Tycoon piping is one of the large suppliers for high quality 3LPE pipes. 3 layer polyethylene coating(3LPE) is a multilayer coating composed of three functional components such as: Grafted copolymer adhesive, FBE primer and an outer layer of polyethylene to provide great corrosion protection and mechanical protection for gas & oil pipelines at operating temperatures upto 80 degree celsius. The 3LPE System achieves superior long term corrosion resistance and excellent mechanical protection for large and small diameter pipelines operating at high temperature thanks to strong adhesion of FBE to steel and the tough of outer layer with high density polyethylene. The 3LPE system can be applied in a great range of thicknesses to meet project requirements and specifications.
The three coating layers in 3-LPE coated pipe are as follows:
Layer 1: It is called corrosion protective layer. This layer is fusion of bonded epoxy which offers very good corrosion protection. The fusion bonded epoxy has a excellent bonding with the blasted steel surface.
Layer 2: It is called copolymer adhesive layer. The copolymer adhesive is basically a maleic anhydride grafted polyethylene compound. The material has excellent chemical bonding to the fusion bonded epoxy and the top layer polyethylene.
Layer 3: This layer is for physical protection and it also consists of polyethylene. Since the polyethylene and copolymer adhesiveare are similar, they bond well with each other.
