Pipe layers bevel pipe for a variety of reasons. Plumbers and excavators bevel the ends of PVC and CPVC pipe in order to ease the coupling of fittings. Welders bevel steel pipe to provide a seat for a welding bead. Workers have the option of beveling with a hand file, a grinder or an automatic beveling machine. Regardless of the means utilized, the method remains constant. The two critical aspects of a proper bevel are angle and depth.
Things You'll Need
- Grinder, file or beveling machine
- Speed square
Fold a towel width-wise several times. Wrap the pipe with the towel. Place the pipe in the work bench vice. A beveling machine does not require a towel; simply put the pipe on the rollers or in the pipe cartridge and tighten it down. If you are using a beveling machine, twist the degrees of angle knob until it is set at the angle you require. If you are using a bench vice, place the speed square on the end of the pipe.
Place the grinder or file next to the speed square with one edge of the grinding wheel on the end of the pipe. Adjust the angle of the grinder's wheel until the marks on the speed square indicate that you are at the required angle. Make a visual mental note of this angle so you can bevel the pipe correctly once you remove the square.
Lower the grinding wheel of the beveling machine down to the end of the pipe, turn the machine on and grind the pipe as it rotates on the rollers until it is at the depth your bevel requires. Grind or file the top 1/4 of the pipe with a grinder or a file, loosen the vice, rotate the pipe 25 percent and file or grind the end of the pipe again. Continue to rotate the pipe until the entire end is beveled.
