Induction Bending Steel

How We Use Induction Bending For Metal And Steel Pipes And Tubes

The induction bending process

Induction bending (also known as "hot bending" and sometimes as "hot rolling") happens when heat is applied to a specific area of a metal tube or steel pipe, usually with the use of an induction coil, in order to make the material easier to bend to a preset radius. People often refer to this as hot induction pipe bending.

The steel is heated to between 800 and 2,200 degrees Fahrenheit and while the steel is still hot, pressure is applied to form the bend. The steel is then quenched with either air or water spray.

Advantages of induction bending

The advantages of induction bending include:

• The ability to heat a specific area of the steel pipe will ensure a minimal amount of distortion occurs after the bend is completed.
• Induction bending results in higher energy efficient systems since the power required to create the bend is kept to a minimum.
• With the induction bending process, sand filling and internal mandrels are not required.
• Bending times do not take as long as other processes, making induction bending more cost effective.
• And finally induction bending eliminates the need for mechanical or welded joints, resulting in a smoother finish.

Induction Bending Applications

Almost any metal or steel product can be used in the induction bending process; this includes metal bars, pipes and tubes. Typically induction bending is used on large pipes such as petroleum pipelines, but can also be used in making smaller products such as springs, and farming tools.

Induction bending. Hot rolling. What's the difference?

Hot rolling is a metalworking process that is used to form thinner pieces of metal by using heat. This process is mainly used to change the shape and thickness of a metal. The metal is heated to its upper critical temperature and then manipulated by a controlled amount of weight that will change the metal to the desired size or thickness. Most non-ferrous metals, these are metals other than iron or alloys that do not contain a certain amount of iron, are typically cold rolled whereas steel is usually hot rolled.

The hot rolling process

Steel slabs or billets are first heated to an extreme temperature, which is slightly above the metal's recrystallization temperature, and then they are sent through rollers that can be programmed to apply a controlled amount of pressure to form the metal into the desired size or thickness.

Hot rolling applications

Steel that has been hot rolled is typically used for sheet metal and comes coiled. These coils of sheet metal are either used directly by fabricators or as feed for cold rolling mills.
