Pronal High Pressure Stoppers

PRONAL “OHP & OPV” stoppers can be used for the closure of lines of all types.

This range of stoppers allows the execution of leak-tightness controls, and the conduct of operational maintenance, both onshore & offshore. Pronal Stoppers can also be used for the flotation of jackets or pipes. They can also be applied for the execution of weld tests, repairs, or the replacement of valves in pipes.

High Pressure Pipe Stoppers

If the standard sealing pipe can not be used due to high back pressure, then these high pressure pipe stoppers are recommended.Higher operational pressure is ensured by the special Kevlar reinforcement used in all the stoppers. The diameter of the standard product line ranges from 50mm - 600mm.Stoppers must be fully inserted into the pipe prior to inflation and must not be used in pipework within open excavations or unrestrained pipework. All pipes must be anchored before pressure testing.
