Tube bending and manipulation can be divided into two parts; the bending and the manipulation. The bending is usually carried out in a pipe and tube bending machine, which is a common machine tool in workshops that specialize in tubes. Those machines are often capable of some machining too. Manipulation means that the size of the tube changes, the width of the tube can either increase or decrease. This can be achieved in a press with special tools or in a tube forming machine. A common reason to manipulate tubes is to join tubes of the same size.
Tube manipulation is a process that is carried out in workshops that specialize in tube work.
