The Process Flow And Advantages of PE External Anti-corrosion Steel Pipe

The process flow of PE external anti-corrosion steel pipe: raw material inspection → steel pipe preheating and rust removal → rust removal effect inspection → steel pipe medium frequency sensor heating → epoxy powder spraying → polymer adhesive extrusion coating → polyethylene extrusion coating → water cooling → EDM inspection → pipe end processing → finished product inspection → marking and warehousing → product delivery

Advantages of PE external anti-corrosion steel pipe
1. Two-PE and three-PE anti-corrosion pipes are light in weight and have strong adhesion;
2. The coating is evenly applied and has high toughness;
3. Strong stress crack resistance and high impact resistance;
4. High sealing and strong insulation performance;
5. Strong resistance to chemical corrosion and waterproofing, and resistant to aging;
6. Good environmental protection and convenient local maintenance;
7. Strong stability; service life can reach more than 50 years.
