Which piping material is typically used for high-temperature applications?

Stainless steel is the preferred choice for high-temperature applications due to its excellent resistance to oxidation and corrosion at elevated temperatures. It maintains its structural integrity and mechanical properties in conditions that would typically degrade other materials. This capability makes stainless steel a reliable choice for piping systems that operate at high temperatures, as it can withstand thermal expansion and pressure without compromising performance.

In contrast, while aluminum and copper have beneficial thermal conductivity, they are not suitable for high-temperature environments. Aluminum can lose strength and deform under high heat, and copper may have issues with thermal expansion and could oxidize in extreme heat. PVC, on the other hand, has a relatively low melting point and is not designed for high-temperature applications, making it unsuitable for scenarios where heat could compromise its integrity. Thus, stainless steel stands out as the most effective and resilient option in high-temperature piping applications.
