SSAW Pipe And LSAW Pipe

The main features of straight seam submerged arc welded steel pipe:
1) The steel pipe is a longitudinal seam, and both the internal and external welds are welded by submerged arc welding.
2) After the steel pipe is treated with overall mechanical expansion, the internal stress is small and evenly distributed, which can effectively prevent stress corrosion cracking, with high dimensional accuracy, and is convenient for on-site welding construction.
3) The pre-welding and fine welding processes are adopted, the welding process is stable, and the weld quality is high. The weld is easy to implement non-destructive testing on site during the production process and use.
4) The product specification range is large, and both small-diameter and large-wall thick steel pipes can be produced.
The main features of spiral submerged arc welded steel pipe:
1) The spiral submerged arc welded pipe has low equipment investment, simple production process, low operating cost, and has the advantage of low-cost operation.
2) When used in pressure pipeline projects, especially gas pipelines, necessary hardware configurations should be available, such as non-destructive testing, physical and chemical testing facilities, etc. Quality assurance measures should be strengthened and supervision should be carried out strictly in accordance with the production license.
