GripTight MAX® Test Plug

The Revolutionary Test Plug for Hardened Pipe, Non Metallic Pipe and Higher Pressures. Make Hydro Testing and Isolation Work Easy, Convenient, and Safe


  • Test pressures to 15000 Psig (1034 BarG)
  • New hardened shaft increases durability, plug life and reduces wear
  • Saves up to 80% in testing time vs. welded-on end cap testing procedures

EST Group's GripTight MAX Test Plug is a revolutionary new plug design which significantly increases the range of pipe materials and pressures that can be tested. It is highly effective in applications such as down hole / well-head piping, high pressure steam systems and in the replacement of older piping with newer high alloy hardened pipe materials used in refineries and chemical plants. It is also effective for testing non-metallic materials such as Fiberglass Reinforced Plastic (FRP) and Glass Reinforced Epoxy (GRE) piping systems.


Basic Operations

Similar to standard GripTight® plugs, GripTight MAX plugs are inserted into the pipe, (with recommended vents) and tightened to manufacturer's specifications.

The patent-pending design of the dual serrated grippers provides additional gripping points around the pipe wall to provide the strength necessary to secure the plug to meet the higher test pressure requirements.

As the pressure increases the seal and grippers are energized. This also provides the additional sealing necessary to prevent leakage. Thus as with all GripTight designs, the greater the pressure, the greater the grip!

Applications

  • GripTight MAX is designed to work up to HRC 32 Hardness, for all types of hardened pipe used in hydraulic fracking
  • Including Stainless, Chromoly, Nickel Alloy, Incoloy, Monel and Titanium
  • GripTight MAX also is excellent for testing all types of non-metallic piping systems due to its exceptional gripping power on smooth polymer pipe wall surfaces.

Features & Benefits

  • Patent-pending dual-serrated gripper design provides more gripping points on inside pipe surfaces.
  • Test pressures to 15000 Psig (1034 BarG)
  • New hardened shaft increases durability, plug life and reduces wear
  • Available for NPS ranging from 3/8” to 8” (DN10 - DN200), larger sizes up to 24” (DN 600) available on request
  • Safer and reliable testing at higher pressures
  • Effective for testing non-metallic pipe such as FRP and GRE
  • Facilitates testing in accordance with ASME PCC-2 and ASME Boiler and Pressure Vessel Codes
  • Saves up to 80% in testing time vs. welded-on end cap testing procedures
