The pipes use 3PE anti-corrosion treatment. What is 3PE?

3PE is an anti-corrosion coating with a three-layer polyethylene structure, comprising a base layer of fused epoxy (FBE), an intermediate adhesive layer, and an outer layer of high-density polyethylene. This anti-corrosion coating is primarily used for the protection of pipes against corrosion, and it effectively prevents damage to the pipes caused by groundwater, chemicals in the soil, and other corrosive factors. .

3PE anti-corrosion refers to an external anti-corrosion technique used for pipes, and it consists of three main components: epoxy powder (FBE), which serves as the underlying anti-corrosion layer and typically has a thickness of more than 100 micrometers. Adhesive: Also known as the intermediate anti-corrosion layer, its thickness is usually between 170 and 250 micrometers. Polyethylene (PE): Used as the outer protective layer, with a thickness range of 1.8 to 3.7 millimeters. The purpose of this technology is to provide a comprehensive protective measure to effectively resist the effects of soil, moisture, chemical agents, electrochemical corrosion, and other adverse environmental factors on pipelines. 3PE anticorrosive steel pipes are widely used in various pipeline systems, such as water supply in coal mines, transportation of process water and waste in thermal power plants, protection of power and communication cables, water supply and hot water supply in high-rise buildings, gas transmission in water supply projects, as well as buried water and water treatment applications.
