Working Mechanism

  • The plugs should be positioned into the pipe at a distance at least equal to the pipe diameter.
  • Connect one end of the inflation hose to the plug inflation fitting.
  • Brace / block the plug.
  • Inflate pressure to the plug through the inflation hose and let it stabilise.
  • Proceed with the testing of pipe or other use of the plug.
  • Release plug pressure from outside the danger zone until the plug is completely deflated and finally remove bracing / blocking system.
