Product Description

3 Layer Polyethylene (3LPE) Anti-Corrosion Steel Pipe 

3LPE anti-corrosion steel pipe features a three-layer coating system for superior pipeline protection:

  • First Layer: Epoxy powder, ensuring strong adhesion and excellent corrosion resistance.

  • Second Layer: Copolymer adhesive with branched functional groups, bonding the epoxy and polyethylene layers.

  • Third Layer: High-density polyethylene (HDPE), providing mechanical protection and environmental durability.
