2. The welding seam is easy to realize nondestructive inspection in the production process and nondestructive inspection in the field during use.

3. Wide range of product specifications, can produce small diameter, large wall thickness, but also can produce large diameter, large wall thickness of steel pipe.

4. The steel pipe has a longitudinal weld, and the internal and external welds are welded by a submerged arc welding.

5. After the overall mechanical reaming treatment, the internal stress of the steel tube is small and evenly distributed, which can effectively prevent the stress corrosion cracking, with high dimensional accuracy, and facilitate the on-site welding construction.
