Seamless thermal steel pipe expanding machine is to expand the diameter of seamless steel pipe through the expanding technology to meet the actual needs of the product.

Seamless hot expanding steel pipe expanding machine is to expand the diameter of seamless steel pipe through the expanding technology to meet the actual needs of the product.Seamless hot expanding steel pipe adopts two-step push type pipe expanding machine to collect cone die diameter expanding technology, digital medium frequency induction heating technology and hydraulic technology in one machine.Too large caliber may be expanded by one step to reach the desired caliber, or may be expanded by two steps.Seamless thermal expansion steel pipe main standards GB/T8163-1999, GB/T8162-1999.The emergence of seamless thermal expansion steel pipe meets the needs of various enterprises for large diameter seamless steel pipe, and also fills the shortage of large diameter seamless steel pipe in China.Theoretical weight calculation formula of seamless thermal expanding steel pipe :(diameter -- radius) × radius ×0.02466 (carbon steel), (diameter -- radius) × radius ×0.02483 (alloy)

The medium frequency pipe expanding machine is mainly designed for the domestic large-diameter steel pipe production capacity can not meet the market demand and all kinds of steel pipe specifications are not complete, adapt to the production needs of small batch and many varieties of steel pipe, can meet the expansion needs of different materials and various non-standard steel pipe diameter, is the main production technology of large-diameter steel pipe.It has been widely used in military industry, power plant construction, aerospace industry and equipment manufacturing industry of Marine industry.Aocheng machinery equipment co., LTD. In addition to medium frequency pipe expanding machine, also produces cold extrusion tee machine, cold push elbow machine and other high-tech equipment, elbow machine, pipe bender, hydraulic press, etc..

Hot forming tube expanding machine

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.The main power source of the equipment is the double-cylinder or four-cylinder parallel equal-speed pusher. The valve bench of the pump station adopts the integrated form. According to the required outer diameter and length of the expanded steel pipe, the power of the medium frequency heating power supply, the thrust and stroke of the cylinder are set.

The hot forming pipe expanding machine equipment is composed of hydraulic push machine main machine, automatic loading and unloading mechanism, hydraulic pump station, pipe matching 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 hot forming pipe expander is the intelligent constant temperature system, which can effectively avoid the phenomenon of excessive 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 mould caused by too low temperature, and eliminate the unsafe factors.

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 problem that large diameter seamless steel tube can not be produced by hydraulic pipe expanding machine is solved.
