Product Description


3 Layer Polyethylene (3LPE) Anti-Corrosion Steel Pipe Production Line for Oil & Gas
The 3-layer polyethylene (3LPE) anti-corrosion steel pipe production line is designed to apply a high-performance three-layer protective coating to steel pipes. By integrating advanced coating technology with high-quality materials, the system ensures reliable and long-lasting corrosion protection for pipelines used in demanding environments.
The coating structure produced by the line consists of three functional layers:
Base Layer: Fusion bonded epoxy (FBE) powder coating is applied to the surface of the steel pipe, forming a strong bond and providing excellent corrosion resistance.
Middle Layer: A copolymer adhesive layer with functional groups is applied to firmly bond the epoxy base layer with the outer polyethylene layer.
Outer Layer: High-density polyethylene (HDPE) is extruded as the outer protective layer, offering strong mechanical protection, low water absorption, and excellent environmental resistance.
Through this three-layer coating process, the production line ensures uniform coating quality, enhanced pipeline durability, and extended service life.

Our Advantages

High Sealing Performance: The coating system provides excellent sealing capability. During long-term operation, it helps reduce energy loss, lower operating costs, and minimize environmental impact.
Outstanding Corrosion Resistance: The 3LPE coating offers strong protection against corrosion. It features a simple and efficient application process and provides a long service life of 30–50 years.
Excellent Low-Temperature Performance: The coating maintains strong corrosion resistance and impact resistance even in low-temperature environments, ensuring reliable pipeline protection.
Optimized Material Structure: By combining the high bonding strength of epoxy powder, the low water absorption of polyethylene, and the flexibility of hot-melt adhesive, the coating system achieves excellent durability and reliability.
Cost-Effective Solution: The production process is efficient and stable, delivering superior anti-corrosion performance with high cost-effectiveness while meeting international standards.

5 stars for this high-performance HDPE jacket pipe extrusion line! It works perfectly with PU foam pre-insulated pipe systems, creating strong, weather-resistant outer casing for municipal and industrial heating projects. The extruder is powerful, forming is one-time finished, and raw material utilization rate is very high. Stable continuous operation, solid mechanical design, and great cost performance. Exactly what our pipeline manufacturing plant needed.
