The first type of manual pipe bending machines are the hand-operated mechanical devices that are mainly used to bend pipes. They consist of a large drum that is covered with either leather or plastic hose and a series of levers that are pulled to the correct position by hand pressure. In general the work of a this type of machine is to straighten a pipe by making gentle tension on both ends of the pipe. This type of machine is capable of completing the task much more quickly than any other mechanical process.

The second type of machine is the automated mechanical device that consists of a large table and various other equipment that are fitted around the table, these machines are capable of completing tasks like bending long tubes and drawing complex shapes. The most important difference between these two types of machines is that while the roll bending machines are used to make decorative or artistic products, the compression bending machines are used to do serious manufacturing work. This type of machine uses pressurized air or a similar type of compressed gas to run. It requires experienced operators to control the amount of air being fed into the cylinder while it is running.
The last type of machine is the hydraulic machine that has a single cylinder and a piston that are inserted into the cylinder. When the cylinder starts rolling, a flywheel is attached to the piston and the air or gas fed to the cylinder. This type of machine is capable of both roll bending and compression bending. The hydraulic machine also has a flywheel that can be manually set. Most of the modern day air cylinder fed machines use hydraulic fluid in the air tank as opposed to the old style water cylinder.
