Pipe Fabrication
In metal pipe fabrication, the choice of cutting disc often depends on the diameter of the pipe to be cut. For a 3/4-inch or smaller pipe, a 4 1/2-inch diameter will usually be sufficient. For a pipe of up to 2 1/2 inches, a 6-inch cutting wheel is effective, and for a pipe of up to 3 1/2 inches, a 9-inch cutting wheel is often most suitable. It’s also advisable to choose the thinnest disc possible to minimize heat and friction and to use a type 1 disc for a deeper cut unless the application imposes a particular constraint. For larger pipe often found on the pipeline, a depressed-center cutting disc provides added clearance when working at a constrained angle, and 0.045-inch disc thickness is ideal for cutting applications in fabrication yards or on the right of way for field repairs.
