The Pipestoppers® Division of Huntingdon Fusion Techniques has released a set of literature describing its line of pipe sealing plugs and stoppers. The accessories can be used for low-pressure water or air testing of pipe systems in water, gas, oil, and other fluid industry pipe work, as well as for debris stopping during machining operations or overnight stopping for temporary closure of piping systems.
All plugs conform to British Standard BS8005 for low pressure testing and sealing of pipes. The mechanical plugs install with a wing nut that rotates on a friction-free washer to compress the two plates together, thus expanding the natural rubber ring to seal tightly inside the pipe or other chosen orifice. For high-temperature and aggressive applications, the natural rubber ring can be replaced with silicon, nitrile, or Viton® as appropriate.
