Fast, reliable and safe stopping of pipe contents with inflatable rubber plugs

Typical applications include blocking pipes, tubes, dams, inlets, storage tanks, manholes and channels; use in water, sewage, fluid production (milk, beer, chemicals), petrochemical, pharmaceutical and gas pipeline sys- tems; restricting, diverting and bypass- ing flow during pipeline maintenance or modification; and keeping pipelines free of dirt and contaminants by capping and blocking the ends. The plugs can be floated down pipes and stopped at a desired location by holding onto the inflation hose. Huntingdon Fusion Techniques – UK

with each plug having a wide degree of flexibility in diameter. HFT chairman Ron Sewell said, “Inflatable rubber plugs are highly resistant to oils, hydrocarbons and petrochemicals. They are used during new pipeline installation or for carrying out routine maintenance and repairs. They seal off sections of a pipe quickly and safely, and are very simple to use. Inflation can be carried out almost instantly with a compressor and they can be inflated with hand or foot pumps too.” The plugs are manufactured from high- quality rubber, comprising a mix of styrene, butadiene and isoprene.

Sealing, stopping and blocking pipes where oils, hydrocarbons and petrochemicals are present can cause major inconvenience, with many normal stoppers not being able to handle such conditions. The Pipestoppers ® division at Huntingdon Fusion Techniques (HFT) manufactures a range of inflatable rubber plugs for heavy-duty applications where pipes might contain liquids and gases to which usual inflatable stoppers are not resistant. HFT’s lightweight inflatable rubber plugs can withstand temperatures from -40 to +70°C (-40 to 158°F), and are available in sizes from 51 to 1,981mm (2" to 78"),
