Spiral steel pipe is the strip or coil by spiral bending forming, with double-sided submerged arc welding of internal and external seam welded spiral steel pipe, which can be widely used in water, electricity, chemical other industries in the production.
1) As long as the forming angle is changed, it is possible to produce steel pipes of various diameters with the same width of strip steel, which is easy to adjust.
2) Because it is a continuous bending shape, the length of the coil length is not limited, the length can be arbitrarily set.
3) Spiral weld evenly distributed throughout the spiral pipe circumference, so the spiral pipe size and high precision, strength is also strong.
4) Easy to change the size, suitable for small batch, multi-species spiral tube production.
