Product Description

Product Description

Structure Composition

The Three-Layer Polyethylene (3LPE) anti-corrosion steel pipe typically consists of three layers:

  1. First Layer (Epoxy Powder Layer): Acts as the base layer, in direct contact with the steel pipe surface, providing excellent adhesion and anti-corrosion properties.
  2. Second Layer (Adhesive Layer): Utilizes a copolymer adhesive with branched functional groups to bond the epoxy powder layer and the polyethylene layer.
  3. Third Layer (Polyethylene Layer): Employs high-density polyethylene as the outer anti-corrosion coating, offering superior mechanical protection and corrosion resistance.Three-Layer PE Coating Steel Pipe 3lpe Anti-Corrosion Pipe Coating Machine

Advantages of the 3LPE Pipe Coating Line

  • Exceptional Sealing Performance: Ensures significant energy savings, cost reduction, and environmental protection during long-term operation.
  • Strong Corrosion Resistance: Features simple and quick construction, with a service life of 30-50 years.
  • Excellent Performance at Low Temperatures: Maintains good corrosion and impact resistance under low-temperature conditions, with low water absorption by polyethylene.
  • High Anti-Corrosion Reliability: Combines the high strength of epoxy, low water absorption of polyethylene, and excellent flexibility of hot melt adhesive, ensuring high reliability of the anti-corrosion layer.
  • Simple Production Process: Offers good anti-corrosion effects at a competitive price and is globally recognized as the best pipeline anti-corrosion coating.

    Applications

    The three-layer polyethylene anti-corrosion coating serves as an advanced outer protective layer for buried pipes and is widely used in the anti-corrosion of gas and oil transmission pipelines, urban gas supply systems, water supply pipelines, and other fluid transmission pipelines. The 3LPE anti-corrosion coating enhances the mechanical properties of pipelines, offering high electrical resistance, waterproofing, wear resistance, and anti-aging performance.

    Technological Processes

    1. Pipe Loading: Place the steel pipes onto the conveyor system.
    2. Pipe Conveyance: Transport the pipes to the next process via a screw conveyor.
    3. Rust Removal: Clean the steel pipe surface to remove rust and contaminants, ensuring a cleanliness level of at least Sa2.5.
    4. Intermediate Frequency Heating: Heat the pipes to the appropriate temperature for coating application.
    5. Epoxy Powder Coating: Apply the epoxy powder layer to the steel pipe surface.
    6. Outer Layer Adhesive and Polyethylene Coating: Sequentially apply the adhesive and polyethylene layers.
    7. Cooling Spray: Cool the coated pipes to cure the coating.
    8. Pipe End Grinding: Grind the ends of the pipes to ensure a smooth finish.
    9. Pipe Unloading: Remove the processed pipes from the conveyor system.
