The Steel Pipe PE O-Type Extrusion Anti-Corrosion Coating Machine is a complete production system designed for 3LPE, 2LPE, and FBE anti-corrosion coating applications on steel pipes. The line integrates steel pipe conveying, shot blasting and derusting, dust collection, intermediate frequency heating, electrostatic epoxy powder spraying, PE and adhesive extrusion coating, water cooling, pipe end trimming, hydraulic and pneumatic systems, detection systems, and PLC intelligent control.

The O-Type extrusion coating process provides excellent resistance to chemical media such as acids, alkalis, salts, and oxidizing agents. This significantly improves pipeline service life and ensures stable operation in harsh environments. The coated steel pipes are widely used in oil and gas transmission pipelines, municipal water supply systems, drainage systems, and industrial pipeline engineering.

• Oil and Gas Transport: Used for long-distance transportation of oil and natural gas, ensuring safe and stable delivery.
• Municipal Water Supply: Applied in urban water supply systems to ensure clean and reliable water transportation.
• Drainage Systems: Used in sewage and drainage pipelines to prevent corrosion and leakage.
• Agricultural Irrigation: Used in irrigation systems to ensure efficient water distribution.
• Cable Protection: Used as protective conduits for optical fibers and power cables to prevent external damage.
• Construction Applications: Used in building water supply and drainage pipeline systems.

These pipes are widely favored for their strong corrosion resistance, high durability, and stable performance in different environments.
