OHP/OPV - High-pressure stoppers
“OHP & OPV” stoppers are capable of plugging all types of pipeline (Concrete, steel, HDPE, stainless steel…). They have been designed to withstand strong back pressures of up to 35 bars and even more on request. This is why they can be trusted to plug highly pressurized Nuclear, Onshore, Offshore & Gas pipelines for inspection, test, or maintenance operations. These pipe plugs systems also ensure the buoyancy of jackets or pipes.
Other uses for our high-pressure stoppers include welding tests, valve repairs or replacements. We can propose the production of specific stoppers that include:
• integrated flanges,
• bypass,
• specific coatings providing resistance against chemical, oil, or hydrocarbon contact,
• an automatic inflation/deflation system, …
