pipe expanding machine for producing 219 diameter alloy steel elbow
Are you still distressed about the large qty of steel pipe stocks?
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 created by Chinese non-standard equipment supplier KEYA. 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. As the best non-standard supplier of steel pipe secondary processing in the Chinese market, the company applied for the patent of thermal tube expanding in 1998.
Steel pipe technical parameters:
1) Material: carbon steel, alloy steel, stainless steel.
2) Diameter: 89-1420mm
Wall thickness: 30-150mm
3) Length: 3-24m

By the core technology of the patent-Steel Tube OD Hot Expansion, the requirements of different kinds of pipe diameters are satisfied,especially the large diameter pipes and kinds of non-standard steel pipes with different diameters , and some small batch steel pipe with various specifications. It is the main production technology to produce large outside diameter steel pipe, high pressure steam piping of power station and nuclear power plant . The expanded pipes has been widely used in the fields of military industry, aerospace industry and marine industry equipment manufacturing, which has made a great contribution to national defense and energy construction.
The equipment is used in the diameter expanding production of seamless pipe, straight welded pipe, spiral welded pipe etc.The suitable material for expansion includes: plain carbon steel, kinds of alloy steel and stainless steel.
