What type of piping is primarily used in high-temperature applications?

Alloy steel piping is particularly suited for high-temperature applications due to its ability to withstand elevated temperatures and pressures. This type of piping is designed with specific chemical compositions and heat treatment processes that enhance its mechanical properties, making it resistant to thermal expansion and deformation under stress. In environments where high temperatures are common, such as power plants and refineries, alloy steel provides the necessary strength and durability.

While stainless steel piping is also used in high-temperature situations and offers excellent corrosion resistance, alloy steel is often preferred for more extreme conditions because of its superior strength at high temperatures. Plastic piping, on the other hand, is typically not used in high-temperature applications due to its susceptibility to deformation and degradation when exposed to heat. Copper piping can handle some elevated temperatures, but it is less common in high-temperature industrial applications than alloy steel due to cost and strength limitations.
