GripTight® Test Plug

Brand: Curtiss-Wright Corporation
Request Information
Test Open End Pipe, Pipelines, Tubes and Pressure Vessels Quickly and Safely. High pressure pipe testing is safer than ever before, thanks to EST Group's GripTight® Test Plugs.

Unlike other pipe testing plugs that can loosen and eject under high pressure - even becoming dangerous projectiles - the GripTight Test Plugs actually use test pressure to seal more securely against the pipe's inner diameter.

The greater the pressure - the greater the grip! The result is safer installation, better sealing and all around safer testing.

GripTight Test Plugs provide a fast, safe and reliable solution for testing open ended pipe.

Capable of achieving test pressures up to 14000 PsiG - 960 BarG, GripTight Test Plugs eliminate the need for welding on and cutting off end caps, saving time and money on every test.

The self-gripping design uses test pressure to supplement the plug’s pressure holding capability - the greater the test pressure, the greater the grip.

GripTight Test Plugs incorporate a ported shaft for easy filling, venting and draining of the test system. GripTight Test Plugs are reusable, further reducing the cost per test.

Wear components: seals and gripper assemblies, are field replaceable.

Basic Operation:
  • Verify pipe size: Outer Diameter, Wall Thickness, and Inner Diameter; schedule, and material
  • Place plug into the inner diameter of the pipe
  • Tighten the Compression Nut to the required installation torque
  • Fill the pipe with the test medium
  • Pressurize the pipe, hold for the required time limit
  • Depressurize and drain test medium
  • Loosen Compression Nut and remove the GripTight Test Plug
Features
  • Pressure on Plug Squeezes Grippers Tighter; Plug can not be Ejected Under Pressure When Properly Installed
  • Have Been Used for Pipe Burst Tests in a Manufacturing Environment. Tests at Higher Pressure with Greater Safety, Typically to 80% of Yield
  • No Welding or Cutting Required. Speeds Fabrication Testing, Reducing Test Times Up to 80%
  • Reduces Seal Wear for Long Lasting Performance
  • Plugs can be Used in Solid or Ported Configurations
  • Prevents Plug Loss in Pipe End, and Eliminates Plug Lock-up After Hydro Test, Common with Inferior Plug Designs
  • Assures Retraction of Gripper Segments. Superior to O-Ring Design
  • Replacement Seals and Grippers Readily Available and Easy to Replace
  • Optional Seals: Viton®, Silicone, EPDM
  • The Self-gripping Design Provides Unparalleled Safety - the Greater the Test Pressure, the Greater The Grip.
  • The Griptight Test Plugs are Reusable. Drastically Reducing the Cost per Test By Up to 80% Compared to Welded-on End Cap
