The polyethylene coating method, which is also called 3-layer coating, is the most preferred external coating application. It shows high resistance against impacts and corrosion. Three Layer Polyethylene (3LPE) is a multilayer coating composed of three functional components: A high performance Fusion Bonded Epoxy (FBE) primer, followed by a copolymer adhesive and an outer layer of polyethylene which provides tough, durable protection. 3LPE systems provide excellent pipeline protection for small and large diameter pipelines operating at up to moderately high temperatures. PE coating is generally used at the potable water pipeline, petrolium and gas pipelines . PE coating provides an excellent protection due to its properties such as resistance to aging and impact.
