3PE Anti-Corrosion Coating

The 3PE (Three-Layer Polyethylene) anti-corrosion coating is designed to significantly extend the service life of steel pipes, increasing durability from 5-10 years to 50-100 years. This is achieved through a robust three-layer structure:

Layer Composition

  1. First Layer: Fusion Bonded Epoxy (FBE)

    • Thickness: > 100 µm
    • Purpose: Provides excellent corrosion resistance and adheres strongly to the steel surface.
  2. Second Layer: Adhesive (AD)

    • Thickness: 170 ~ 250 µm
    • Purpose: Acts as a bonding agent between the FBE layer and the outer polyethylene layer, enhancing adhesion and stability.
  3. Third Layer: Polyethylene (PE)

    • Thickness: 2.5 ~ 3.7 mm
    • Purpose: Serves as the protective outer layer, offering mechanical strength and resistance to environmental factors.

Features

  • High Mechanical Strength: Ensures durability and resistance to physical stress.
  • Excellent Electrical Insulation Performance: Prevents electrical interference and enhances safety.
  • Process Accuracy: Allows for precise application and consistent coating quality.
  • Environmental Friendliness: Complies with environmental standards, reducing impact.

The 3PE coating is ideal for protecting steel pipes in various applications, ensuring long-term performance and reliability in challenging environments.


 
Application

The three-layer HDPE stripe winding process, with epoxy powder coating as bottom layer and binding adhesive as second layer, is the widely used technique in steel pipe anti-corrosion all over the world.  The anti-corrosion steel pipe are applied in oil, gas and water supply pipelines.


Three-Layer structure of 3PE anti-corrosion pipe 
The three-layer PE anti-corrosion structure includes fusion bonded epoxy-powder bottom layer, polymer adhesive middle layer and polyethylene outside layer. The epoxy powder is a kind of thermosetting nontoxic coating, forming the high molecular weight cross-linking structure coating after solidifying, featuring good chemical anti-corrosion and high mechanical properties. Function of epoxy layer is to form continuous coating and to provide the steel tube surface with good  chemical resistance and cathodic disbanding resistance. The function of polymer adhesive is to agglutinate the epoxy layer and the polyethylene outside layer, which unites all three layers together. The polyethylene layer protects the pipe from abrasion, bump and water.
