Most gas pipes are made of black iron, which is why they are often referred to as black pipe. Many home projects may require cutting gas pipe. It is important to follow proper procedures to facilitate cutting the pipe easily and safely. You can accomplish the task using the proper tools and procedure.
Turn off the gas supply to the section of pipe being cut by locating a shut-off valve that isolates the location. Turn the shut-off valve clockwise to shut off the gas supply. If there is no shut-off valve you can use to isolate the location, shut off the gas main at the meter. Turn the main clockwise using a medium size pipe wrench. Wait 20 minutes to allow the residual gas to dissipate.
Open the jaw on the pipe cutter fully. The cutter has several rollers on the bottom and a cutting wheel at the top. As you twist the knob counterclockwise, the roller part will detract, opening the jaw.
Place the pipe cutter squarely on the pipe in the location being cut. Ensure that the pipe is fully inserted into the jaw of the cutter.
Tighten the cutter by turning the knob clockwise. Twist the cutter around the pipe several times until you feel less resistance. Tighten the knob again and twist the cutter around the pipe several more revolutions. Repeat this process until the cutter has cut completely through the pipe.
