The traditional medium frequency pipe bending machine is rotating the pipes by rocker arm to bend pipes, and the bending steel radius depends on the movable length of the rocker radius. At present, the max pipe bending radius is about 10 meters in the market, what is more, the equipment is large and the operation is difficult. The Cold bending equipment cannot bend the pipes if the diameter is larger than 273mm or the pipe wall thickness larger than10mm. 

In recent years, as the development of aircraft terminal, the railway station, sports venues, exhibition center, large factory and other buildings, the max pipe bending radius should achieve 400 meters, but the traditional rocker arm cannot achieve, the market need  a new type pipe bending machine to bend pipes of large diameter and thick wall thickness.

In order to satisfy the market, our company and Xuzhou New era company develop the PLC control large pipe bending machine. The maximum radian can be infinite; it fills the blank in the industry. The large pipe bender is mainly used for all kinds of large steel structure workshop. We have got the national patent of this equipment.
