Pipe blocking, plugging and sealing for duties such as repair work, leak testing, weld purging and debris stopping 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 a variety of applications.
The Low Profile Stopper is available for applications where insufficient length of pipe is available for the regular Cylindrical or Spherical Inflatable Stopper.
Ron Sewell, Chairman at HFT® said: “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.”
“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.”
Manufactured from tough, robust fabric, these Low Profile Inflatable Stoppers are available in sizes 6 to 88” (150 to 2,235 mm) and provide excellent grip inside the pipe, with an effective airtight seal.
Each Low Profile Stopper is fitted with a standard Schrader Valve connected to a 1.2m hose, is easy to inflate using a foot pump or compressor and is heat resistant up to 90ºC (194ºF).
The Pipestoppers® Inflatable Stoppers range contains:
The Pipestoppers® Division of HFT® also provide Pipe Freezing Systems that make ice plugs inside pipes, to stop the flow of liquids so that maintenance can be carried out on valves, etc. This technique avoids the draining of a complete pipe system that might have an expensive product inside, ranging from heated water to expensive petrochemical fluids. Freezing can be carried out remotely where, for example, hazardous environments may preclude access by service personnel.
