Pipe bending is a technique used in various metal forming processes with the aim of increasing the fabrication capabilities of plumbing fixtures. The pipe can be bent at varying angles and in different directions. The simplest curve turns the tube at an angle of 90 degrees forming an elbow. Besides, pipe bending can be done in several other geometries that include 2D and 3D dimensions. There are four primary processes that fall under the tube bending category: heat induction, press bending, roll bending, and rotary bending. The process used depends on how thick the metal is, its size, and several other factors relating to the material being shaped. For example, rotary bending is often used to create straight tubes or pipes, like car frames, cages, and rails. Comparatively, when the material needs to take on the form of a coil, roll bending is used.
