Main features of LSAW steel pipe:

1) The steel pipe has a longitudinal weld, and the inner and outer welds are welded by a submerged arc welding.

2) After the overall mechanical expansion treatment, the internal stress of the steel pipe is small and evenly distributed, which can effectively prevent stress corrosion cracking, high dimensional accuracy, and is convenient for on-site welding construction.

3) Adopting the process of pre-weld after-welding, the welding process is stable and the weld quality is high.

4) Welds are easy to achieve non-destructive testing during production and non-destructive testing in the field during use.

5) The product specification range is large, which can produce small diameter, large wall thickness and can also produce large diameter and large wall thickness steel pipe.
