Flow and line stopping equipment gives the user the opportunity to isolate a section of pipeline to carry out repair and maintenance work. The Pipestoppers Division from Huntingdon Fusion Techniques HFT designs and manufactures a range of standard and non-standard Inflatable Stoppers for tanks, chambers, tubes, pipes and pipework fabrications, offering a range of pipe stopping and blocking requirements. All Inflatable Stoppers are manufactured with a strong internal latex balloon covered in a waterproof polyurethane coated nylon bag for low friction and to prevent the production of static electricity or accidental sparking. Inflatable Stoppers are particularly useful when one or more can be inserted into a small opening close to a work location, rather than at the end of the pipe, tank or vessel. No high-pressure equipment is needed for inflation.
