tube bending

Tube & Pipe Bending Common Terminology

Tube is bent around a fixed radius die with a mandrel insert in to prevent it from collapsing during bending. The tube or pipe is clamped against the die and this is then rotated whilst the pressure die moves in a straight linear motion. This is the most common form of bending.

2019 Everyone should know about bending steel

Bent steel components don’t just “walk out” of the rolling mill. Bent steel members are made of straight materials and are bent by your bending company to your requirements.

The bending process does not affect the strength or structural integrity of the steel. When the shape is successfully bent without any buckling or local cracks in the steel, under actual conditions of use, the component will withstand much less stress than that associated with the bending operation. Once the bending is completed, the member can be expected to perform as needed.

tube bending

Tube 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.

Bar Bending

Because bars are solid metal, they bend very well. Bending bars is the easiest when the sections to be bent are rounds, half rounds, squares, hexagons, or rectangular, and need to be bent “the easy way.” Bending bars the easy way (y-y axis) creates a belt-like shape; bending bars “the hard way” (x-x axis) creates what looks like a giant metal washer. All else being equal, bending bars that are flat the hard way is the most difficult bar bending process.

channel bending

Channel Bending

Channel Bending easiest channel bending process is “flanges out.” “Flanges in” channel bending can be difficult if the flanges are relatively tall. The most difficult channel bending process is “the hard way”—indeed, all else being equal, the hard way is one of the most difficult structural shapes to bend without distortion. In checking the quality of “hard way” bent steel channel, it is critical to check that the flanges are square, that there has been no buckling of the web, and that the radius is true.

Structural Bending

Structural Bending

Structural bending includes rolling all types of beam, such as S beam rolling, wide flange beam rolling, M beam rolling or Junior beam rolling.

bent-I-beam

Beam Bending

There are two primary methods used in beam bending applications, informally known as the “easy way (I-Beams)” and the “hard way (H-Beams).” BIT section bending machines excels at both, that ensures even the most demanding beam forming projects are completed to industry-required guidelines.

angle bending machine

Bending Angle Iron

Rolled angle bending is a cost-effective process that eliminates sharp edges, improves strength, angle rolling delivers functional and cosmetic value for many applications.
BIT section bending machine’s Bending angle bending may be performed on a variety of materials, including carbon steel, stainless steel, aluminum, titanium, and copper to make curves, angle iron rings, angle iron flanges, angle iron pipe supports, and many other parts.

Profile Bending Machine

W24S-100 4-roll Hydraulic Profile Bending Machine

This model W24S-100 belongs to the old model of BIT, which has now been replaced by W24S-140. This is because the processing capacity of the 140 profile bending machine covers the processing range of the 100 model.
