What are Spiral steel pipes?
The JS WUZHOU spiral steel pipes are created by spiral bending of a steel strip or a spiral plate and welded on each side by submerged arc welding. So, the pipes also r known as Spiral Submerged Arc-Welding Pipe, short as SSAW pipes. SSAW pipes r widely utilized in water, electricity, industry, and different industries for subsequent reasons.
Advantages of Spiral Submerged Arc Welded Pipes (SSAW)
- When the molding angle is modified, steel pipes of assorted diameters are often created exploitation of a similar breadth of strip steel, which facilitates the sort of transportation.
2. Since the steel strips are ceaselessly sinuate, the length of the spiral tube isn’t restricted, and also the length is often random.
3. The attachment spiral is uniformly distributed on the circumference of the spiral pipe, that the spiral pipe has high dimensional accuracy and robust strength.
4. straightforward to alter the dimensions, appropriate for little batches, a lot of styles of production screw.
Spiral steel pipes have a similar specification length as straight welded pipes, and also the wall thickness of a similar specification makes the spiral steel pipes stand up to the most pressure.
Disadvantages of Spiral Submerged Arc Welded Pipes (SSAW)
Firstly, the Spiral steel pipes weld defects r “oblique defects.”
Within the method of usage, the direction of the principal stress of the steel pipe, that is, the equivalent defect length within the axial direction of the steel pipe is smaller than the defect length of the straight pipe.
Secondly, thanks to the high property of impact toughness of the hot-rolled plate of pipeline steel, the CVN during this direction is often thrice above the CVN worth perpendicular to the rolling direction.

I can understand how a business could really benefit from getting some steel pipes in order to be more effective. Getting the right kind of materials from a professional could allow them to be more efficient. It was interesting to about how they can be more accurate with the right kind of strength when the attachment spiral is uniformly distributed.
Yes, thank you for your reply. We will use more professional steel pipe knowledge to provide customers with quality services
