Turnkey 3LPE/FBE External Coating Plant for Oil & Gas Steel Pipes

Qingdao Huashida Machinery Co., Ltd. specializes in next-generation 3PE / 3LPE / 2PE steel pipe coating systems designed to deliver maximum corrosion protection for pipelines. Our advanced production line integrates precise surface preparation, efficient extrusion coating, and intelligent control technology to ensure stable performance and long service life. Widely used in oil & gas, water supply, and district heating projects, Huashida's coating solutions provide reliable protection even in harsh environments, helping global clients build safer and more durable pipeline networks.
This advanced coating system is designed to apply high-performance anti-corrosion layers to steel pipes used across a wide range of infrastructure projects, including district heating networks, oil and gas transmission pipelines, and water supply systems. The equipment supports flexible coating configurations, allowing it to adapt to diverse project requirements, such as:

• Fusion Bonded Epoxy (FBE)

• 2-layer Polyethylene (2PE)

• 2-layer Polypropylene (2PP)

• 3-layer Polyethylene (3PE/3LPE)

3-Layer PE Coating System Composition:

1. Primer: Fusion Bonded Epoxy (FBE) base coat

2. Intermediate: Specialized adhesive layer

3. Outer protection: High-density polyethylene sheath
   

As the most advanced protective solution for underground piping systems, three-layer polyethylene coating provides:
✓ Enhanced mechanical strength
✓ Superior electrical insulation
✓ Excellent waterproof properties
✓ Outstanding wear resistance
✓ Long-term anti-aging performance

This technology has become the industry standard for corrosion protection in:
• Oil & gas transmission pipelines
• Urban gas distribution networks
• Municipal water supply systems
• Various fluid transportation infrastructure
