GripSafe®ST Pipe Reinforcement Device (PRD)

Highly Recommended for Use, Particularly on Thin-Walled Pipes. (ie., Schedule 10)

The Pipe Reinforcement Device (PRD), designed for pipe pressure testing, is a crucial tool that secures itself around the outer diameter of the pipe, effectively preventing expansion of the pipe wall during pressure testing procedures. Crafted with precision and durability, this clamp is engineered to withstand the forces generated during pressure tests, ensuring the integrity of the testing process. Its design enables a tight grip on the pipe, creating a seal that restricts outward expansion, thereby allowing for accurate pressure measurements. This device plays a pivotal role in maintaining the structural integrity of lower strength pipes with high ductility.

USA Industries Pipe Reinforcement Device (PRD) Shown on Pipe
For GripSafe ST ORB plugs 4" and above, 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.
