Spiral submerged arc welded pipe is a welding process used to make long steel pipes. It is commonly used in the production of transmission pipelines, oil and gas pipelines, and water pipelines, among others. The manufacturing process of spiral submerged arc welded pipe includes the following steps:

Steel plate pretreatment: First, the steel plate is pre-treated, including cutting, forming, and edge treatment, to ensure the quality of the weld.

Coiled pipe: The pretreated steel plate is rolled into a tube shape to form a steel pipe of a certain diameter.

Welding: In the process of tube coiling, automatic welding is carried out by the spiral submerged arc welding machine. During the welding process, the wire and flux are automatically fed to form a uniform weld seam.

Weld treatment: After the welding is completed, the weld is visually inspected and the internal flaw is detected to ensure the quality of the weld.

Spiral submerged arc welded pipe has the advantages of fast welding speed, high production efficiency and good welding quality, so it is widely used in pipeline engineering.
