High pressure inflatable pipe plugHigh pressure inflatable pipe plug

High pressure inflatable pipe plugs - OHP/OPV

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, …

Composition / Advice

Care during use
Inspect the pipeline and remove any rough elements (stones, deposits …). Do not inflate the stopper when it is outside the pipeline. Never place a foreign object between the walls of the pipe and the stopper.
Maintenance tips
Carefully check all the external surfaces to ensure that there are no obvious deformations (folds, bulges, or cuts). - Clean the product (using slightly soapy water but not a detergent), rinse and dry completely.
Storage advice
Deflate the stopper after each use - Store away from a source of light - Store at room temperature with a relative humidity between 40 to 70% - Ensure that the product is protected from potentially aggressive environments (corrosive products and vapours, solvents, salt water, rodents ...).
