| Medium frequency pipe expander is a special equipment for diameter expansion
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, and has made a great contribution to the national steel pipe industry and energy construction.
Medium frequency pipe expander is applied to the thermal expansion production of seamless steel pipe, straight seam welded pipe, coil pipe and so on.Can expand the variety of steel pipe: all kinds of carbon steel, alloy steel, stainless steel and so on.
Specification of hot expanding steel pipe for medium frequency pipe expanding machine: diameter Φ60 ~ Φ1420mm, wall thickness of 3 ~ 120mm, length of 3 ~ 24m.Can be expanded to make various materials of steel pipe (such as P91-92/T91-92, Q235, Q345, 45#, A106B-C, 12CrMoV).
Medium frequency pipe expander mainly includes: frame, main cylinder support plate (including main cylinder), movable push plate, front support plate, automatic feeding mechanism, production efficiency of medium frequency pipe expander
And compared to the manual heating of the steel pipe, the medium frequency pipe expander simplifies the process, reducing the labor cost and time.Improved production efficiency.
The equipment is composed of hydraulic push machine main machine, automatic loading and unloading mechanism, hydraulic pump station, pipe device, operation table, motor control cabinet, intermediate frequency power supply, compensation capacitor, water cable, intermediate frequency coil adjusting frame, reactor and other components.One of the advantages of the medium frequency pipe expander is the intelligent constant temperature system, which can effectively avoid the high temperature and low quality of the steel pipe and scrap of the mould caused by human factors, or the fracture of the tie rod and the mould caused by the low temperature, and eliminate the unsafe factors.
Pipe expanding machine is a special equipment for hot expanding of steel pipe. It is designed for large diameter seamless steel pipe whose production capacity and specifications are not enough to meet the market demand at home and abroad.It can meet the needs of small batch and many varieties of steel pipe production, and can meet the needs of diameter expansion of different materials and various non-standard steel pipes. It is the main production technology of large diameter steel pipes at present.The main power supply of the equipment for the double oil cylinder or four cylinder parallel average pushing machine, pump valve in the form of integration, in accordance with the required to enlarge the diameter and length of steel tube, set up the power of medium frequency heating power supply, thrust and stroke of oil cylinder roller, mould brackets, intermediate frequency coil to adjust (including intermediate frequency heating coil), intermediate frequency power supply, electric control system, etc
