Three Layer Polyethylene Coating
Three Layer Polyethylene Systems (3LPE), a multilayer coating composed of three functional components: a high performance fusion bonded epoxy (FBE), 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 with moderately high operating temperatures.

Features & Benefits
Long Term Corrosion Protection
The FBE component provides excellent adhesion to steel, providing superior long term corrosion resistance and protection of pipelines operating at moderate temperatures .If required, Low Application Temperature(LAT) FBE can be selected as the primer to ensure low preheating conditions and long term integrity of high strength steels(X80 or higher)
In addition, 3LPE systems offer an excellent resistance to cathodic disbondment, reducing lifecycle cost of cathodic protection.
Bredero Shaw Advanced Manufacturing Systems allow for a customized 3LPE System to your specific project.
Can be applied to pipe diameters from 51 mm (2”) to over 1220 mm (48”).
Can be applied in a wide range of thicknesses to cost effectively meet unique project specifications and performance requirements.
Good Mechanical Protection
The tough outer PE layer protects pipelines during transportation and installation thereby reducing costly repairs while also providing added in-ground protection against shear forces, chemicals and abrasive soil conditions.
By increasing the thickness of the PE outer layer, the 3LPE System can provide a high level of mechanical protection across a variety of difficulty environments without requiring the use of costly backfill.
