Reliable 3lpe Steel Pipe Anti-Corrosion Coating for Industrial Applications

Product Description

Reliable 3lpe Steel Pipe Anti-Corrosion Coating for Industrial Applications

The three-layer polyethylene anti-corrosion coating combines the excellent properties of epoxy coating and extruded polyethylene layer: the interface characteristics and chemical resistance of the epoxy coating and the mechanical protection characteristics of extruded polyethylene layer. Therefore, it is very superior as the outer protective layer of buried pipelines. After rigorous scientific testing, the three-layer PE coating can make the life of the buried pipeline reach 50 years. At present, it is recognized as an efficient external pipeline anti-corrosion technology in the world.

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