Steel pipe 3-layer PE coating line meets the requirements of applying three-layer PE anti-corrosion coating on steel pipes with a diameter of 89-3000mm, and produce 3LPE coated pipes that meet international standards.
About Pipeline 3LPE Anti-corrosion Technology
3-Layer Polyethylene (3LPE) is a multi-layer corrosion resistant external coating composed of three functional components:
◆ A high performance Fusion Bonded Epoxy (FBE) primer（FBE>100um）, followed by a copolymer adhesive （AD 170～250um) and an outer layer of polyethylene （PE 2.5～3.7mm) which provides tough, durable protection.
◆ 3LPE anti-corrosion technology combines the excellent properties of epoxy coating and extruded polyethylene anti-corrosion coating, and combines the interface properties and chemical resistance properties of epoxy coating with the mechanical protection properties of extruded polyethylene, significantly extends the service life of pipelines underground or underwater.
◆ The 3 layer polyethylene coated pipes are widely used for oil&gas transmission around the world and for transportation of drinking water and other fluids.
◆ Preheat bare pipe
