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 provides reliable and long-lasting corrosion protection for pipelines operating in demanding environments.

The coating system produced by this line consists of three functional layers:
Base Layer: Fusion Bonded Epoxy (FBE) powder coating is applied directly to the steel pipe surface, forming a strong bond and delivering excellent corrosion resistance.
Middle Layer: A copolymer adhesive layer with functional groups is used to firmly bond the epoxy base layer with the outer polyethylene layer, ensuring structural stability.
Outer Layer: High-density polyethylene (HDPE) is extruded as the outer protective layer, providing strong mechanical protection, low water absorption, and outstanding resistance to environmental factors.
Through this advanced three-layer coating process, the production line ensures uniform coating quality, improved pipeline durability, and a significantly extended service life.

In addition, the production line can efficiently apply epoxy powder coatings to both the internal and external surfaces of steel pipes, providing comprehensive anti-corrosion protection. The coated pipes exhibit excellent resistance to chemical corrosion and can withstand exposure to a wide range of aggressive media. The smooth coating surface also reduces friction during fluid transportation, improving pipeline efficiency.
Thanks to these advantages, epoxy anti-corrosion steel pipes produced by this system are widely used in oil and natural gas transmission pipelines, municipal water supply networks, drainage systems, and various industrial pipeline applications.

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.
