According to Huntingdon Fusion Techniques (HFT) locking pipes in order to carry out routine maintenance, repair work or even for weld purging is easy with Pipestoppers®.
The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® design and manufacture a range of Mechanical and Inflatable Pipestoppers® and Plugs to suit every application. Their newest addition to the Inflatable Pipestoppers® Range is the Pancake Stopper, for applications where insufficient length of pipe is available for the regular Cylindrical or Spherical Stopper.
Ron Sewell, Chairman at HFT®, commented: “With their low profile, the Pancake 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. When used in a vertical mode, these Pancake 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.”
Manufactured from tough, robust fabric, these new Pancake Stoppers are available in sizes 6 to 96 in. (150 to 2,440 mm) and provide excellent grip inside the pipe, with an effective airtight seal.
The Pipestoppers® Inflatable Stoppers Range comprises:
- Cylindrical and Spherical Stoppers: an easy way to stop the flow of gas or liquid inside pipes and ducts.
- Available up to 96” ø (2,440 mm). For higher temperatures, these Inflatable Stoppers can also be manufactured with a Heat Resistant Cover for temperatures up to 300ºC (572ºF).
- PetroChem™ Stoppers: manufactured from high-grade latex, they are used for stopping off pipes with hydrocarbon gases and liquids inside.
- Inflatable Rubber Plugs: a wide diameter range and are tough, durable, can withstand chemicals and hydrocarbons, for higher-pressure applications, with a long life.
