1. Product Definition

The 40'' 3PE Pipe is a large-diameter steel pipe with a three-layer polyethylene anti-corrosion coating, designed for critical infrastructure projects. Key features:

• •

  Size: 1016 mm OD, wall thickness 6–25 mm.

• •

  3PE Structure:

  • •

    FBE Base Layer (>100 μm): Chemical resistance & adhesion.

  • •

    AD Middle Layer (170–250 μm): Interlayer bonding.

  • •

    HDPE Top Layer (2.5–3.7 mm): Mechanical protection

• •

  Lifespan: 50 years in buried conditions, validated by accelerated aging tests

  
  

2. Key Applications

• •

  Oil & Gas Transmission: High-pressure sour gas pipelines (e.g., China West-East Gas Pipeline)

• •

  District Heating: Steam/hot water networks (150°C) in urban areas

• •

  Industrial Corrosive Media: Chemical processing plants (acid/alkali resistance)

3. Compliance & Advantages
