Uniplug or OR pipe 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
