Product Description

The 3PE anti-corrosion coating production line is designed for applying a three-layer coating to steel pipes, enhancing their mechanical strength, electrical insulation, and durability. It is ideal for oil, gas, water, and other fluid transmission pipelines.

Coating Structure:
First Layer: Fusion-bonded epoxy powder (FBE > 100µm)
Second Layer: Adhesive (AD) 170 ~ 250µm
Third Layer: Polyethylene (PE) 2.5 ~ 3.7mm

Key Features:
·Enhances pipe lifespan from 5-10 years to 50-100 years
·High mechanical strength, excellent electrical insulation, waterproof, wear-resistant, and anti-aging properties
·Suitable for harsh environments and corrosive conditions
