Tube Bending

BIT Tube bending machine (section bending machine) provide custom tube bending services for round, square, and rectangular tubing in all sizes and materials. Innovative tube bending techniques also offer substantial savings to the customer by reducing the amount of extra material required by the bending process.

What is Structural Bending?

Depending upon your unique project requirements, Profile Bending angle bending may be performed on a variety of materials, including carbon steel, stainless steel, aluminum, titanium, and copper.

Square and rectangular steel tubing, commonly known as HSS (Hollow Structural Section) is a favorite of architects and designers, and is widely used in buildings, stadiums, canopies, and bridges.

The task of bending HSS tubing comes with its own set of unique challenges. The "Easy Way" bending of rectangular HSS steel tube, especially at minimal wall thicknesses, is prone to distortion and buckling. Innovative bending techniques combined with the in-house development of proprietary equipment ensures minimal distortion in bending.

Tube bending is a metal forming process that is used to shape pipes or tubing. Bending machines take straight tube stock and create a shape involving single or multiple bends. This allows the tubing to be formed in any fashion to fit the application’s specific needs. Round tubes are typically used for tube bending, but square or rectangular tubes can also be bent in order to meet your specific needs.

During the bending process, a tube is placed against a die, and a force is used to bend the tube to the die’s shape. Bending processes can also involve rollers for simple curves, and mandrels which are placed inside the tube in order to keep the inside from collapsing or deforming during the process. We offer rotary draw bending, roll bending and compression bending in order to give you the widest possible range of options for your project.

The differences between  Pipe Bending and Tube Bending

Applications

Agricultural & construction equipment: Ag and construction equipment manufacturers use bent tubing sections for tongue tubes, roll-over protection (ROPS), framing, discharge chutes, and tank supports.

Signs, displays & exhibits: Bent round aluminum tube is frequently used in these types of applications.

Architectural roof trusses, canopies & balconies: tube bending services have become increasingly popular in both decorative and structural architectural applications.

Tips for Bending Steel Tubes:

However, there is some troubleshooting to do when performing steel tube bending.

Bends often require achieving a tight radius. Since the outer wall of the bend becomes thinner, the result may be a distorted bend. To prevent this, using a mandrel to give support is recommended. That is also why press or ram bending is not recommended in these situations. The most adequate bending method would be mandrel bending, which is the same as rotary draw bending, but adding a mandrel to support the inside of the pipe.

Sometimes the radius we need to achieve makes the steel to exceed its elastic limits. It can result in deformation in the form of a hump or wrinkles. To prevent the formation of humps and wrinkles, it is recommended to use rotary draw bending or three roll bending.

When bending stainless steel tubes and pipes, it is important to remember that some of the stainless steels require around 50% more power for bending than carbon steels. Therefore, that the machinery must be set accordingly.
