| Key Benefits | Description |
|---|---|
| Lightweight Design | Lightweight structure for easy transportation, installation, and handling, while reducing labor costs. |
| Excellent Flexibility | Fewer pipe joints and outstanding flexibility improve installation efficiency and system reliability. |
| Superior Thermal Insulation | Polyurethane foam insulation with thermal conductivity as low as 0.013 W/(m·K), providing 4–9 times better insulation performance than conventional materials. |
| Long Service Life | A closed-cell rate of up to 92% ensures excellent insulation performance and a service life of more than 50 years. |
| Outstanding Corrosion Resistance | The tightly bonded PU foam layer effectively isolates moisture and air, protecting the pipeline from corrosion even in harsh environments. |
| Cost Efficiency | Reduces excavation costs by up to 50%, lowers civil construction costs by up to 90%, and shortens project installation time significantly. |
| Energy Saving | Excellent thermal performance minimizes heat loss and helps reduce long-term operating costs. |
| Eco-Friendly Solution | Requires less installation space, generates minimal production waste, and supports sustainable, environmentally friendly construction. |
