Induction Bending Machine
From straight forward pipe-line bending machines to highly automated spool bending machines for the nuclear industry.
Induction bending Machine
BIT induction pipe bending machines are widely used in power plants, the petroleum industry, the chemical industry, shipbuilding, the nuclear industry, mining, the energy sector, and onshore and offshore oil and gas pipeline systems. Compared with the cold bending machine, the induction pipe bending machine only takes up 1/3~1/2 of the space and does not require custom-forming molds. It is one of the most efficient and cost-effective methods of pipe bending.
Acceptance of induction pipe bending machine customization in the following parameter ranges:
Elbows range in diameter from 2″ (50mm) to 64″ (1650mm), wall thickness over 1/8″ (3mm) to 5″ (120mm), and radii from 1.5DN/3″ (75mm) to 33′ (10,000mm).
The induction bending machine fixes the two ends of the steel profile, sets a good bending radius at one end, and keeps the other end at a constant speed. The steel profile is locally heated by an electromagnetic induction coil, and the bending is driven by a precision screw. The cooling medium is continuously cooled and shaped to the required bending angle.
It is used for all kinds of round or square steel pipes, stainless steel pipes, I-beam, H-beam, and U-channel hot bending, suitable for petroleum, chemical industry, metallurgy, steel structure, boilers, and other projects.

What is induction bending?
The induction bending process, also known as heat induction bending, high-frequency bending, or hot bending, uses inductors to locally heat steel by induction. This results in a narrow heat band in the shape to be bent. The shape is firmly held by a clamp at the desired radius, which is mounted on a free-pivoting arm. The shape is pushed through the inductor by an accurate drive system which causes the hot section to form the induction bend at the set radius. The bent part is then cooled by water, forced or still air to fix the bent shape.
Induction bending is a very effective method of section bending because it is fast, accurate, and almost error-free. The induction bending process is performed by heating a certain point of the metal profiles, which can then be bent effortlessly. It does not require any filling material, and the result of bending tends to keep deformation to a minimum. Many induction bending machines also choose this type of bending because of its sufficient energy. The heating process is the most time-consuming element of the process, after the heating process is completed, bending does not require much time at all.
Top 6 advantages of induction bending
- With induction bending there is the ability to heat a specific area of the metal pipe and this will ensure that a minimal amount of distortion occurs after the bend is completed.
- This process results in a more energy-efficient system since only a portion of the metal requires heating the power required to create the bend is kept to a minimum.
- The induction bending process does not require any sand filling or internal mandrels, so the overhead costs are much lower.
- Bending times are not as long as other processes, making this process more cost-effective.
- The overall quality of the product is better than that of cold bending, where excessive warping and wall thinning may occur.
- And finally, this process eliminates the need for mechanical or welded joints, resulting in a smoother finish.
Induction bending is an efficient way to form a bend when only a specific area of a metal tube or pipe requires bending. The specific area is usually heated with the use of an induction coil in order to make the material easier to bend to a preset radius. Induction bending is usually used to bend a specific area of a finished piece of metal, whereas hot rolling, much in the same way as cold rolling, is a process used to change the thickness of metal. Almost any metal or steel product can be used in the induction bending process, this includes metal bars, pipes, and tubes, and whilst with hot rolling processes, steel is the most commonly used metal. Most non-ferrous metals, which are metals other than iron or alloys that do not contain a certain amount of iron, are typically cold-rolled. Although there may be some crossovers in the way the finished metal products are used, induction bending is used on large pipes such as petroleum pipelines and is also versatile enough to be used in making smaller products such as springs and farming tools.
Induction bending is used for all kinds of round or square steel pipes, stainless steel pipes, and I-steel hot bending, suitable for petroleum, chemical industry, metallurgy, steel structure, boilers, and other projects.
