Installation Procedure:

Warning: These are general instructions only. Please refer to the appropriate operating procedures for thetest plug being utilized. The 147 Series Test Plugs are designed to be self-sealing and self-gripping, which facilitate both the seal and the gripper to become tighter as pressure increases. The extra squeeze of the seal and gripper caused by the test pressure can be detected as minor movement of the shaft. Installing the Safety Gag with a tight chain may limit or prevent the small movement of the test plug shaft as pressure is increasing, and subsequently limit or prevent the self-sealing and self-gripping feature of our test plugs. The amount of slack in the chain as well as the position of the installed plug should be observed from a safe distance to insure no appeciable movement of the plug has occurred. Should movement be noted, the test should be stopped and all pressure released immediately.
  1. Install Safety Gag pipe clamp onto pipe being tested. Safety Gags are to be installed with some slack so that movement of the shaft is not prohibited as pressure increases during testing.
  2. Tighten bolts to insure slippage will not occur.
  3. Insert test plug into tube or pipe. Follow appropriate operating procedures for the plugs being utilized, and install plugs per recommended torque values using a calibrated torque wrench.
  4. Prior to pressurizing the system, slip the link over the shaft end. Safety Gags 8" and larger are equipped with two chain and link assemblies. The links are stamped with the shaft sizes they can accommodate. Each link can do at least two sizes of shafts. Insure you have the appropriate link set-up before using. Unscrew the chain connector and switch the link around if necesary.
  5. Continue with appropriate operating procedures.
