Anti-corrosion steel pipe is a steel pipe processed with anti-corrosion technology. It can prevent or slow down chemical or electrochemical reactions during transportation and use.

The cutting methods of seamless steel pipe blanks include gas cutting, shear cutting, press breaking, sawing and so on.

Straight seam steel pipes can be divided into high-frequency straight seam steel pipes and submerged arc welded straight seam steel pipes according to the production process.

The submerged arc welding process is suitable for the requirements of heavy industrial applications such as pipelines, pressure vessels and tanks, locomotive manufacturing, heavy construction, and excavation.

If the cold treatment method selected for seamless steel pipes is not correct, its performance will be affected to a certain extent. Therefore, preventive measures must be taken during the cold treatment process.

In the actual production process, these three welding forms are often intertwined. However, the solid-melt welding form is more favored by operators and used more frequently.
