Product Features• Expandable design allows use in plugs below max size
USA Industries' Inflatable balloon pipe plugs expand to temporarily isolate pipes during repairs or in the event of a spill. Inflatable plugs are available for isolating piping in line sizes from 1.5" through 66".
The innovative design allows the isolation plug to be smaller and more flexible which means it can be snaked through hot tap or branch pipes into larger pipelines that are otherwise inaccessible. Pipe plugs can inflate up to 8 times it's compact size to prevent the flow of liquids during maintance work or to block pipes or drains in the event of a spill (connects with your air compressor). The compact size also means that this plug takes up minimal storage.
While no isolation plug is one size fits all, USA Industries' balloon plug conforms to a wide range of line sizes and can inflate fully or partially to fit your application. Inflatable plugs are available with special coatings / materials designed to resist certain chemicals and temperatures upon request. Plugs can also be made UV-resistant and have a shelf life of more than 10 years.
A SPECIAL WORD OF CAUTION: Pressure testing can be an extremely hazardous operation and safety precautions should be strictly adhered to. All connections, valves, flanges and other fittings should be checked for suitability to test pressure. Verify the line ID & Plug Range match. Most importantly - Never stand or pass in front of any test plug or other enclosure while test is in progress. If plug discharges during a test, serious injury or death could occur.
