　　3peProduction process and performance characteristics of anti-corrosion steel pipe products

　　The base materials for 3pe anti-corrosion steel pipes include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the petroleum pipeline industry due to its excellent corrosion resistance, water vapor permeability resistance, and mechanical properties. The anti-corrosion coating of 3PE anti-corrosion steel pipes is crucial for the service life of buried pipelines. For pipelines of the same material, some may not corrode after being buried underground for decades, while others may leak within a few years. It's because they use different external anti-corrosion coatings.
