Features include:

• Cylindrical and spherical stoppers: stop the flow of gas or liquid inside pipes and ducts. Available up to ø 2,440 mm. For higher temperatures, these inflatable stoppers can also be manufactured with a heat resistant cover for temperatures up to 300ºC.


• PetroChem stoppers: manufactured from latex, are used for stopping off pipes with hydrocarbon gases and liquids inside.


• Inflatable rubber plugs: a wide diameter range, can withstand chemicals and hydrocarbons, for higher-pressure applications, with a long life.


“The Low Profile Stopper can fit into a pipe end that may be directly on an elbow or just inside a flanged neck on a casting. Other applications include blocking pipe ends to keep gases inside or to keep debris and vermin out,” said Ron Sewell, Chairman, HFT. “When used in a vertical mode, these Low Profile Stoppers have already been used to prevent machine swarf or tools from falling into pipes, into an unrecoverable and dangerous situation, in a nuclear power steam turbine.”
