Product Description

Product Description


3-Layer Polyethylene (3LPE) Anti-Corrosion Steel Pipe Coating Line
The 3LPE anti-corrosion steel pipe is composed of three distinct layers:
First Layer – Epoxy Powder Coating: Applied directly onto the steel surface, providing excellent adhesion and corrosion resistance.
Second Layer – Copolymer Adhesive: A bonding layer with branched functional groups that ensure strong integration between the epoxy and polyethylene layers.
Third Layer – High-Density Polyethylene (HDPE): The outer protective layer that offers high mechanical strength, low water absorption, and long-term durability.
These three layers combine to form a highly effective anti-corrosion system, widely used in pipeline protection around the world.
