Uniplug or OR stoppers

On the first hand, Operators greatly appreciate uni-plug stoppers when they are called upon to intervene in pipelines on nuclear sites. These low-pressure inflatable stoppers are effectively capable of preventing any foreign objects from falling into pipelines. These stopper systems are a safeguard against FME risks that could pose a threat in nuclear installations (Foreign Material Exclusion).

Uni-plug inflatable stoppers come in a wide range of stopper dimensions. This range of stoppers includes a wide selection of dimensions, from a minimum stopper diameter of 40 mm up to a maximum of 5000 mm.

And secondly, these low-pressure stoppers can also be used for:

pipeline repairs
insulation for argon welding
mine-shaft stoppers
or chimney stoppers

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.

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 ...).

Maintenance tip

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.
