What type of pipe is typically used for high-pressure steam systems?

In high-pressure steam systems, the typical choice for piping is Schedule 80. This is due to its thicker walls compared to Schedule 40 and Schedule 10 pipes, which provides enhanced strength and durability under higher pressures. Schedule 80 pipes are specifically designed to withstand greater stress, which is critical in high-pressure applications where the potential for leaks or bursts can pose significant safety and operational risks.

The thicker wall of Schedule 80 pipes not only contributes to their ability to manage higher pressure but also helps in maintaining the integrity of the system over time. They are commonly used in industrial settings where steam generation and distribution require reliable and robust infrastructure. Additionally, while Schedule 160 has even thicker walls, it is not as commonly used for steam systems as Schedule 80, which strikes a good balance between strength, weight, and cost for this type of application.
