The Pipestoppers Division at Huntingdon Fusion Techniques HFT manufacture a range of inflatable stoppers for fast, reliable and safe stopping, blocking and testing of pipes, joints, channels, inlets and a number of other uses.
An export customer required a large stopper for blocking hot fumes from a chimney stack measuring 114 inches (2,896 mm) in diameter to carry out vital maintenance and repair work.
HFT manufactured two inflatable stoppers for the client, their largest size to date.
A heat resistant cover was also required to protect and prevent the Inflatable Stopper from being damaged.
The recommended maximum temperature for this type of stopper is 90°C (194°F) but with a Heat Cover fitted this increases to 300°C (572°F).
All Inflatable Stoppers are manufactured with an internal latex inflatable bladder covered in waterproof polyurethane coated nylon fabric.
The standard range of Inflatable Stoppers available for immediate delivery are in sizes ranging from 1 inch to 96 inches (25 to 2,438 mm).
Luke Keane, technical sales manager at HFT, said: “Our Pipe Stoppers are lightweight, easy to transport and pose little risk to any personnel that may be working below, making a safe working environment.
“Using the alternative option of mechanical stoppers in this sort of diameter would involve heavy machinery to manoeuvre into place and pose some serious health and safety concerns.”
The Pipestoppers Division at HFT supplies a range of mechanical and inflatable Pipestoppers and plugs to suit every application.
