Performance characteristics: Specially designed for efficient underground pipeline systems, it has excellent anti-corrosion performance, efficient insulation performance, good mechanical performance, convenient construction, environmental protection and energy saving, and wide applicability, ensuring stable operation in complex environments.
Application scenarios: Widely used for transporting various media such as oil, natural gas, hot water, steam, etc
structural composition
1. Working steel pipe layer: the innermost layer used for transporting oil, natural gas or other substances. Anti corrosion layer: usually composed of epoxy powder coating, etc. The selected anti-corrosion material has good corrosion resistance, aging resistance, strong adhesion and other properties, which can effectively prevent the steel pipe from being corroded by soil, moisture, acid and alkali corrosive media, and extend the service life of the steel pipe.
2. Thermal insulation layer: polyurethane rigid foam plastic, characterized by low thermal conductivity, good thermal insulation effect, high porosity, excellent waterproof performance, etc.
3. Outer protective pipe: usually made of materials such as high-density polyethylene (HDPE).
