Performance characteristics: The outer wall of the steel pipe is protected by a three-layer polyethylene (3PE) anti-corrosion coating, which has good corrosion resistance, water vapor penetration resistance, and mechanical properties. It has good impact resistance and flexibility, and a service life of up to 30 years.
Application scenarios: It is an advanced pipeline anti-corrosion technology internationally, widely used in pipeline transportation systems in industries such as petroleum, natural gas, chemical, power, and sewage treatment.
product structure
1. Bottom layer: composed of epoxy resin or solvent-free epoxy powder coating, directly coated on the surface of steel pipes, providing good adhesion and chemical corrosion resistance.
2. Intermediate layer: It is a copolymer adhesive that tightly binds the bottom layer of epoxy powder with the outer layer of polyethylene, while providing additional waterproof performance.
3. Outer layer: High density polyethylene material, with excellent mechanical strength, abrasion resistance and anti-aging performance, can effectively resist the corrosion of external environment on the pipeline.
