The most common material for power plant piping is:

Steel is the most common material for power plant piping due to its strength, durability, and resistance to high temperatures and pressures, which are typical conditions in power generation facilities. Steel can handle the demanding environments within a power plant, making it ideal for transporting steam, water, and other fluids. Its structural integrity ensures long-lasting performance and reduces the risk of leaks or failures in the system.

Additionally, steel can be easily welded and fabricated, allowing for versatile design and installation options tailored to the specific needs of the power plant. The material is also cost-effective compared to other options, striking a balance between performance and budget considerations.

While plastic and ABS pipes are used in some applications, they do not possess the same level of strength or temperature resistance required in high-pressure systems. Alloyed nonferrous materials, while lightweight and resistant to corrosion, are typically more expensive and may not provide the required strength for heavy-duty power plant operation. Forged cast materials are mostly used for specific components like fittings or valves but are not commonly employed as the primary piping material. Therefore, steel remains the prevalent choice for power plant piping.
