Pipe bending is the umbrella term for metal forming processes used to permanently form pipes or tubes. One has to differentiate between form-bound and free form-bending procedures, as well as between heat supported and cold forming procedures.
Form bound bending procedures like “press bending” or “rotary draw bending” are used to form the work piece into the shape of a die. Straight tube stock can be formed using a pipe tube bending machineor we can also say pipe tube bender to create a variety of single or multiple bends and to shape the piece into the desired form. These processes can be used to form complex shapes out of different types of ductile metal tubing. From simple to complex bending can use manual type, NC pipe benderor CNC tube bender.Pipe bending or tube bending simply refers to the process of modifying metal pipes in order for them to achieve a certain angle or direction. The metal pipes can be defined as iron,metal,steel, cooper, brass,stainless steel,aluminum and others. Different capacity of bending machine can be work on different pipe size as 1 inch,2 inch,2.5 inch,3 inch and so on... The different types of pipe bending methods may differ from the machine used as well as the primary mechanism to achieve the bent shape.
Free form-bending processes, like roll-push bending, shape the work piece kinematically, thus the bending contour is not dependent on the tool geometry.
There are generally four (4) different methods of tube/pipe bending that can also be classified according to complexity. You’ll encounter the following: compression bending, rotary draw bending, roll bending, and mandrel tube bending. Each of these processes achieves a precision bending in order to make the pipe suitable for application, depending on the purpose.
