LSAW welded steel pipe is a spiral steel pipe made by submerged arc welding technology. Compared with other types of spiral steel pipes, it has several obvious characteristics:

First of all, the strength of double-sided submerged arc welded spiral steel pipe is higher. With the advent of submerged arc welding technology, the heat during welding is more concentrated, so that higher strength can be obtained.

Secondly, double-sided submerged arc welded spiral steel pipe has better corrosion resistance. During the production process, the welded parts of this steel pipe will be strictly protected, thereby effectively reducing oxidation, corrosion, and other phenomena on the surface of the steel pipe and increasing its service life.

Finally, the LSAW welded steel pipe has a more beautiful appearance. The surface of this kind of steel pipe is smooth and flat, with no obvious welding marks, and has high aesthetics and decorative properties.

Double-sided submerged arc welded spiral steel pipe has been widely used in many fields due to its unique characteristics. For example, it can be used for transmission pipelines in various construction projects, such as water supply, gas, etc.; it can also be used for transmission pipelines in oil, natural gas, chemical industry, electricity, and other fields. In addition, double-sided submerged arc-welded spiral steel pipes are also widely used in manufacturing machinery, automotive parts, aerospace devices, and other fields.
