Spiral steel pipe is a kind of spiral steel pipe which is formed by spiral bending of strip or coil plate and welded by double-sided submerged arc automatic welding for inner and outer seams.For the following reasons,it can be widely used in water,electricity,chemical industry and other industries.
1) As long as the forming angle is changed,steel pipes of various calibers can be produced with strips of the same width,which is easy to adjust.
2) Because it is formed by continuous bending,the length of helical tube is not limited and can be determined at will.
3) The spiral shape of the weld is evenly distributed around the whole spiral pipe,so the spiral pipe has high dimensional accuracy and strength.
4) Easy to change size,suitable for small batch,multi-variety spiral tube production.
The weld length of spiral pipe is longer than that of straight pipe of the same specification.Under the same specification wall thickness,the pressure of spiral pipe is larger.
