Pronal - Model OPL -Inflatable 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!
