Production Line

The production line adopts three-roller/four-roller bending machine for forming. For the formed short pipe section, tack welding is firstly carried out by CO2 shielded arc welding, heating treatment before welding, and then internal straight welding, external straight welding, internal girth welding, and external girth welding are conducted with single wire, multi-layer and multi-pass welding. After completion of welding, the weld seam is heat preserved to reduce the weld residual stress and increase the property of stress corrosion resistance of metal. The characteristic of the production line is the wall thickness and diameter of product is large, which can be widely used for structural pipe, such as steel structural bridge, high-voltage transmission tower, sea and land wind tower, offshore platform equipment and super-long pipe piles etc.
