I would like to ask: for pipes that need to be kept cool at 20°C in summer and insulated to maintain a temperature of -15°C in winter, what kind of insulation material should be used?

For situations where it is necessary to maintain the temperature of pipelines throughout different seasons, it is very important to choose appropriate insulation materials and design a moisture-proof layer. 1. **Material selection**: Polyurethane foam is an excellent insulating material, as it offers good thermal insulation properties and is suitable for low-temperature environments. It is reasonable to choose polyurethane as a material for insulation and heat retention. 2. **Moisture barrier treatment**: The moisture barrier should generally be placed outside the insulation layer to prevent moisture from entering and affecting the insulation performance. Common moisture-barrier materials include aluminum foil, glass fiber cloth, etc., which can effectively prevent moisture from entering. 3. **Installation location of the heating tape**: The heating tape is usually placed inside the insulation layer or in close contact with the surface of the pipe, rather than on the outer surface of the moisture barrier. This ensures that in low-temperature environments, heat can be transferred directly to the pipes, preventing the liquid inside them from freezing. Summary: - Use polyurethane insulation material. - Install a moisture barrier outside the insulation material. - The heating strip should be installed inside the insulation layer or in close contact with the pipe surface. This design ensures that the pipeline remains within the desired temperature range throughout different seasons. .

Why use a heating/cooling strip for insulation?
