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.
