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.
