CUSTOMER TESTIMONIAL
"GripSafe plugs have been valuable assets on the LNGC site. The quick and easy installation, use, and removal of the plugs have made testing plain end pipe simple. The Lifting Device makes rigging of the larger plugs into position fast, convenient, and safe. The design of the grippers leave little to no marks inside the pipe. Torque values and plug info on the front plate makes plug identification and double-checking for the right plug usage easy. Overall, the GripSafe plugs are an excellent product."

42" Custom ORB Plug
(P) - When testing in ANSI A106 Grade B pipe material, a Pipe Reinforcement Device (PRD) is required if the Max Plug Back-Pressure Rating (PSI) shown in the last column of our specifications pages for plug sizes 4" and above will exceed the number identified after the "P-". If the material is not A106 B, consult USA Industries engineering team for more information.
In general, a pipe reinforcement device is strongly recommended for all pipes 10/10S and thinner walled.

With its exclusive patented design, GripSafe ST features an advanced self-gripping technology that mitigates the chance of plug ejection immediately upon insertion into the pipe, even before nuts are tightened.
The advanced system evenly distributes the load among the gripping wedges, guaranteeing optimal surface contact and secure holding. As pressure mounts behind the plug, the wedges tighten their grip. Regardless of any pipe irregularities, each wedge adjusts independently to ensure plug security and safety. Combined with its automatic gripping function, GripSafe elevates the concept of "self-gripping" to new heights.
On average, GripSafe plugs are lighter than competing products. As plug sizes increase, substantial weight disparities emerge, with larger sizes experiencing reductions of up to 50% in weight without compromising their holding capabilities.
Unlike competing products that rely on serrated jaws or sharp edges to grip the pipe, GripSafe ST features a distinctive wedge system to securely hold the plug in place, while leaving virtually no surface damage and potential need for pipe cleanup.
GripSafe plugs feature GritlockĀ®, an exclusive brazed texture on the gripping wedges suitable for any metal type without introducing carbon contamination. Unlike other plugs, GripSafe doesn't necessitate alternative parts for application in stainless steel and other alloy pipes where cross-contamination poses a concern.

Test pipe sections without the need for flanges.
Perform hydrostatic testing of pipe spools, eliminating the need for end caps and welding.
Enhance safety measures by averting exposure to hydrocarbon or other process leaks. Mitigate the potential for harm to personnel in cases of accidental valve openings, valve leaks, or other pressure equipment failures upstream.
Introduce inert gases via the vent pipe into a vessel to facilitate back-purging welds or to remove oxygen for various other processes.

A Critical Reminder: Conducting pressure testing poses significant hazards, demanding strict adherence to safety protocols. Ensure all connections, valves, flanges, and fittings are suitable for pressure testing. Verify the compatibility of line ID & Plug Range. Most importantly, never position yourself in front of a test plug or enclosure during testing. Discharge from a plug during testing could result in severe injury or fatality.
Failure to adhere to the complete installation procedures outlined in our operating manuals may lead to personnel injury and equipment damage.
