Page : Page 5 of 19 2.0 INTRODUCTION FLOCLEAN Model 424 & 425 Basket Strainers are devices installed in a pipeline to remove sediment and debris from fluids. Straining is accomplished by directing the fluid through sized openings in the element. Once sediment and debris is collected in the screen, fluid flow is interrupted while the screen is removed for cleaning. 2.1 SYSTEM DESCRIPTION Model 424 & 425 fabricated Basket Strainers consist of six basic components: Basket Pipe: provides an in-line attachment capability for the connection pipes to which the line process flanges are eventually welded. In addition, element baffle plate or seat is welded to provide for element fitment. Pipe Closures provided at the top are either the bolted types or the quick opening types as specified. Basket Pipe selected is based on the ratio and is undoubtedly the factor on which the strainer price is determined. Connection Pipe: provides an in line attachment capability as the process flanges are welded to the same. Basket Pipe Covers: are provided with a recess or an O ring groove for the gasket and an effective method of compressing and sealing gaskets. The cover also compresses the element handle through a bolt to eventually ensure that there is no by-pass through the element. Element: Placed on the baffle plate or element seat and is compressed by the cover under bolting loads. The element handle is sized to ensure that it does not rotate under bolting loads thus ensuring zero-particle by pass..elements are manufactured in materials compatible to the flowing fluid and the openings provided are based on the degree of filtration requested. Sealing Gaskets: the sealing gasket is placed in the recess / O ring provided in the covers and are compressed by the bolts and nuts to effectively seal the gap and prevent leaking between the body pipe and the cover plate. A variety of materials ensure that the gaskets are compatible to the fluid passing through the Strainer. Bolt Nuts : compress the gaskets between the body and the cover plate. 3.0 AVAILABLE MODELS Model Flanged Ends In Line Off Line Specified Degree Orientation Filtration 424 h h 40 mesh 425 h h 40 mesh 425-OL h h 5 micron of Table 1

If damage is evident or suspected do not attempt installation. Notify carrier immediately and request damage inspection. 2) Remove any preservatives with solvent damped cloth. Exercise care when using solvent and follow solvent manufacturer s instructions. 3) Verify that the rating of the strainer is greater than or equal to the maximum pressure on the installation. 4) Inspect the strainer by checking for and removing any foreign or loose material that could be carried downstream when fluid is introduced in the strainer. 5.0 INSTALLATION
Page : Page 8 of 19 Qualified experienced personnel who are familiar with this equipment and have read and understood all the instructions in this manual should undertake installation. The user should refer to C-TRU PROCESS EQUIPMENTS product proposal to obtain overall dimensional information. 1) Do not proceed with installation of the strainer unless the connections and inside of the strainer have been cleaned and are free of any foreign material. 2) Do not proceed with installation of the strainer till you have reviewed the application and chemical compatibility of the process fluid to the materials of construction of the strainer. 3) Do not proceed with installation unless you have ascertained that sufficient clearance is provided for easy opening of the cover and removal of the basket. 5.1 EFFECTS OF RELATED PIPING 1) Do not impose system-piping loads on the strainers. Unit is not designed to be a load-bearing component. Piping must be supported and aligned with strainer end connections to reduce the possibility of stresses imposed on the unit. Large heavy units must be independently supported to avoid stressing the piping. 2) Locate the strainer where it can be easily accessed for cleaning. 3) When bolting units to adjacent piping, care must be taken to ensure that bolts or studs do not project sufficiently past the flange to strike any part of the strainer thus avoiding potentially stripped flange connections or movement of the preset retainers. 5.2 INSTALLATION POSITION 1) Remove protective wraps before installing the strainer into operation 2) A Basket Strainer has to be installed in a horizontal position.
IOM Revision : 00 Page : Page 9 of 19 3) Once again confirm that sufficient clearance is provided for easy opening of the cover. 4) Connect the strainer to the pipeline with a compatible companion flange face. Do not bolt a raised face flange to a flat face flange. Ensure flange gaskets are in place and fasteners are tight. 5) If specified, Basket Strainers have provision to accept gauges. Pressure Gauges near the inlet and outlet are required to determine differential pressure across the strainer and cleaning frequency. Pressure Gauges are essential for the safe operation of a strainer and should be installed using standard piping practices. 6) It is recommended that a compatible valve (and piping as needed) be installed in the cover (blow off) for safe quick clean out (normal blow down cleaning). To protect the operator while draining and clean out, the fluid must be piped to a safe area by using the valve mentioned in 6 above. This requirement is for all fluids and also for water where the temperature is exceeding
Page : Page 10 of 19 48 0 C. The operator should wear appropriate protective equipment consistent with the process fluid for strainer operation and servicing 6.0 OPERATION The problem of unwanted material in pipelines is a never-ending one. Whatever be the flowing material there is often something present that can cause trouble. Strainers remove foreign particles from the pipeline flow. They are relatively inexpensive compared To the equipment they protect To the down time. Inferior products. Loss of production If they are not installed in the piping system. 6.1 PRE OPERATIONAL CHECK 1) Ensure that all installation procedures have been completed. 2) Check to determine that all connections are pressure tight. 6.2 HYDROSTATIC PRESSURE TEST 1) Take all precautions necessary to handle the possibility of leakage. 2) Pressure test all installations hydrostatically to at least 5 Kg/cm 2, and correct any leakage before proceeding. 6.3 OPERATING 1) Open blow down valve to expel air from the strainer. 2) Slowly allow the fluid to enter the strainer Strainer installations should be brought into service slowly to avoid excessive shock or stress. This is extremely important for steam service
Page : Page 11 of 19 3) Close vent when fluid begins to flow. 7.0 MAINTENANCE Qualified experienced personnel who are familiar with this equipment and have read and understood all the instructions in this bulletin should undertake maintenance. Do not proceed with any maintenance unless the strainer has been relieved of all pressure or vacuum, has been allowed to reach ambient temperature and has been drained or purged of all fluids. 7.1 PREVENTIVE MAINTENANCE The user must create maintenance schedules, safety manuals and inspection details for each specific installation. On all installations the user should regularly evaluate the following items for purpose of maintenance: 1) Strainer, for signs of leakage at gaskets or at connections. 2) Strainer, for signs of internal or external corrosion. 3) Clogging of strainer. The user must determine upon evaluation of his or her own operating experience an appropriate maintenance schedule necessary for his or her specific application. Realistic maintenance schedules can only be determined with full knowledge of the services and application situation involved. 7.2 MAINTENANCE PROCEDURES 1) Gaskets: A strainer that leaks at the gasket must be immediately taken out of service. Do not proceed with the operation of a strainer until gaskets have been replaced. 2) Connection Leaks: A strainer that leaks at the connection should be corrected by tightening the bolts at the connection, 3) Corrosion: While we do recommend materials, on request or when the materials requested by the user is ambiguous what we eventually supply is what the user has insisted upon. If internal or external corrosion is present the user as to the cause of the problem should immediately carry out an investigation.
Page : Page 12 of 19 4) Clogging: A differential pressure of 5 10 psig indicate clogging and this requires the basket to be removed and cleaned 7.3 SHUT DOWN PROCEDURE 1) Slowly close the pipeline valves upstream and downstream from the strainer. Ensure that the valves are tightly closed and are not passing any fluid. 2) Relieve fluid pressure in the strainer by first opening the drain and then the vent. The strainer must be drained and internal pressure relieved prior to cleaning. Now proceed to clean the element. 7.4 WHEN TO CLEAN THE ELEMENT A differential pressure increase of 5 to 10 PSI indicates that the strainer is full of debris and needs to be removed. To prevent strainer damage do not permit differential pressure across the strainer to exceed 20 PSI. 7.5 ELEMENT REMOVAL, CLEANING & REPLACEMENT 1) Follow the shut down procedures outlined above. 2) When the strainer s internal pressure is relieved, drain the fluid and remove fasteners. Remove cover (blowoff). 3) Remove the debris laded element.
Page : Page 13 of 19 Do not permit the element debris to dry as then it would be difficult to remove and clean the element. 4) Invert the element and wash out debris by directing a stream of water or air against the element exterior. 5) Inspect element at each cleaning for holes or tears. Replace as needed with genuine FLOCLEAN elements. Always keep spare elements and gaskets in stock. 6) Inspect sealing surfaces and cover gasket. Clean sealing surfaces. 7) Place cleaned/new element in basket pipe. Care must be taken to assure that basket ellipse ring rests squarely on the elliptical retaining ring welded in the basket pipe 8) Ensure that the element hold down bolt is sufficiently high to be compressed by the cover. 9) Fasten the covers uniformly. 10) Close the valve if provided and follow OPERATION procedures. 7.6 TROUBLESHOOTING Problem Possible Reason Remedy Strainer leaks at gaskets Damaged gasket Replace the gasket Internal / External Corrosion Strainer material not compatible with the fluid Evaluate for compatibility and replace the strainer with a compatible one.

Ensure that the unit is stable and secure, hold the Strainer firmly and loosen cover nuts. Remove the element and gaskets from the strainer body / cover using appropriate safety precautions. Once a Strainer has been disassembled, all gaskets must be disposed of since they are permanently deformed by compression during service DO NOT under any circumstances reuse gaskets previously in service, since they can cause leaks or high stress points resulting in leakage.
Page : Page 15 of 19 8.2 REASSEMBLY Refer to the exploded view for component identification, assistance and position 1) Thoroughly clean the element if a new replacement is not envisaged. 2) Place the element in the cavity provided such that it rest firmly on the cavity 3) Carefully remove the gasket from the shipping package and place in a safe area. 4) Clean any material from gasket seating cavity. 5) Place new gasket in the gasket-seating cavity. 6) Place cleaned/new element in basket pipe. Care must be taken to assure that basket ellipse ring rests squarely on the elliptical retaining ring welded in the basket pipe 7) Ensure that the element hold down bolt is sufficiently high to be compressed by the cover. 8) Locate the gasket cavity of the cover plate and place the cover plate over the body. 9) Apply oil or anti seize to threads and screw the nuts to the bolts 10) Tighten bolts and check through the connection openings that the element is located correctly and is fit tight under bolting loads. 11) After 24 hours in service relieve pressure or vacuum, drain the strainer and allow it to return to ambient temperature. Re-tighten the nuts once again. DO NOT re-tighten a Strainer while under pressure. A Strainer in service must be freed of all pressure or vacuum, allowed to reach ambient temperature and be drained or purged of all fluids before re-tightening 9.0 TELEPHONE ASSISTANCE If you are having difficulty with your FLOCLEAN Basket Strainer, notify your local C - TRU distributor or call us direct on + 91 22 32963546 /65081035.
