What are the advantages and disadvantages of spiral steel tube?
At present, spiral steel pipe is widely used in our life. What are the advantages and disadvantages of spiral steel pipe?
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. It can be widely used in water, electricity and chemical industry for the following reasons:
1. Easy to adjust. As long as the forming angle is changed, steel pipes of various calibers can be produced with coils of the same width.
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 weld seam distributes evenly around the whole spiral pipe, so the spiral pipe has high dimensional accuracy and strong strength.
4. Easy to change size, suitable for small batch, multi-variety spiral tube production.
The weld seam of the spiral steel pipe is longer than the weld seam of the longitudinal welded pipe of the same specification, and the compressive resistance of spiral pipe is higher under the same specification wall thickness.
The defect of the weld of the spiral steel pipe is "oblique defect". In the course of use, the principal stress direction of the steel pipe, that is, the equivalent defect length in the axial direction of the steel pipe is smaller than that of the straight seam pipe.
The above is the advantages and disadvantages of the spiral steel pipe I introduced to you. I hope that through my introduction, I can help you better understand the spiral steel pipe.
