The main reason for demagnetization of spiral welded pipes - meeting usage requirements

Spiral welded steel pipes are widely used in many industrial fields, such as oil and natural gas transmission pipelines, structural supports for buildings, and more. In these applications, the performance and stability of the steel pipes are crucial. The presence of residual magnetism may affect the operational properties of the steel pipes, such as reducing their corrosion resistance and fatigue resistance. Therefore, in order to meet usage requirements and ensure the long-term safety and reliability of the steel pipes, demagnetization treatment is necessary for spiral welded steel pipes.
