EXPANSION SEAL TECHNOLOGIES DC2674 05/00 PAGE 1 OF 4 STANDARD 10-24 HIGH LIFT FLANGE WELD TEST PLUG OPERATING INSTRUCTIONS These operating instructions give step by step instructions on the use of the High Lift Flange Weld Test Plug. These plugs can be used in two different configurations as a testing plug and a welding plug. The test plug configuration allows the flange to pipe weld to be tested after welding. The weld plug configuration aids in the welding of the flange to pipe while monitoring upstream pressure and also allows the weld to be tested after welding. Follow steps labeled TP for test plug configuration, WP for weld plug configuration and TP WP for both. WARNING! PRESSURE TESTING IS INHERENTLY DANGEROUS. STRICT ADHERENCE TO THESE OPERATION INSTRUCTIONS AND INDUSTRY SAFETY PRACTICES COULD PREVENT INJURY TO PERSONNEL. ALL PERSONNEL MUST BE CLEAR OF TEST PLUG WHEN PRESSURE TESTING. FOR SAFETY, AN INCOMPRESSIBLE LIQUID SUCH AS WATER SHOULD BE USED AS THE TEST MEDIUM, RESIDUAL AIR OR GAS IS TO BE EVACUATED FROM THE PIPE PRIOR TO TESTING. PRIOR TO USE: Verify marking on seal with o-ring and replacement washer is equivalent to the pipe size being tested. They should be marked with the flange size and pipe schedule. The seal and the washer OD is sized approximately ½ smaller than the pipe ID. Replacement washers are required on all sizes except the smallest schedule available. The following sizes do NOT have replacement washers. 10 schedule 100, 12 schedule 80, 14 schedule 140. 16 schedule 120, 18 schedule 120, 20 schedule 100 & 24 schedule 120 Inspect the raised face (gasket surface) of the Flange Plug and mating flange to be tested. Damage or surface imperfections may result in leakage and should be repaired prior to testing. Clean and dry the pipe ID. Remove all moisture, debris and excessive scale. STEP 1 TP ATTACHMENT OF TEST PLUG TO MATING FLANGE Any weld droop or spatter that protrudes into pipe id more than the clearance listed in table 1 must be removed to allow plug installation. Apply gasket to mating flange face and position Flange Plug against mating flange. Rotate plug as required locating purge vent at highest point and installing flange bolts. Tighten bolts in a cross-like pattern to properly seal the flange gasket. WP ATTACHMENT OF WELDING PLUG SET-UP TO MATING FLANGE Locate the flange to be welded on the pipe using an alignment tool (The Flange Test & Welding Plug is not designed to support or position flange to be welded). Apply gasket to mating flange face and insert the Flange plug into the flange and pipe with the inert gas purge ports oriented at the top and bottom of the flange. Tighten bolts in a cross-like pattern to properly seal the flange gasket. STEP 2 TP WP TIGHTENING AND EXPANSION OF SEAL ELEMENT Correct Tightness of hex nut is critical to the operation of the Flange Test & Welding Plug, a leak of the seal is usually an indication the hex nuts were not adequately tightened. The normal torque listed in table 1 should be adequate for most installations, however due to variations within pipe ID finishes the torque may need to be increased up to the maximum torque value listed in table 1. If at the maximum torque the plug still leaks, verify the correct seal and washers are being used. Verify that the seal O-ring is seated correctly in the groove on seal and that the O-ring is not damaged, (10 and 12 plugs only). Tighten hex nuts in a cross-like pattern in approx. 100 ft/lbs increments using an impact wrench until torque specified in Table 1 has been reached. Verify this torque with a calibrated torque wrench. Remove the purge plug closest to highest point. Connect hydropump to fill port on Flange. Slowly begin to fill the plug until water flows from the vent. Discontinue water input and install plug leak tight. STEP 3 WP PREPARATION FOR WELDING Make connection to upstream monitor port that will clearly indicate an increase of pressure or the presence of dangerous gases. In addition upstream vapors may be vented by attaching approximately 50 ft. of hose to the vent port and locating the end of the hose downwind from the weld area. For normal conditions where Inert Gas Purge is not required: Remove pipe plugs from fill and vent plugs on the flange or make connections to fill and vent ports as required by welding safety procedures. If Inert gas purge is required:

EXPANSION SEAL TECHNOLOGIES DC2674 05/00 PAGE 2 OF 4 Remove pipe plugs from the fill and vent ports on the flange. Connect Inert gas supply to fill port. Make connections to vent port as required to monitor or regulate the flow of inert gas. Initiate Inert gas purge and adjust Inert gas pressure regulator as required to maintain a slight positive pressure during welding. As welding proceeds, adjust Inert gas flow as needed to insure weld quality. STEP 4 WP Welding NOTE: do not let the weld protrude into the pipe ID by more than the values listed in Table 1 or grinding of the pipe ID may be required for plug removal. Begin welding the flange to the pipe while monitoring upstream pressure. Stop welding immediately if the upstream pressure increases which indicates flow in the line. During welding the pipe at the seal location must not become too hot to touch by hand. Should the pipe in the seal location become too hot to touch by hand, discontinue welding and allow pipe too cool. STEP 5 TP WP HYDROSTATIC PRESSURE TEST WARNING! NEVER ATTEMPT TO ADJUST THE FLANGE TEST & WELDING PLUG WHILE UNDER PRESSURE. NEVER EXCEED THE TEST PRESSURES IN TABLE 2 Remove the vent plug. Connect hydropump to fill port on Flange. Slowly begin to fill the plug until water flows from the vent. Discontinue water input and install the vent plug leak tight. Refer to Table 2 for the maximum test pressure for the Flange Test Plug. The test pressure must never exceed the strength of the weakest component in the system being tested. Slowly introduce the test pressure. If a pressure decay test will be conducted, hold at desired pressure with pump for a minimum of 5 minutes prior to closing isolation valve. This will allow parts to settle. Continue holding the desired pressure to meet testing requirements. If pressure drops off a large amount or a leak between seal and tube id is detected, tighten the hex nut until leak is sealed. (Do not exceed max. installation torque). After the test is completed, release all pressure. Remove the fill and vent plugs to drain water. Remove all testing equipment. Loosen the hex nuts to fully relax seal. Loosen and remove hex nuts and flange mounting bolts. Withdraw the Flange Test Plug from the pipe.

EXPANSION SEAL TECHNOLOGIES DC2678 09/98 REV 3 07/99 PAGE 1 OF 6 HIGH LIFT FLANGE TEST & WELDING PLUG OPERATING INSTRUCTIONS These operating instructions give step-by-step instructions on the use of the high lift flange test & welding plug. This plug can be used in two different configurations as a test plug and a welding plug. The test plug configuration allows the flange to pipe weld to be tested after welding. The weld plug configuration aids in the welding of the flange to pipe while monitoring upstream pressure and also allows the weld to be tested after welding. Follow steps labeled TP for test plug configuration, WP for weld plug configuration and TP WP for both WARNING! PRESSURE TESTING IS INHERENTLY DANGEROUS. STRICT ADHERENCE TO THESE OPERATING INSTRUCTIONS AND INDUSTRY SAFETY PRACTICES COULD PREVENT INJURY TO PERSONNEL ALL PERSONNEL MUST BE CLEAR OF TEST PLUG WHEN PRESSURE TESTING FOR SAFETY, AN INCOMPRESSIBLE LIQUID SUCH AS WATER SHOULD BE USED AS THE TEST MEDIUM. RESIDUAL AIR OR GAS IS TO BE EVACUATED FROM THE PIPE PRIOR TO TESTING. PRIOR TO USE: Verify stamping on washer is equivalent to the pipe size being tested. The washer should be stamped with the flange size and pipe schedule. Example: The stamp 1P80 should be interpreted as 1 Sch 80 pipe sizes. The seal OD should be the same as the washer OD. Inspect the raised face (gasket surface) of the Flange Plug and mating flange to be tested. Damage or surface imperfections may result in leakage and should be repaired prior to testing. Clean and dry the pipe ID. Remove all moisture, debris and excessive scale. STEP 1 TP ATTACHMENT OF TEST PLUG TO MATING FLANGE Any weld droop or spatter that protrudes into pipe ID more than clearance listed in Table 1 must be removed to allow plug installation. If installation depth is limited in length of pipe one of the compression tubes between the flange and seal can be moved to the opposite side of the flange to reduce the distance between seal and flange. For ¾ 1 sizes the compression tube that is being repositioned must be placed between the Flange/Fill-Vent Port tube assembly and the Upstream monitor Port Tube. (See diagram on page 3) Apply gasket to mating flange face and position Flange Plug against mating flange. Rotate plug as required locating purge vent at highest point and installing flange bolts. Tighten bolts in a cross-like pattern to properly seal the flange gasket. WP ATTACHMENT OF WELDING PLUG SET-UP TO MATING FLANGE The distance between the flange and the washer and seal assembly should be approx. 12. If not check to see both compression tubes are installed between the flange and seal and washer assembly. Locate the flange to be welded on the pipe using an alignment tool (The Flange Test & Welding Plug is not designed to support or position flange to be welded). Apply gasket to mating flange face and insert the Flange plug into the flange and pipe with the inert gas purge ports oriented at the top and bottom of the flange. Tighten bolts in a cross-like pattern to properly seal the flange gasket. STEP 2 TP WP TIGHTENING AND EXPANSION OF SEAL ELEMENT Correct Tightness of hex nut is critical to the operation of the Flange Test & Welding Plug, a leak of the seal is usually an indication the hex nut(s) was not adequately tightened. The normal torque listed in Table 1 should be adequate for most installations, however due to variations within pipe id finishes the torque may need to be increased up to the maximum torque value listed in Table 1. If at the maximum torque the plug still leaks verify the correct seal and washers are being used. For Sizes 3/4 to 2-1/2 : Tighten hex nut to normal installation torque listed in Table 1 using a calibrated torque wrench. If shaft spins while hex nut is being tightened, a crowsfoot and a pipe wrench/opened end wrench must be used. (See Table 1 for crowsfoot sizes.) For Sizes 3-8 : For sizes 3 and larger, tighten the hex nut by hand to remove any slack from the parts. Then use a ¾ drive or larger impact wrench capable of producing the torque values listed in Table 1. A deep impact socket is required (See Table 1 for impact socket sizes.). The use of an impact wrench will prevent the shaft from spinning and enable the counting of turns listed in Table 1 to reach the required torque. If an impact wrench and deep socket are not available, two pipe wrenches may be used. The second is required to hold the shaft while turning the hex nut the required number of times.

EXPANSION SEAL TECHNOLOGIES DC2678 09/98 REV 3 07/99 PAGE 2 OF 6 The torque may be checked with a calibrated torque wrench and should be between the normal and maximum values listed in Table 1. NOTE: The torque required to seal plug sizes 3 to 8 is greater than the torque used to bolt up a 300lb flange when using a spiral wound metal gasket. STEP 3 WP PREPARATION FOR WELDING Make connection to upstream monitor port that will clearly indicate an increase of pressure or the presence of dangerous gases. In addition upstream vapors may be vented by attaching approximately 50 ft. of hose to the vent port and locating the end of the hose downwind from the weld area. For normal conditions where Inert Gas Purge is not required: Remove pipe plugs from fill and vent plugs on the flange or make connections to fill and vent ports as required by welding safety procedures. If Inert gas purge is required: Remove pipe plugs from the fill and vent ports on the flange. Connect Inert gas supply to fill port. Make connections to vent port as required to monitor or regulate the flow of inert gas. Initiate Inert gas purge and adjust Inert gas pressure regulator as required to maintain a slight positive pressure during welding. As welding proceeds, adjust Inert gas flow as needed to insure weld quality. STEP 4 WP WELDING NOTE: Do not let the weld protrude into the pipe ID by more than the values listed in Table 1 or grinding of the pipe ID may be required for plug removal. Begin welding the flange to the pipe while monitoring upstream pressure. Stop welding immediately if the upstream pressure increases which indicates flow in the line. During welding the pipe at the seal location must not become too hot to touch by hand. Should the pipe in the seal location become too hot to touch by hand, discontinue welding and allow pipe too cool. STEP 5 TP WP HYDROSTATIC PRESSURE TEST WARNING: NEVER ATTEMPT TO ADJUST THE FLANGE TEST & WELDING PLUG WHILE UNDER PRESSURE. NEVER EXCEED THE TEST PRESSURES IN TABLE 2. Remove the vent plug. Connect hydropump to fill port on Flange. Slowly begin to fill the plug until water flows from the vent. Discontinue water input and install the vent plug leak tight. Refer to Table 2 for the maximum test pressure for the Flange Test Plug. The test pressure must never exceed the strength of the weakest component in the system being tested. Slowly introduce the test pressure. If a pressure decay test will be conducted, hold at desired pressure with pump for a minimum of 5 minutes prior to closing isolation valve. This will allow parts to settle. Continue holding the desired pressure to meet testing requirements. If pressure drops off a large amount or a leak between seal and tube id is detected, tighten the hex nut until leak is sealed. (Do not exceed max. installation torque). After the test is completed, release all pressure. Remove the fill and vent plugs to drain water. Remove all testing equipment. Loosen the hex nut(s) to fully relax seal. Loosen and remove hex nuts and flange mounting bolts. Withdraw the Flange Test Plug from the pipe. INSPECT PLUG AFTER EACH USE Surface imperfections on the flange face should be fixed prior to further testing. Replace worn or damaged seals. Clean and dry plug prior to storage. Store these instructions with plug.

This plug can be used in two different configurations as a test plug and a welding plug. The test plug configuration allows the flange to pipe weld to be tested after welding. The weld plug configuration aids in the welding of the flange to pipe while monitoring upstream pressure and also allows the weld to be tested after welding. Follow steps labeled TP for test plug configuration, WP for weld plug configuration and TP WP for both WARNING! PRESSURE TESTING IS INHERENTLY DANGEROUS. STRICT ADHERENCE TO THESE OPERATING INSTRUCTIONS AND INDUSTRY SAFETY PRACTICES COULD PREVENT INJURY TO PERSONNEL ALL PERSONNEL MUST BE CLEAR OF TEST PLUG WHEN PRESSURE TESTING FOR SAFETY, AN INCOMPRESSIBLE LIQUID SUCH AS WATER SHOULD BE USED AS THE TEST MEDIUM. RESIDUAL AIR OR GAS IS TO BE EVACUATED FROM THE PIPE PRIOR TO TESTING. PRIOR TO USE: Verify stamping on washer is equivalent to the pipe size being tested. The washer should be stamped with the flange size and pipe schedule. Example: The stamp 1P80 should be interpreted as 1 Sch 80 pipe sizes. The seal OD should be the same as the washer OD. Inspect the raised face (gasket surface) of the Flange Plug and mating flange to be tested. Damage or surface imperfections may result in leakage and should be repaired prior to testing. Clean and dry the pipe ID. Remove all moisture, debris and excessive scale. STEP 1 TP ATTACHMENT OF TEST PLUG TO MATING FLANGE Any weld droop or spatter that protrudes into pipe id more than clearance listed in table 1 must be removed to allow plug installation. If installation depth is limited in length of pipe one of the compression tubes between the flange and seal can be moved to the opposite side of the flange to reduce the distance between seal and flange. For ¾ 1 sizes the compression tube that is being repositioned must be placed between the Flange/Fill-Vent Port tube assembly and the Upstream monitor Port Tube. (See diagram on page 3) Apply gasket to mating flange face and position Flange Plug against mating flange. Rotate plug as required locating fill port at highest point and installing flange bolts. Tighten bolts in a cross-like pattern to properly seal the flange gasket. WP ATTACHMENT OF WELDING PLUG SET-UP TO MATING FLANGE The distance between the flange and the washer and seal assembly should be approx. 12. If not check to see both compression tubes are installed between the flange and seal and washer assembly. Locate the flange to be welded on the pipe using an alignment tool (The Flange Test & Welding Plug is not designed to support or position flange to be welded). Apply gasket to mating flange face and insert the Flange plug into the flange and pipe with the fill port oriented at the top of flange. Tighten bolts in a cross-like pattern to properly seal the flange gasket. STEP 2 TP WP TIGHTENING AND EXPANSION OF SEAL ELEMENT Correct Tightness of hex nut is critical to the operation of the Flange Test & Welding Plug, a leak of the seal is usually an indication the hex nut(s) was not adequately tightened. The normal torque listed in table 1 should be adequate for most installations, however due to variations within pipe id finishes the torque may need to be increased up to the maximum torque value listed in table 1. If at the maximum torque the plug still leaks verify the correct seal and washers are being used. For Sizes 3/4 to 2-1/2 PLUG SIZES Tighten hex nut to normal installation torque listed in Table 1 using a calibrated torque wrench. If shaft spins while hex nut is being tightened, a crowsfoot and a pipe wrench/opened end wrench must be used. (See table 1 for crowsfoot sizes.) For Sizes 3-8 PLUG SIZES: For sizes 3 and larger, tighten the hex nut by hand to remove any slack from the parts. Then use a ¾ drive or larger impact wrench capable of producing the torque values listed in Table 1. A deep impact socket is required (See table 1 for impact socket

EXPANSION SEAL TECHNOLOGIES DC2682 05/99 REV 1 07/99 PAGE 2 OF 5 sizes.). The use of an impact wrench will prevent the shaft from spinning and enable the counting of turns listed in Table 1 to reach the required torque. If an impact wrench and deep socket are not available, two pipe wrenches may be used. The second is required to hold the shaft while turning the hex nut the required number of times. The torque may be checked with a calibrated torque wrench and should be between the normal and maximum values listed in Table 1. NOTE: The torque required to seal plug sizes 3 to 8 is greater than the torque used to bolt up a 300lb flange when using a spiral wound metal gasket. STEP 3 WP PREPARATION FOR WELDING Make connection to upstream monitor port that will clearly indicate an increase of pressure or the presence of dangerous gases. In addition upstream vapors may be vented by attaching approximately 50 ft. of hose to the upstream monitor port and locating the end of the hose downwind from the weld area. For normal conditions where Inert Gas Purge is not required: Remove pipe plug from fill port on the flange and make connection to fill port as required by welding safety procedures. If Inert gas purge is required: Remove pipe plug from the fill port on the flange. Connect Inert gas supply to fill port. Initiate Inert gas purge and adjust Inert gas pressure regulator as required to maintain a slight positive pressure during welding. As welding proceeds, adjust Inert gas flow as needed to insure weld quality. STEP 4 WP WELDING NOTE: DO NOT LET THE WELD PROTRUDE INTO THE PIPE I.D. BY MORE THAN THE VALUES LISTED IN TABLE 1 OR GRINDING OF THE PIPE I.D. MAY BE REQUIRED FOR PLUG REMOVAL. Begin welding the flange to the pipe while monitoring upstream pressure. Stop welding immediately if the upstream pressure increases which indicates flow in the line. During welding the pipe at the seal location must not become too hot to touch by hand. Should the pipe in the seal location become too hot to touch by hand, discontinue welding and allow pipe too cool. STEP 5 TP WP HYDROSTATIC PRESSURE TEST WARNING! NEVER ATTEMPT TO ADJUST THE FLANGE TEST & WELDING PLUG WHILE UNDER PRESSURE. NEVER EXCEED THE TEST PRESSURES IN TABLE 2 WARNING! (DO NOT EXCEED MAX. INSTALLATION TORQUE WHEN INSTALLING PLUG. REFER TO TABLE 1. Remove air from test cavity: Attach a valve to the fill port on the flange face of the plug. Attach the water supply to this valve. Fill and pressurize test cavity to at least 150 psi. Close valve. Release pump pressure and remove fill line from pump to valve. Open the valve to release the trapped air. This process should be repeated at least once before applying test pressure. Refer to Table 2 for the maximum test pressure for the Flange Test Plug. The test pressure must never exceed the strength of the weakest component in the system being tested. Slowly introduce the test pressure. If a pressure decay test will be conducted, hold at desired pressure with pump for a minimum of 5 minutes prior to closing isolation valve. This will allow parts to settle. Continue holding the desired pressure to meet testing requirements. If pressure drops off a large amount or a leak between seal and tube id is detected, tighten the hex nut until leak is sealed. After the test is completed, bleed off all pressure and disconnect pressure pump from fill port. Loosen the hex nut(s) to fully relax seal. Loosen and remove hex nuts and flange mounting bolts. Withdraw the Flange Test Plug from the pipe.

EXPANSION SEAL TECHNOLOGIES DC2682 05/99 REV 1 07/99 PAGE 3 OF 5 INSPECT PLUG AFTER EACH USE Surface imperfections on the flange face should be fixed prior to further testing.

EXPANSION SEAL TECHNOLOGIES DC2683 12/02 REV 1 06/03 PAGE 1 OF 4 ADDENDUM TO DC2678 OPERATING INSTRUCTIONS FOR HIGH LIFT FLANGE PLUGS USED AS WELD ISOLATION PLUGS WITHOUT FLANGE WARNING! PRESSURE TESTING IS INHERENTLY DANGEROUS. STRICT ADHERENCE TO THESE OPERATING INSTRUCTIONS AND INDUSTRY SAFETY PRACTICES COULD PREVENT INJURY TO PERSONNEL. ALL PERSONNEL MUST BE CLEAR OF TEST PLUG WHEN PRESSURE TESTING. FOR SAFETY, AN INCOMPRESSIBLE LIQUID SUCH AS WATER SHOULD BE USED AS THE TEST MEDIUM. RESIDUAL AIR OR GAS IS TO BE EVACUATED FROM THE PIPE PRIOR TO TESTING. CAUTION: THE SEAL ASSEMBLY, WHEN NOT ATTACHED TO A PROPERLY INSTALLED FLANGE, WILL NOT SEAL THE TEST PRESSURES PER ANSI B16.5. TO AVOID EXPULSION OF THE SHAFT AND SEAL ASSEMBLY FROM THE PIPE, DO NOT ALLOW UPSTREAM PRESSURE TO EXCEED THE VALUES SHOWN IN TABLE (2) AND INSTALL SAFETY GAG (SEE FIGURE 2). PRIOR TO INSTALLATION 1. To insure that all installation torque is transmitted to the seal, liberally spread antiseize over both sides of the hardened washer and onto the threads of the shaft. Use caution when applying the lubricant and handling the test plug after lubrication. The lubricant must not come in contact with the rubber seal or tube ID. WARNING! FAILURE TO USE ANTISEIZE MAY CAUSE AN INCOMPLETE TORQUE TRANSMITTAL WHICH WILL RESULT IN A DECREASE IN THE PRESSURE RATING. 2. Verify stamping on washer is equivalent to the pipe size being tested. The washer should be stamped with the flange size and pipe schedule. Example: The stamp 1P80 should be interpreted as 1 Sch 80 pipe sizes. The seal OD should be the same as the washer OD. 3. Complete Site safety standard checklist. NOTE: If the size of the seal/washer set is different than the pipe to be tested, contact Expansion Seal for the correctly sized set. 4. Prior to installing the flange welding/hydrostatic test plug, clean all debris from the pipe ID. For ¾ 1 Plug Sizes 5. Disassemble plug by removing jam nuts from end of plug. Remove all parts except hex nut and hardened washer. Install safety gag link, long tube and remaining parts as shown in Figure 2. Insert the plug into the pipe. Attach pipe restraint and tighten bolts on clamp to avoid slippage. Proceed with either step 8 9, or 10 below depending on plug size. For 1-1/2 8 Plug Sizes 6. Remove hex nut and hardened washer, compression tubes & flange. Install long tube and safety gag link as shown in Figure 2. Insert the plug into the pipe. Attach pipe restraint and tighten bolts on clamp to avoid slippage. Proceed with either step 8, 9 or 10 below depending on plug size. For 10 24 Plug Sizes 7. Locate the flange on the pipe using an alignment tool (The Flange Test & Welding Plug is not designed to support or position flange to be welded). Apply gasket to mating flange face and insert the Flange plug into the flange and pipe with the inert gas purge ports oriented at the top and bottom of the flange. Tighten bolts in a cross-like pattern to properly seal the flange gasket. See figure 4. Proceed with either step 8, 9 or 10 below depending on plug size.

EXPANSION SEAL TECHNOLOGIES DC2683 12/02 REV 1 06/03 PAGE 2 OF 4 TIGHTENING AND EXPANSION OF SEAL ELEMENT For 3/4 to 2-1/2 Plug Sizes 8. Tighten hex nut to normal installation torque listed in Table 1 using a calibrated torque wrench. If shaft spins while hex nut is being tightened, a crowsfoot and a pipe wrench/opened end wrench must be used. (See Table 1 for crowsfoot sizes.) For 3-8 Plug Sizes 9. Tighten the hex nut by hand to remove any slack from the parts. Then use a ¾ drive or larger impact wrench capable of producing the torque values listed in Table 1. A deep impact socket is required (See Table 1 for impact socket sizes.). The use of an impact wrench will prevent the shaft from spinning and enable the counting of turns listed in Table 1 to reach the required torque. For 10-24 Plug Sizes 10. Correct Tightness of hex nut is critical to the operation of the Flange Test & Welding Plug, a leak of the seal is usually an indication the hex nuts were not adequately tightened. The normal torque listed in Table 1 should be adequate for most installations, however due to variations within pipe ID finishes the torque may need to be increased up to the maximum torque value listed in Table 1. A deep impact socket is required (See Table 1 for impact socket sizes.) If at the maximum torque the plug still leaks, verify the correct seal and washers are being used. Verify that the seal O-ring is seated correctly in the groove on seal and that the O-ring is not damaged, (10 and 12 plugs only). Tighten hex nuts in a cross-like pattern in approx. 100 ft/lbs increments using an impact wrench until torque specified in Table 1 has been reached. Verify this torque with a calibrated torque wrench. Remove the purge plug closest to highest point. Connect hydropump to fill port on Flange. Slowly begin to fill the plug until water flows from the vent. Discontinue water input and install plug leak tight. 11. After isolation application is complete, insure all back pressure is released for pipe. 12. Relax the Seal by loosening the Compression Nut(s). Remove safety gag. Un-bolt the flange. (10 and larger) 13. Withdraw the plug from the tube end. 14. Inspect the plug for wear and replace any worn components. Re-lubricate the shaft threads and between the hexnut and mating surface as previously described. Any component, which is worn or damaged, must be replaced before attempting any further testing. Contact the factory for additional information on the replacement of worn or damaged parts. WARNING! FAILURE TO REPLACE WORN OR DAMAGED COMPONENTS MAY AFFECT THE ABILITY OF THE PLUG TO HOLD PRESSURE AND MAY CAUSE INJURY OR DAMAGE TO PERSONS OR PROPERTY IN THE TEST AREA. 15. Continue steps 8 through 14 for the number of pipes being tested. QUESTIONS? Contact EST Customer Service at any of the following locations with questions.
