Plastic-Coated Anti-Corrosion Production Process

Plastic-Coated Anti-Corrosion Production Process

A plastic-coated steel pipe is a steel pipe with a polymer coating sprayed onto its surface, featuring characteristics such as corrosion resistance, abrasion resistance, acid and alkali resistance, and anti-aging properties.

3PE Anti-Corrosion Production Process

3PE Anti-Corrosion Production Process

The base pipes for 3PE anti-corrosion coating include seamless steel pipes, spiral steel pipes, and longitudinal seam steel pipes.

Spiral Steel Pipe Production Process

Spiral Steel Pipe Production Process

Spiral steel pipe is a spiral seam pipe made from strip coil as the raw material, formed by cold extrusion, and welded using the automatic double-wire double-sided submerged arc welding process.
