High frequency and high precision straight seam welded pipe production line
The high-frequency welded pipe production line is mainly used for continuous production of longitudinally welded pipes. Using high-frequency induction welding, it can not only produce round pipes, but also square pipes and special-shaped pipes that do not exceed the processing range of round pipes;
Production process: raw material-decoiler → shearing butt welding machine → storage device → forming and sizing machine → flying saw machine → straightening machine → milling machine → baler and auxiliary roller table frame, electrical control system, high Frequency welding equipment
