1. Excellent thermal insulation performance: polyurethane insulation material has a low thermal conductivity, which can effectively reduce energy loss and improve the pipe insulation effect.
2. good corrosion resistance: polyurethane insulation material has good acid and alkali resistance, which can effectively prevent the pipe from being corroded and extend the service life of the pipe.
3. convenient and quick construction: polyurethane buried insulation pipe is prefabricated in the factory and easy to install on site, which can improve the construction efficiency and reduce the construction time.
4. beautiful appearance of the pipe: polyurethane buried insulation pipe has a smooth surface, beautiful appearance, can improve the overall aesthetics of the pipeline.
5. Good seismic performance: polyurethane insulation material has good flexibility and elasticity, can effectively resist the role of external forces such as earthquakes, to ensure the safety of the pipeline.
However, polyurethane buried insulation pipe also has some disadvantages:
1. high cost: compared with other insulation materials, polyurethane insulation material price is higher, increasing the project investment cost.
2. limited waterproof performance: the waterproof performance of polyurethane insulation material is relatively poor, need to strengthen the waterproof measures in the construction process to prevent water infiltration into the pipe.
3. Higher installation requirements: polyurethane buried thermal insulation pipe installation requirements are high, need professional construction team for construction, otherwise it is easy to appear quality problems.
In summary, polyurethane buried thermal insulation pipe has good thermal insulation performance and corrosion resistance, but the cost is higher and the construction requirements are higher. When choosing to use polyurethane buried insulation pipe, you need to consider the engineering requirements, economic and construction conditions and other factors.
