High Light PLC Control System 3LPE Coating Pipe Production LineAutomatic Operation 3LPE Pipe Coating Machine50-100 Years Service Life 3LPE Anti-Corrosion Coating Line

Product Introduction

The three-layer polyethylene (3LPE) coating process consists of:

  • First layer: Fusion Bonded Epoxy (FBE)
  • Second layer: Adhesive (AD)
  • Third layer: Polyethylene (PE)

This three-layer structure provides excellent corrosion protection for steel pipes and can extend pipeline service life from 5–10 years to 50–100 years.

It is widely used in:

  • Oil and gas pipelines
  • Urban gas transmission pipelines
  • Water supply pipelines
  • District heating projects

The 3LPE coating features:

  • High mechanical strength
  • Excellent electrical insulation
  • Strong resistance to moisture, chemicals, and environmental aging
  • Long-term anti-corrosion performance


Product Parameters

Coating Structure & Thickness

  • First layer: Fusion Bonded Epoxy (FBE) ≥ 100 μm
  • Second layer: Adhesive (AD) 170–250 μm
  • Third layer: Polyethylene (PE) 2.5–3.7 mm

Applications

The production line is widely used for steel pipe external anti-corrosion coating in:

1. Oil pipelines
2. Natural gas pipelines
3. Water supply pipelines
4. District heating pipelines
5. Chemical and industrial pipelines
6. Underground buried pipelines
