What is DSAW Pipe？

DSAW pipe, full name "Double Submerged Arc Welded pipe", is a welded steel pipe widely used in long-distance transportation fields such as oil, natural gas, and water resources. DSAW pipe uses submerged arc welding process to perform double-sided welding on the inner and outer surfaces of the pipe, ensuring the welding quality and strength of the pipeline.

Features and advantages of DSAW pipe:

1. Double-sided welding:

Welding is performed on both the inner and outer surfaces at the same time, which improves the strength and sealing of the weld.

2. High-quality welds:

The submerged arc welding process uses slag to cover the weld. The weld does not come into contact with air during welding, reducing the impact of oxidation and impurities, thereby improving the quality of the weld.

3. High production efficiency:

The submerged arc welding process has a high degree of automation, is suitable for large-scale production, and improves production efficiency.

4. Wide range of applications:

It is suitable for long-distance, high-pressure transmission pipelines, especially in the oil and gas industry.
