Pipe sealing cushions and shut-off plugs
For shut-off of sewers, pipelines and drainage inlets. Sewers can be temporarily sealed with pipe stoppers to inspect, renovate or clean sewers and manholes.
Pipe cushions and shut-off plugs also play an important role in emergency situations, for example when contaminated wastewater or rainwater must be prevented from flowing on after accidents in order to prevent environmental damage.
Pipe stoppers are also used for leak tests according to DIN EN 1610. Here, a section of sewer is tested for leaks with air or water. EPUTEC offers not only sealing cushions suitable for shutting off, but also special test pipe sealing cushions suitable for leak testing of renovated and newly laid sewers and pipelines.
Our sealing cushions & shut-off plugs are made of expandable material (except for the conical pipe sealing cushions) and can be filled with liquid or air.
