Spiral Steel PipeThe strength is generally higher than that of straight seam welded pipes, allowing for larger diameter pipes to be produced using narrower billets, and pipes of different diameters can also be produced from the same width billets. However, compared to straight seam pipes of the same length, the weld length increases by 30% or more, and the production speed is slower, so smaller diameter welded pipes are mostly produced using straight seam welding, while larger diameter pipes are predominantly produced using spiral seam welding. The types of spiral seam pipes in our pipeline are collectively referred to as spiral seam pipes. Generally, spiral seam pipes are stronger than straight seam pipes, capable of producing larger diameter pipes with narrower billets. They can also produce pipes of different diameters with the same width billets. However, compared to straight seam pipes of the same length, the weld length increases, and production speed is slower. Therefore, smaller diameter pipes are mostly produced using straight seam welding, while larger diameter pipes are predominantly produced using spiral seam pipes. There has been a significant surge in the price of large diameter spiral pipes, and after some time, although market prices have shown a downward trend,Spiral steel pipeOur inventory is low, which will continue to drive prices up in the later stages.
