Technical Date of SSAW Steel Pipe
SSAW Steel Pipe Competitive Advantages
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.
