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.
