The Pipestoppers® Division of HFT® provides a range of standard and non-standard Inflatable Stoppers for tubes, pipes, pipework fabrications and ductwork. These versatile Inflatable Stoppers are used to service a wide variety of industrial applications. As ‘overnight stoppers’, they provide a strong barrier in pipeline activities, to prevent foreign bodies entering the line during down time.
Inflatable Stoppers are manufactured with a strong internal inflatable bag covered in waterproof sewn polyurethane coated nylon for low friction and to prevent the production of static electricity or accidental sparking. Inflatable Stoppers are particularly useful when inserting into a small opening close to a job site, rather than at the end of the pipe. No high-pressure equipment is needed for inflation.
