WGYC serial pipe bending machine is to fix both ends of the steel pipe. Set the bending radius at one end, and push the other end forward to bend at a constant speed. The steel pipe is locally heated by electromagnetic induction coil. When bending, the steel pipe is driven by high precision screw rods pair and cooled continuously with appropriate cooling medium to the required bending angle. It can be used for the hot bending of various types of round or square steel pipe, stainless pipe and joist steel, and it is applicable to petroleum, chemical industry, metallurgy, steel structure and boiler etc.
