Solid state high-frequency pipe production line is designed to produce welded pipes as well as square and rectangular pipes and formed sections of the corresponding size. The products conform to BS/ASTM Standard. Adopting the advantages of the equipment of the same kind at home and abroad, each element of the production line is designed with new ideas. The application of Germany technology is PLC automatic control system. It is British Eurotherm digital speed regulating unit guarantee that the production line works reliably and operates and main tams easily. Being the best inside the stare, the production line can also rival the advanced ones in the world.This is milling plant is the facility to consecutively form and weld the slit strips in horizontal direction for the desirable size. It is using high frequency induction device to mill and cut to pipe. 
This kind of machine taking the steel strip with certain width as raw material, to produce steel pipes according to requested size by cold roller forming and H.F. welding method.
