The three-layer PE anti-corrosion structure includes fusion bonded epoxy-powder bottom layer, polymer adhesive middle layer and polyethylene top layer. The epoxy powder is a kind of thermo setting nontoxic coating, forming the high molecular weight cross linking structure coating after solidifying ,featuring good chemical anti-corrosion and higher mechanical properties.The function of epoxy-powder bottom layer is to form continuous coating ,providing excellent adhesive by agglutinating and solidifying the steel tube surface with good chemical resistance and cathodic disbanding resistance .The function of polymer adhesive is to agglutinate the epoxy powder before gelation,and to agglutinate the polyethylene top layer ,which unites all three layer together .The three layer PE process ,with the epoxy powder coating as bottom layer, binding and bundling through polyethylene,PE and adhesive ,is widely used in steel pipes anti-corrosion at home and abroad ,and applied to the oil pipeline and gas pipeline ,as well as to the gas supply and water supply for civil use.

Huashida PERT rigid insulation pipe is also one of the products of insulation pipe equipment , what are the advantages of the equipment.

The 3PE (three-layer polyethylene) coating system is widely used in the oil and gas industry to protect pipes from corrosion. The process involves applying multiple layers of coatings to pipes, enhancing durability and longevity. To ensure the highest quality of these coatings, advanced 3LPE pipe equipment is essential.
