Induction Heating Pipe Expanding Machine

Induction Heating Pipe Expanding Machine

Are you still distressed about the large qty of steel pipe stocks?

The steel pipe expanding machine is a must-have tool for anyone who works with metal pipe. Whether you are expanding a pipe for a custom project or just creating a riser to accommodate existing pipe, the use of a steel pipe expanding machine can save you time and effort while increasing your accuracy and the quality of your work.

Many domestic and foreign steel pipe manufacturers or dealers will have a lot of steel pipe inventory, which is accumulated all year round. This quantity is not small, occupying the space of the site and affecting the return of capital, which will make many people headache. But now there is a new technology that can easily solve this problem, which is the hot-expansion steel pipe technology.

The PIPE EXPANDING MACHINE is used in the diameter expanding production of seamless pipe, straight welded pipe, spiral welded pipe and so on. The suitable material for expansion includes: plain carbon steel, kinds of alloy steel and stainless steel.

This process can expand the steel pipe of various materials from small diameter to large diameter through induction heating process, effectively solving the problem of high inventory of steel pipe for users. At present, thermal tube expanding machine has been widely used and developed in the Chinese market, and has been recognized by all industries. 

For example, if you have 219mm OD steel pipe in stock, through hot expansion, usually you can make 330mm.

Features of PIPE EXPANDING MACHINE

Short Production Time, Greater Flexibility

Traditional pipe manufacturing requires a lot of time to change out a pipe's size. As a result, large order quantities are required from the customer so that these manufacturers can see a profit.

KEYA Thermal Pipe Expansion process can change out pipe sizes in 3 hours. Shorter production time allows for greater flexibility in response to emergency order situations. It also lowers minimum order quantities to a manageable level, giving distributors the ability to carry some of those odd sizes they previously couldn't.

The production line can produce Seamless Pipe in sizes from 60mm through 1500mm OD. Wall thicknesses can be as much as 150mm thick.

FAQ: 

1) After hot expansion, will the pipe need straightening? 

Usually, short pipes are not neccessary to do straightening. Only about 5% of long pipe needs straigthening.  

2) What is the expansion rate？

The rate is 1.1-1.5 based on different material of steel pipes.
