Used for produce diameter of 720mm carbon steel and alloy steel
pipe hot induction tube expander
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.

Specification of hot expanding steel pipe: diameter 89 ~ 1420mm,
wall thickness 30 ~ 150mm, length 3 ~ 24m.Steel tubes of various
materials can be expanded (such as p91-92 / t91-92, Q235, Q345,
45#, a106b-c, 12CrMoV).
The equipment is used in the production of seamless steel pipe,
straight seam welded pipe, coil pipe and so on.Expandable steel
tube varieties are: various carbon steel, alloy steel, stainless
steel and so on.
The patent product set cone die hole enlargement technology, medium
frequency induction heating technology, hydraulic technology in
one, with the reasonable technique, simple equipment structure, the
construction of low energy consumption, low investment, good
product quality, wide range of raw materials and products
specifications suitability, flexible variable low input of
production batch adaptability to replace the traditional steel pipe
industry tension dial hole enlargement technology, became the
resolve the shortage of large diameter seamless pipe at home and
abroad, a series of large and medium diameter welded pipe
specification is difficult to complete an important and
indispensable production capacity.
