3PE Anti-Corrosion Coating Line for Steel Pipes
3PE (Three-Layer Polyethylene) anti-corrosion coating is a high-performance pipeline protection system that significantly extends the service life of steel pipes-from 5-10 years to as long as 50-100 years. This coating consists of:
First Layer: Fusion Bonded Epoxy (FBE) > 100μm
Second Layer: Adhesive (AD) 170-250μm
Third Layer: Polyethylene (PE) coating 2.5-3.7mm
The 3PE coating offers high mechanical strength, outstanding electrical insulation, process precision, and environmental safety.
This advanced anti-corrosion technique is widely adopted globally, particularly in the oil, gas, and water industries. It ensures effective protection of buried pipelines by preventing chemical corrosion and physical damage.
Typical usage includes:
Oil and gas transmission pipelines
Urban water and gas distribution networks
Industrial fluid transport systems
