The external 3PE anti-corrosion adopts a three-layer structure: the bottom layer is epoxy powder anti-corrosion, the middle layer is adhesive to enhance adhesion, and the outer layer is polyethylene mechanical protection. The interior is coated with epoxy paint to prevent corrosion by oil, gas and water.

Its advantages lie in the efficient and durable internal and external coordination, which extends the service life of steel pipes and is widely used in pipeline fields such as oil, natural gas, water supply and drainage.
