PRONAL


High pressure stopper "OHP & OPV"

PRONAL "OHP & OPV" stoppers can be used for the closure of lines of all types like concrete, steel, HDPE, stainless steel, etc.

This range of stoppers allows the execution of leak-tightness controls, and the conduct of operational maintenance, both onshore & offshore.
PRONAL solutions 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.

OHP inflatable stoppers offer numerous advantages, including a wide range of diameters, perfect leak-tightness, ease of insertion in the line concerned, rapid inflation and deployment, high resistance to wear, a minimum safety factor of 3, resistance to a counter-pressure of up to 25 bar, depending upon the application in question, or more, subject to a preliminary design analysis.

Stoppers are manufactured from an elastomer-coated fabric, vacuum-vulcanized in an autoclave.

PRONAL also designs and manufactures specific stoppers for all types of environments or applications.
