I. Anti-corrosion Structure and Process

Coating Structure

• Single-layer FBE: Epoxy powder is applied by electrostatic spraying and cured at high temperature to form a dense coating of 0.3–0.5 mm, with adhesion strength > 5 MPa.
• Double-layer FBE (2FBE): Primer anti-corrosion layer (≥ 400 μm) + wear-resistant top layer, with a total thickness of 600–800 μm, suitable for high-wear environments.

Composite Structure (TPEP)

• Internal wall: FBE coating (≥ 0.4 mm)
• External wall: 3PE structure (epoxy layer + adhesive layer + polyethylene layer)
   
  to achieve double internal and external protection.

II. Core Performance Advantages

• Corrosion Resistance: Resists strong acids and alkalis in the pH range of 1–14; no rusting after > 3,000 hours of salt spray test.
• Mechanical Strength: Resists soil stress, suitable for geologically unstable areas.
• Environmental & Safe: Certified as food-grade in accordance with GB/T 17219, applicable to drinking water pipelines and food industry pipelines.
• Temperature Adaptability:
  • Standard type: -30 ℃ ~ 100 ℃
  • Nano-modified type: withstands long-term high temperature up to 150 ℃ (for oil and gas transmission)
