pipe expanding machine for producing 630 diameter carbon steel
elbow
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.

Special equipment for steel tube hot hole enlargement, mainly for
domestic large diameter steel pipe production cannot meet the
demand of market and all kinds of steel pipe specification is not
complete, meet the needs of small batch more varieties of steel
pipe production, can satisfy the different material steel pipe hole
enlargement and various non-standard steel tube expanding needs, is
currently the main production process of large diameter steel
pipe.It has been widely used in military industry, power plant
construction, aerospace industry and Marine industry equipment
manufacturing industry,making a great contribution to the steel
pipe industry and energy construction.
