Spiral Weld-pipe Mill Tube Mill Line Steel Pipe Making Machine

Spiral welded pipe unit：

The spiral welded pipe unit is a steel pipe formed by rolling low-carbon carbon structural steel or low alloy structural steel strip into a pipe blank through a forming machine at a certain forming angle, and then using a submerged arc welding machine to weld the spiral pipe seam together. Its advantage is that it can produce large-diameter steel pipes using narrower strip steel.

The spiral welded pipe unit can spiral coil the cylindrical pipe body of the strip steel, which is welded by automatic welding equipment. The forming angle is calculated based on the strip steel width, thick wall, and pipe diameter to adjust the position of each forming roller.
