What is induction bolt heating?

By utilizing induction, bolts can be expanded faster and more efficiently than with flames or resistance heating. The bolt is inserted into a special coil with induction. The bolt is then induced with a controlled, rapid, and localized amount of heat. It is easy to remove the nut when the bolt has been heated to an exact, predetermined length.

What are the advantages of induction bolt heating?

It is very accurate to deliver heat using induction. It is impossible to heat the threads of nuts with bolts because the heat is generated within the component, so the threads keep their cool temperature during the heating procedure. The heating process is so rapid that there simply isn’t enough time to transfer heat to the threads. Lastly, induction heating does not cause rods to melt in bolts, which is a common and time-consuming problem with other methods..

By using quick-release coils, operator productivity is increased as well. Different coils of different sizes and shapes can be attached to the handheld transformers in just a few seconds.

During bolt expansion, safety is paramount in order to achieve a consistent result and avoid damaging the bolt or the personnel. Avoid all flash-over between the coil and work piece since high-energy currents can deteriorate the metal structure inside. Flash-over situations are triple-safety with glass fiber insulation holster, lacquer varnish and electronic coil-to-workpiece detection.

Where is induction bolt heating used?

A high-pressure turbine, a chemical plant, and an oil and gas processing plant use induction heating for bolt expansion.
