What material is typically used for chilled water piping systems?

Chilled water piping systems commonly utilize copper due to its excellent thermal conductivity, corrosion resistance, and ease of installation. Copper is a reliable choice for transferring chilled water efficiently without significant energy loss, making it ideal for HVAC applications. Moreover, copper pipes are less likely to develop pinhole leaks, which is crucial for maintaining system integrity in a chilled water application.

While other materials can be used for piping, copper stands out because of its proven performance in cooling systems. Plastic may lack the durability and structural integrity needed for high-pressure applications, stainless steel is often more expensive and typically used in specific applications where corrosion resistance is paramount, and iron, while strong, can be susceptible to corrosion if not properly maintained. Thus, the distinctive benefits of copper make it the preferred choice for chilled water piping systems.
