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

Work flow of tube expanding machine
When expanding the pipe of the expanding machine, the movement of
the pipe adopts the translation mode, which is stable and accurate
and does not damage the pipe.This machine adopts the heating mode
of hot air circulation and is double-heating, and each heating
furnace is equipped with multi-grade heating furnace core.The
forming method adopts the qualitative method of shaping the inside
of the reaming head and adding external pressure, and the size of
the tube mouth is accurate. The machine is equipped with the
transfer switch of expanding solvent-based socket (straight port)
and expanding elastic seal ring type socket socket (R port) on the
control panel.And the R mouth is divided into the way of rising
block first and rising block after rising.The choice of tube
expanding mode is very convenient and the process is adaptable.
