What is 3LPE coated pipe?

3LPE Coated Pipes consist of 3 layers for pipeline coating.

Layer 1 consists of Fusion Bonded Epoxy. This later protects against corrosion and is fusion bonded with the blasted steel surface.

Layer 2 is a copolymer adhesive that has excellent chemical bonding to the inner layer and the top layer of polyethylene.

Layer 3 is the layer of polyethylene used for protection against any physical damage to the pipes.

Thickness of 3LPE Coating on Steel Pipes

minimum 125 um Epoxy layer thickness
minimum 150 um copolymer layer thickness
minimum thickness of 1.8 mm to 4.7 mm polyethylene or polypropylene layer

Moreover, 3PE can strengthen the pipeline’s mechanical properties, high electrical resistance, waterproof, and wearable, anti-aging. It could protect pipe from the heat loss which only account for 1/4 of pipe. 3PE coating pipe integrated with the advantages of FBE and the PE. This is getting more and more widely used in buried pip
