Tube bending is a steel fabrication process used to form pipes or tubing into various shapes. For some applications, tube bending involves small tubing and simple bends that are completed by hand. Larger tubing and complex bends may require manual bending machines, electric CNC benders, or sophisticated fully programmable machines that are fully automated. Tube bending can be used to create a wide variety of shapes, including circles, spirals, curves, and angles. The process is often used in the construction of steel pipes and tubing for use in plumbing, heating, and cooling applications. In addition, tube bending is also commonly used in the creation of steel furniture and other structural elements.
