OPL pneumatic stoppers

Inflatable OPL stoppers, or pipe bladders, are designed to temporarily plug all types of pipes: concrete, steel, cast iron … They can be used in a wide range of contexts thanks to their varied diameters, including sanitation, rainwater, or waste-water systems, hydrocarbon and/or chemical pipelines.

The use of these inflatable stoppers means that the following operations can be performed in complete safety:

  • pipe repairs,
  • pipeline maintenance,
  • flow deviations,
  • air or water-tightness testing, in accordance with the NF-EN1610 Standard,
  • hydraulic testing.

These pneumatic stoppers are available in standard or by-pass versions.

Our inflatable stoppers meet our demanding in-house safety criteria thanks to their construction employing high-quality materials. Pronal is well aware of the risks that may be incurred by the use of inflatable stoppers; as such, priority is placed on the quality and performance of these products. Consequently, the OPL range has been designed to withstand a burst pressure safety coefficient of at least 3. The rubber that is used for these products also provides excellent abrasion and slip protection. Choosing the OPL range is a guarantee of working with a powerful, reliable, and highly durable product!

Composition / Advice

Pre-installation tips
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) and dry completely.
Storage advice
Store in its original case away from light, damp, and temperature variations.
