Pipes and tubes are usually measured by the outside diameter dimension – or OD. One might think that a 2.0 inch OD tube would measure 2.0 inches and a 6.5 inch OD tube would measure 6.5 inches. However, machines today cannot hold dimensions precisely to the nominal value, and because of that there must be acceptable degrees of variations. In other words, every dimension on a blueprint is subject to variations from the nominal value and so is “roundness”. But “out of roundess” measurement can be contained.
Unequal angle bending machine ( angle flange bending machine) and angle rolling machine are two names of the same machine Unequal angles are often used in tank stiffeners, matching flanges, curved lintels, hand rails, lagging rings, form work and fabricated roof trusses.
Bar bending machine ( Bar rolling machine) can also be called the flange bending machine. The sturdy body of the BIT series profile bending machine has a strong section bending capacity and provides reliable bending services.
Angle bending machine (also called angle roller) is actually just a function of section bending of profile bending machine.
Angle bending machine can roll the Equal Angle or Unequal Angle, and the angle steel after processing still keeps the two sides of the angle steel perpendicular to 90° without flanging. And there are no wrinkles.
Many Chinese customers refer to the flat steel bending machine as a flange roll forming machine. For BIT, it is just an ordinary section bending machine for bending flat steel.
Sturdy body and strong section bending ability, BIT section bending machine can bend higher strength stainless steel bar like flat iron bar.
\In the picture, the BIT section bending machine uses the function of a tee bending machine, and it is bending a high-strength stainless steel tee.
A quicker and more effective way to straighten tees is with a BIT serise section bending machine (also called a “profile bending machine,” or an “section bender.”). The curved steel tee is run through large rollers with smaller calibrating rollers until it is straight.
BIT’s special square tube rolling machine (Tube roller bender) has a combined profile section bending die, which can easily bend square tubes of any material.
The BIT series profile bending machine (pipe bending machine) allow the best profile feeding and the highest driving torque of any competitive machine. A winning combination for those looking for performance of the highest level.
From the tightest bend to the broadest, BIT serise pipe bending machines’s bending processes produce little to no distortion or ovality.It work with almost all grades of carbon steel pipe and aluminum pipe. We can bend full and half pipe with equal quality and precision.
In the past 30 years, due to the rapid development of China’s economy, about 20% of the machines we produce are used for flange forming, especially large flange forming that is difficult to mass produce.
For example, W24S-400, the factory manager once released a video to promote its large flange, the excitement can be felt across the screen.
BIT serise tube rolling machine (also called a “profile bending machine,”“Tube roller bender,” or an “tube bending machine.”) capabilities and equipment to provide square tube bending services on a complete range of materials, including aluminum, carbon steel, carbon stainless duplex steel, copper, titanium and exotic metals. No section is too small or too large for us to handle; we can manipulate square tubes of any size into custom-specified, flawless finished products with extremely tight tolerances.
