Production of API 5L steel pipe expanding machine made in China
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. At present, thermal tube
expanding machine has been widely used and developed in the Chinese
market, and has been recognized by all industries.
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.
