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 China's steel
pipe industry and energy construction.Medium frequency pipe
expander 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.Specification: 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 intermediate frequency tube expanding machine mainly includes:
the frame, the main oil cylinder support plate(including the main
oil cylinder), the movable push plate, the front support plate, the
automatic feeding mechanism, the cutting roller table, the mold
support, the intermediate frequency coil adjusting frame (including
the intermdiate frequency heating coil), the intermediate frequency
power supply, the electrical control system and so on.
