1. 3PE anti-corrosion steel pipes have excellent sealing performance, which can significantly save energy, reduce costs, and protect the environment during long-term operation.
2. 3PE anti-corrosion steel pipes have strong corrosion resistance, a simple and rapid structure, and a service life of 30-50 years.
3. At low temperatures, PE exhibits good corrosion resistance and impact resistance, with low water absorption.
4. 3PE anti-corrosion steel pipes simultaneously possess high epoxy strength, low polyethylene water absorption, and good hot melt adhesive flexibility, resulting in high corrosion resistance reliability. This anti-corrosion method is characterized by a simple production process, good anti-corrosion effect, and low price.
Three-layer polyethylene anti-corrosion is one of the primary technical systems for external anti-corrosion of buried steel pipelines, both domestically and internationally. It features excellent anti-corrosion performance, low water absorption, and high mechanical strength, and has been increasingly widely used in buried water, gas, and oil pipelines in China in recent years.
