High pressure inflatable pipe plugs “OHP & OPV” 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, Oil & Gas pipelines for inspection, test, or maintenance operations. These inflatable pipe plugs for pressure testing also ensure the buoyancy of jackets or pipes. Other uses for our high-pressure inflatable pipe plugs 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, … Detailed information Material: SBR / NPVC / EPDM depending on use Technique: hot vulcanization in a vacuum autoclave Range: OPV with 3 bar back-pressure resistance OHP 1 with 8 bar back-pressure resistance OHP 2 with 15 bar back-pressure resistance and even more upon request Dimensions: standard and tailor-made Inflation: by water Temperature resistance: -25°C/+100°C Accessories: By-pass Castor system Autonomous inflation system
