1. 3PE anti-corrosion steel pipe has high sealing performance. Long-term operations can greatly save energy, reduce costs, and protect the environment.

2. It has strong corrosion resistance, a simple and fast structure, and a service life of 30-50 years.

3. At low temperatures, PE has good corrosion resistance impact resistance, and low water absorption.

4. It has high epoxy strength, low polyethylene water absorption, and good hot melt adhesive softness. Has high anti-corrosion 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 the primary technical system for external anti-corrosion of buried pipelines at home and abroad. It has good anti-corrosion performance, low water absorption, and high mechanical strength. In recent years, it has been increasingly widely used in domestic buried water, gas, and oil pipelines.
