Mid-Frequency lnduction Pipe Expanding Machine

The pipe expanding machine is especially designed for creating large diameter steel pipes by using mid-frequency induction heating technology. It is a great piece of hot expanding equipment for projects requiring steel pipes with varied diameters. It is compatible with standard and non-standard pipes fabricated from various steels, including carbon steel pipes, alloy steel pipes and stainless steel pipes.

As a great solution for large diameter steel pipe forming, the pipe expanding machine is widely used in industries such as military, aerospace, marine and power station construction. If you are looking for hot expanding solutions for seamless steel pipes, LSAW steel pipes and coil tubes, then this pipe expander is absolutely your best choice.

The mid-frequency induction pipe expanding machine is one of our patented products. It is a combination of the taper die expanding technology, mid-frequency induction heating technology and the hydraulic technology. It has been extensively used to replace the conventional drawing technique for pipe expanding, due to its rational technological process, simple structure, low power consumption, extremely low investment, stable performance and wide adaptability to pipe size and raw material.

With this pipe expanding machine, you are enabled to produce seamless steel pipes with ultra-large diameters as well as medium to large diameter welded pipes with a complete range of specifications. The expanded pipes are often used for transferring energy sources such as coal, fuel and natural gas.
