The 3LPE System achieves superior long-term corrosion resistance and excellent mechanical protection for large and small-diameter pipelines operating at high temperatures. The 3LPE system can be applied in a great range of thicknesses to meet project requirements and specifications. It is highly abrasion resistant and is generally used where the chances of damage are high such as in the Rocky Mountains or for drilling operations.

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 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 epoxy and the top layer of 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.
