Tube bending is the term used for all metal forming processes that is used to form tubes or pipes. The pipes that are bent are used either in water lines, for handles, petroleum pipe lines, in power plants, as freeway signs and more. Today there are different processes and machines that assist us in the tube bending process. But this was not the case always.
The history of pipe and tube bending processes dates back to the ancient Chinese civilizations where they used reeds as tubes to pipe water. Even in United States hollowed out trees were used earlier in waterlines. Later in 1700’s, cast iron was used in England to form seamless pipes and all this was manually done as there were no specialized machines that could be used for the tubing process. world press machine
However all this changed in 1920’s when further innovations introduced the converter furnace process which allowed companies to produce malleable low carbon steel as well as roll them into hollow bars. Introduction of the electric arc welding technology also helped the tubing process. World War II also aided to the development of the tubing processes and industry as it was a great way to make products used in ships, automotives as well as aircraft. With introduction of newer technologies the tube bending industry received newer innovations which have helped in making tube bending processes efficient and simple. There are different machines available for different bending processes. Given below are some of the different types of machines used for tube bending today.
