Below a brief overview of these different types. The major benefit of this method is that it provides higher accuracy, since there is no change in the final dimensions of the metal due to temperature changes.īesides this temperature-based classification of tube bending processes, the different types of tube bending can also be defined based on the technology used. The cold tube bending method does not require heating the metal tubing to a high temperature, the bending is accomplished at the room temperature of the tube. Metals at high temperatures become softer and flexible, so they don’t break and can bend with a lesser force.Ī major drawback of this method is that metals expand on heating, so the final dimensions of the bend and the angle of bend can be different on cooling than what is required. Pipe and Tube Bending Tube bending methods are mainly classified into two types - hot tube bending and cold tube bending.Īs the name suggests, hot tube bending involves heating the tube at a high temperature so the bending process becomes easier.
