Weld pipe roll forming machine mainly manufacture round tube, square and rectangle tube and special shapes tube, etc., the machine suits for material thickness of 0.5mm–2.0mm, also can customize as your requirement. The production line adopts advanced pass technology, PLC automatic control system, with stable operation, convenient operation and repair, and reached the advanced level in the same industry in the structure and accuracy. Equipment from the material to tube run out, the speed adjusts according to the tube specification changing.
The tube is widely used in many areas, such as:chemical engineering, medicine, winery, petroleum, food, automobile, paper-making industry, air conditioning and so on.
