Carbon Steel 3LPE Coated Pipe

Product Details:


Product Description

3 layer polyethylene coating (3LPE) is a multilayer coating composed of three functional components: a FBE primer, a grafted copolymer adhesive and an outer layer of polyethylene to provide excellent corrosion protection and mechanical protection for oil & gas pipelines at operating temperature up to 80oC.
The 3LPE System achieves superior long term corrosion resistance and excellent mechanical protection for small and large diameter pipelines operating at high temperature thanks to strong adhesion of FBE to steel and the tough outer layer of high density polyethylene. The 3LPE system can be applied in a wide range of thicknesses to meet project specifications and requirements.

The three coating layers in 3-LPE coated pipe are as follows:

Layer 1: This is the corrosion protective layer. This layer is of fusion bonded epoxy which offers very good corrosion protection. The fusion bonded epoxy has a very good bonding with the blasted steel surface.

Layer 2: This layer is the copolymer adhesive. The copolymer adhesive is a maleic anhydride grafted polyethylene compound. This material has good chemical bonding to the fusion bonded epoxy and the top layer polyethylene.

Layer 3: This layer is for physical protection and consists of polyethylene. Since the copolymer adhesive and polyethylene are similar, they bond well with each other
