Stoppers for oval pipelinesStoppers for oval pipelines

OVO - Stoppers for oval pipelines

Inflatable oval stoppers are used to plug oval pipelines (egg shape pipelines) and sections of pipes. These inflatable stoppers are also a perfect solution for water or air tightness testing, being compliant with the DIN 4263 and NF P16-401 standards.

These pneumatic stopper systems can also be fitted with bypass tubes. These tubes allow gas or fluids to pass through during maintenance or testing operations.

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), 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 ...).
