to NACE MR0175/ISO15156, and the standard materials of the probe body is AISI 316 stainless steel. The electrodes of selected material are connected to the LPR probe body by glass, PEEK or epoxy sealant. Filler made of alumina is also employed to provide additional protection. The present schematic drawing shows several installation configurations of LPR probe, viz., flush/top, middle and bottom, along with non-flange and flange access fittings. Remark LA : height of access fitting WG : weld gap=0.0625" (ANSI B ) PW : pipe wall thickness FG : flange face-to-face gap MF : mating flange height POD : pipe outer diameter LE : height of electrode (LE=1.6" for projecting electrode) The remaining of this section will explain the two types of LPR probe in more detail along with length calculation and ordering procedures.

Specifications Mounting : Model KS6000- Two Inch Access Fittings Temperature Rating : 260 C Pressure Rating : 3600 psi Probe Body Material : AISI 316 SS / Duplex SS Sand-erosion monitoring system is used to detect wall-thining of pipeline caused by sand-erosion. The sand-erosion monitoring system explained in Section 2 operates based on Electrical Resistance (ER) measurement. Meanwhile, the sand-erosion monitoring system in the present section simply consists of sacrificial element without the ER measurement involved. The sacrificial element is closed at one end and has thread at the other end to connect to the sand probe nut shown in Fig The sand probe nut enables the sacrificial element to be attached to the solid plug and used in KS6000-access fitting assembly with tee. The effect of sand eventually erodes through the sacrificial element, exposing the closed end to the operating pressure. The fluid flow is then directed through ports in the sand probe nut to the tee portion of the access fitting body. Through the nipple and shut-off valve, the fluid flow pressure is indicated by the pressure gauge. The sacrificial element is 5/8" in Outer Diameter (OD) and available in three wall thicknesses: 0.016", 0.028" and 0.035". The 0.016" thickness is standard wall thickness for 2" OD pipe, 0.028" thickness is standard wall thickness for 3" to 6" OD pipes and 0.035" thickness is standard wall thickness for 8" and larger OD pipes.

50 5-2 KOROSI SPECINDO The sacrificial element is constructed from AISI 316 SS or Duplex SS, and it complies to NACE MR0175/ISO15156 for practice in Sulfide Stress Cracking (SSC) induced environments. The placement of the sacrificial element is approximately inserted 60% into pipeline Inner Diameter (ID). This placement allows for maximum sand impingement at center of line where flow velocity is the greatest while still permitting heavier suspended particles, riding slightly lower in the flow stream, contact the sacrificial element.

Specifications Mounting : Model KS6000- Two Inch Access Fittings Temperature Rating : 260 C Pressure Rating : 3600 psi Probe Body Material : AISI 316 SS Monitoring Sulphate Reducing Bacteria (SRB) is recognized as an important task of understanding and controlling corrosion. Producing good quality biofilm samples from any closed system is an essential first step to successful SRB monitoring. SRB probe consists of Delrin/glass-filled PTFE holder housing six removable studs. The SRB probe is mounted on the standard solid plug in the access fitting assembly. The six studs can come in any material required. SRB probe is usually inserted in dead-leg locations where the biofilm formation is most likely to occur. Typically installation of the SRB probe is bottom of line and flush installation. In cases where the dead-leg locations are not available, flow over the studs needs to be reduced using the fixed shield option available for this product.

54 5-6 KOROSI SPECINDO TWO INCH SYSTEM HYDROGEN MONITORING PROBE 15 Vacuum gauge Bleed cross assembly Capillary tube Bleed cross assembly Adhesive patch Non-intrusive hydrogen probe Intrusive hydrogen probe Fig Hydrogen monitoring systems. Hydrogen atoms often produced in acidic environments can permeate through steels and, later, are released as hydrogen molecules which lead to hydrogen induced cracking and hydrogen blistering. Several techniques for hydrogen monitoring, i.e., intrusive and non-intrusive/patch types, make use of the fact that the released hydrogen gas will build up pressure. Intrusive hydrogen probe consists of a steel tube exposed to the process and connected to a bleed cross assembly which is equipped with a pressure gauge, thermometer and bleed valve. The thermometer is used to measure the temperature of the hydrogen gas so that volume calculation can be made using temperature and pressure, whereas, the bleed valve is for releasing the pressure build-up periodically. An exposure length of 3" is standard for the intrusive hydrogen probe and the wall thickness is usually thinner than the pipe wall allowing shorter response time. The intrusive hydrogen probe may be removed and replaced under operating pressure permitting online replacement or inspection of the tube. Non-intrusive hydrogen monitoring is established by mounting the bleed cross assembly directly into an NPT threadolet welded to the pipe wall with a blind installation (no penetration of the pipe wall). A sealed pocket existing in between the bleed cross assembly and threadolet allows for the pressure build-up. The non-intrusive hydrogen monitoring is slower to respond than the intrusive hydrogen probe due to the time taken for the hydrogen atoms to permeate the full pipe wall thickness, but the result is representative of the actual pipe wall.

55 KOROSI SPECINDO 5-7 Adhesive patch hydrogen monitoring requires no welding as the patch is secured with an adhesive. A thin capillary tube connects the patch to a manifold block on which a vacuum gauge and evacuation/test outlet are equipped. The adhesive patch entraps the hydrogen gas in a small pocket between the pipe wall and the adhesive patch that is fixed to the pipe wall at its edges. The pocket is vacuumed using a small hand pump, and the vacuum state must be re-established periodically. Successive time measurements of vacuum decay can be employed to calculate the hydrogen flux rate. Temperature correction is not necessary with the adhesive patch hydrogen monitoring making the recording and calculation simple. The test outlet is used with a gas tester to confirm that the hydrogen is the cause of the vacuum decay. The manifold assembly comes in a polycarbonate housing and additional length of capillary tube can be ordered to allow the manifold block to be located at some distance from the adhesive patch, enabling the device to be applied on burried pipeline.

Chemical injection/sampling system is fundamental to corrosion control program and it is applicable to various processes in the petroleum, chemical and water treatment industries. The chemical injection system may be used for the injection of wide range of chemicals such as biocide, demulsifier, corrosion inhibitor, oxygen scavenger, glycol, dewaxer, methanol and odorizer. The sampling system is used to take samples of the process fluid. The samples are then analyzed in the laboratory for corrosion inhibitor concentration, presence of metal ions, oxygen concentration and scale forming compounds. The chemical injection system is a complex technology. Principle factors related to the chemical injection and process systems are as follows. 1. Pressure differential: It is the difference between the injection pressure and the process line/vessel pressure. 2.Viscosity: It is a measure of the fluid resistance to flow. The more viscous the fluid, the smaller the spray angle. 3.Temperature: It directly affects viscosity.

58 5-10 KOROSI SPECINDO 4. Spray angle: It is affected by viscosity, spray distance and pressure differential. 5.Spray coverage: It is calculated theoretical area covered. 6.Specific gravity: The specific gravity of a liquid is the density ratio of the liquid to water. The flow rate of a liquid is affected by its specific gravity. Injection rate is the amount of chemical to be injected within a specified time period and it is defined as liter per hour or Gallon Per Hour (GPH). Injections systems are available for injection rates varying from 0.38 liter per hour (0.1 GPH) to 250 liter per hour (65.7 GPH). The maximum fluid velocity is usually at the center of line, hence, the most effective position for injection is generally at the center of the pipe in the direction the product flow. If the pipeline is to be pigged, the injection position should be flushed with the pipe wall which eliminates the need to remove the injection probe before the pigging operation. A typical two inch system chemical injection/sampling system is shown in Fig. 5.4 which consists of as in the followings. 1.Access fitting body with a side tee through which the fluid transfer takes place. The tee may be connected to a nipple or flange by thread or weld. The tee size is rated according to the injection rate and pressure of injection. 2.Solid plug assembly fitted inside the access fitting body is used to hold an injection nut which has injection/sampling tube screwed/welded to its base. 3. Protective cover provides heavy duty protection on both the access fitting body and solid plug assembly. 4. Injection/sampling nut transfers the injected liquid into the process or sampled liquid out of the pipeline or vessel. 5.Injection/sampling tubes are available in various end forms, namely, open, quill, NPT and head ends. Open and quill end tubes rely on the natural turbulence within the pipeline to disperse the injected chemical. These tubes are clog proof and, particularly, the quill end tube give good dispersion provided that the product flow is greater than 4.6 m/s. NPT end tube is similar to the open end tube but it is threaded, thus, allowing attachment of a female nozzle. Head end tube is usually used for parallel injection at the center of the line, and it is designed to accept the standard nozzle assembly. 6.Atomization nozzle permits atomization of the fluid as it is injected into the pipe line or vessel. The atomization nozzle comes with either male or female NPT thread, and it contains cap, core and strainer. Chemical injection/sampling system components are manufactured from AISI 316 SS which complies to NACE MR0175/ISO15156 for practice in Sulfide Stress Cracking (SSC) induced environments.

90 KOROSI SPECINDO 7-1 TKS R RETRIEVER AND ACCESSORIES On line retrieval of corrosion coupon and replacement of corrosion probes is essential for effective corrosion monitoring of continuous process. Retriever and service valve tools are designed to provide this capability when used with the two inch system access fittings. The retrieval tool is available with 3600 psi pressure rating and a variety of lengths to suit the corrosion coupon holder and probe lengths to be retrieved. Model TKS R retriever and TKS K service valve tools can be used for any KOROSI SPECINDO two inch system access fittings. The major components of the retriever are a stationary inner barrel, thread adapter, moveable stainless steel outer barrel, mandrel rod and socket adapter assembly which are in accordance to NACE MR0175/ISO Sealing within the unit is achieved with viton o- ring, teflon back up rings and graphite impregnated teflon seals. A bleed valve assembly incorporated in the retriever allows product bleed-off away from the operator for safety and cleanliness. It can be also used for back pressuring and product sampling. The TKS R-retriever operates using pressure balance principle ensuring that it extends and collapses in a safe and easily controlled way. Balance is achieved by equalizing valve and ports. Careful maintenance is essential to obtain maximum life from the equipment. Tools and valves should be dismantled and cleaned after each use and seals should be replaced regularly. Seals and spare parts are available to provide the necessary minor and major overhauls. The TKS R-retriever assembly is equipped with service tools and supply of spare parts. These tool kits are contained in a sturdy box to provide easy storage and portability. The retriever with standard stroke lengths are indicated below and longer stroke length is available on special order basis. Please contact KOROSI SPECINDO for detail. Fig Model TKS R Retriever

92 KOROSI SPECINDO 7-3 TKS K SERVICE VALVE AND ACCESSORIES The complete service valve kit includes TKS service valve assembly with extension lever, brass hammer and a heavy duty field service box for safe storage and easy portability. The TKS service valve assembly is especially designed for use with two inch system access fittings and TKS R-retriever. Attached to the access fitting body, the valve is the control which allows the pressurized product to enter the retriever during insertion and removal of KS100A solid or KS120A hollow plug assemblies. The service valve complies to API 6FA and API 607 as a fire safe unit. The service valve assembly also contains the pressurized product when the retriever is disconnected. Retriever and service valve hook-up is indicated in Figure 1. The service valve assembly is basically a ball type valve with full-opening port with a special pressure equalizing port which allows the operator to slowly release line pressure to the retriever. With pressure balanced on both sides of the ball, the valve can be operated without difficulty or torque problems, even on high pressure systems. The valve also incorporates a secondary special built-in vent to atmosphere valve allowing product bleed-off away from the operator for safety and cleanliness. With the aid of the optional accessory, diverter hose assembly, the bleed valve can also be used for product sampling, back-pressuring for product or pressure relief. Should the solid or hollow plug thread, packing, or o-ring become damaged, preventing service valve removal, a service valve blanking plug can be used to seal the open end of the valve. Fig TKS service valve assembly. The service valve blanking plug, available as an optional accessory, is mated to the ACME thread of the service valve after removing the retriever. This provides a secondary seal for the valve. The service valve can then be left in place, completely sealing the access fitting until corrective repairs can be made at a later time. Flanged valves, alternative materials and high temperature valves are available on special order.

101 KOROSI SPECINDO 8-1 ONE INCH RETRACTABLE ACCESS SYSTEM GENERAL OVERVIEW An extremely reliable access system widely used by the petrochemical and oil production industries. A simple and versatile method of access to a process stream for on-line insertion and removal of coupons, probes, injection and sampling systems. Suitable for service at 1000 psi or 1500 psi with options for additional back up seals in gas applications. The operating temperature of 260 oc may be extended to 450 oc by the use of graphite packing provided the insert component is also compatible. One inch retractable access system comprises of a packing gland assembly, coupon holder/probe, safety clamp and branch assembly with valve. The coupon holder, probe or inserted device has a diameter of 5/18" and stainless steel body, which can slide through the packing seal while retaining pressure integrity. The packing assembly is mated to the ambient side of the valve so when it is open the inserted device can be inserted into the process stream. The reverse process allows the inserted device to be retracted, then, the valve can be closed and the packing gland assembly can be removed for servicing. The inserted device is secured in place with an additional plate and rod of the safety clamp. For operating pressure above 250 psi, it is adviseable to use a retractor tool which provides mechanical advantage and safety during the insertion and retraction cycles. The packing gland assembly is available with 1" FNPT or flanged connection and AISI 316 SS body. Seals are reinforced PTFE. It is important that the internal diameter of any existing branch assembly is clearly identified before ordering equipment. A minimum 7/8" hole diameter on the valve must be provided since the safety stopper inserted devices has 3/4" diameter. The following pages provide detailed information on length calculation and ordering procedure for the one inch retractable access system.

118 8-18 KOROSI SPECINDO MODEL L300 SERIES LABORATORY AND NPT PROBE (FLUSH, TUBULAR, WIRE LOOP AND TUBE LOOP) Fig Model L300 NPT fixed ER probe. Specifications Ø Maximum operating pressure : 100 psi (laboratory probe) Ø Temperature Rating 1500 psi (NPT probe) : 150 oc (epoxy sealant) 260 oc (glass and weld sealants) Ø Material of construction : AISI 316 SS Ø Element seal : Epoxy, glass or weld Ø Probe body material : AISI 316 SS This selection of corrosion monitoring probes cover a complete range of ER and LPR probes in low and medium pressure configurations. These probes are for fixed installation and they can not be installed or changed in pressurized systems without shutdown. Laboratory probe is used for a variety of low pressure tasks. It has no threaded mounting but it is suitable for use with laboratory glass compression fittings and rubber bung insertion. The standard probe is epoxy sealed with stainless steel body. NPT fixed probe has a fixed insertion length below the NPT mounting thread. It is used for a variety of industrial corrosion monitoring tasks, such as, a pressurized test rigs or side stream test. It is suitable for interruptible and batch processes or locations where temporary isolation is available for installation and retrieval. The NPT thread configuration requires only a simple threadolet type fitting on the target pipework or vessel. NPT adjustable probe is similar in most respects to a NPT fixed probe with the added benefit of a variable insertion length through an addition of a swagelock tube fitting, ideal for applications where the equipment may be moved between locations with different insertion requirements due to variation in pipe diameter and wall thickness.

119 KOROSI SPECINDO 8-19 INSTRUMENT CONNECTIONS All probes are fitted with a 6 pin Mil-C-5015 connector which is compatible with all KOROSI SPECINDO instrumentation and any other instruments. All probes connectors are stainless steel with silver plated pin and threaded shells. Fig General arrangement drawing of NPT ER probe. CALCULATING PROBE LENGTHS FOR NPT PROBES In order to calculate the length of NPT probes, please refer to Fig. 8-9 and ensure the following informations are available: 1. The height (H) of the threaded fitting (threadolet) above the pipe wall in milimeters 2. The wall thickness (W) of the pipe in milimeters 3. The distance of the probe s element that extends beyond the pipe wall in milimeters Look up the thread make-up distance (T), in Table 8-5, for the probe model you have selected. Order length = (H+W+D)-T Once you have calculated the order length, please refer to the Table 8-5 to find either: 1. A standard fixed probe length that is close enough in length to meet the requirement 2. A standard adjustable probe length with an insertion length that exceeds the order length required In either case, if you find that the standard probe length will meet the requirement, insert the letter STD into the product code section for length. If the standard probe length does not meet your requirement, insert the calculated length in millimeter into the probe code, remembering to use a three digits whole number e.g.: 098. Please note: it is not possible to order probes shorter than the minimum length for each type given in the table. In the case of adjustable probe, the minimum length and the order length define the lower and upper limits of the possible insertion. For example: a standard 1" NPT tubular probe with adjustable length has a possible insertion range between 125 mm and 325 mm below the probe thread. Accessories: we can supply mounting threadolet in all sizes and most materials, as well as extension cables.
