The equipment mainly includes: machine base, main oil cylinder
support plate (including main oil cylinder), movable push plate,
front support plate, automatic feeding mechanism, blanking roller
table, mold support, intermediate frequency coil adjustment frame
(including intermediate frequency heating coil), intermediate
frequency power supply, electrical control system and so on.
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.With the utilization and
development of energy from solid (coal), liquid (oil) to gas
(natural gas), it is suitable for the steel pipe demand of energy
transmission pipeline.Has formed a complete hot - expanding steel
pipe processing industry.
