Damaged Underground Gas Line
Repairing a damaged underground gas supply line
GasGuys.ca Inc. were called in to repair a damaged underground gas supply line during excavations at an industrial facility. The damaged 1-1/4″ pipe was damaged during excavation. It supplies the security office with heating and and hot water. It is imperative that the following things are looked at when running underground supply lines:
Underground couplings can be added to join polyethylene lines. The “poly” lines have to be chamferred first to accept the fittings and make a proper seal. The damaged portion was cut out, 2 couplings added and a new portion of gas supply line to join them.
Here we test the repair for leaks. 15 PSI for 15 minutes is our mandated test for standard supply lines.
