Hot Tapping/ Under pressure drilling on gas

Is a method of providing a branched connection with a isolating valve to a live gas pipe without interuputing the supply, avoiding any shutdowns or purging of the gas. The branch can be attached by welding or mechanical clamp, an isolation valve is then installed and a sealed drill rig attached to the valve. The pipe is then drilled while the valve is in the open position, the drill is then withdrawn and the valve closed. The drill is then removed from the valve and a blanking flange or plug fitted. The installation is completed without leakage or loss of supply. This procedoure can be carried out on Mild steel or MDPE pipe.Branch connections from 1” to 6”.
