3PE anti-corrosion steel pipe base materials include seamless steel pipe, spiral steel pipe, and straight seam steel pipe. The three-layer polyethylene (3PE) anti-corrosion coating is widely used in the oil pipeline industry due to its excellent corrosion resistance, water vapor penetration resistance, and mechanical properties. The anti-corrosion layer of 3PE anti-corrosion steel pipe is crucial to the lifespan of buried pipelines. Pipes of the same material can remain uncorroded underground for decades, while others leak within years. This is because they use different external anti-corrosion layers.

3PE anti-corrosion steel pipe refers to a three-layer polyethylene coating external anti-corrosion steel pipe, a commonly used type of anti-corrosion pipeline in China. Other anti-corrosion methods include IPN8710, FBE epoxy powder, and epoxy coal tar pitch. Generally, it refers to the external wall anti-corrosion of the steel pipe.

Many people only know a little about the uses of 3PE anti-corrosion steel pipe, but its applications are truly wide-ranging. It is suitable for underground water supply and drainage in coal mines, underground spraying, positive and negative pressure ventilation, gas extraction, fire sprinkler systems, and other pipeline networks. Pipelines for transporting process water, waste residue, and return water in thermal power plants. Highly applicable to water supply pipelines for sprinkler and spray systems. Cable protection conduits for power, telecommunications, and highways. Suitable for water supply in high-rise buildings, heating networks, tap water projects, gas transmission, and buried water pipelines. Process pipelines for transporting corrosive media in industries such as oil transportation, chemical and pharmaceutical manufacturing, and printing and dyeing. Wastewater treatment discharge pipes, sewage pipes, and anti-corrosion engineering for biological treatment ponds. Agricultural irrigation pipes, deep well pipes, drainage pipes, and other applications. It can be said that 3PE anti-corrosion steel pipes are indispensable in current construction, and it is believed that with the advancement of technology, they will achieve even greater success in the future.
