The 3PE (Three-Layer Polyethylene) external coating is a high-performance anti-corrosion structure composed of fusion-bonded epoxy (FBE) as the inner layer, adhesive (AD) as the middle layer, and polyethylene (PE) as the outer layer.
It features high mechanical strength, excellent electrical insulation, stable process parameters, and environmental friendliness, and is widely used in oil and gas transportation, urban water supply, heating systems, and gas pipelines.
