What kind of water pipe material is needed for chilled water circulation pipelines

     For chilled water circulation pipelines, materials suitable for low-temperature applications need to be selected to ensure that the pipelines can maintain durability and stable performance during the chilled water circulation process. The following are some materials commonly used for chilled water circulation pipelines:

     Stainless Steel: Stainless steel is a common choice, especially when high corrosion resistance and biocompatibility are required. 316 stainless steel is usually used for chilled water pipelines because it has good corrosion resistance at low temperatures. Stainless steel pipelines can also withstand thermal contraction and expansion under low-temperature conditions and have high cold resistance.

     Copper: Copper is a material with good thermal conductivity and is suitable for chilled water circulation systems because it helps distribute temperature evenly in the pipeline. Copper pipes have good tolerance for low-temperature environments, but at very low temperatures, material selection may need to be considered to prevent coolant temperature from causing damage to the pipeline.

     Polyethylene (PE): Polyethylene is a plastic material and is usually used as the insulation layer for chilled water pipelines. Although it is not the main pipeline material, it can be used for external insulation to reduce temperature loss of the coolant and improve system efficiency.

    CPVC (Chlorinated Polyvinyl Chloride): CPVC is a plastic material with good low-temperature resistance and is suitable for some low-temperature chilled water applications. It has corrosion resistance and mechanical strength, but it is necessary to ensure that the selected CPVC pipe meets the requirements for low-temperature applications.

     PVC (Polyvinyl Chloride): PVC pipes are usually used in some low-temperature cooling water or chilled water systems. However, it should be noted that PVC may not be sufficiently resistant to extreme low temperatures, so it should be selected according to specific applications.

     Using stainless steel pipes with external plastic-coated insulation layers can have some advantages, especially in specific applications of chilled water circulation pipelines:

     Improved insulation performance: The external plastic-coated insulation layer can effectively reduce the temperature loss of cooling water or chilled water in the pipeline and improve the thermal efficiency of the system. This is very important for applications that need to maintain stable water temperature, such as industrial cooling and air conditioning systems.

     Prevent condensation and water vapor formation: The external insulation layer can reduce the temperature difference on the pipeline surface, thereby reducing the risk of condensation and water vapor formation. This is important for maintaining a dry state of the pipeline and the surrounding environment, because water vapor can lead to corrosion and maintenance problems.

     Reduce the amount of pipeline coolant: Due to the more stable temperature inside the pipeline, the external insulation layer can reduce the usage of coolant, thereby saving energy costs.

     Improve the durability of the pipeline: The external insulation layer can prevent the pipeline from being affected by freezing and thermal expansion in low-temperature environments, thereby prolonging the service life of the pipeline.

     Reduce environmental impact: By reducing heat loss, the external insulation layer can reduce energy consumption and help reduce carbon emissions and environmental impacts.
