Forged steel is commonly used in power plants for applications that require high strength and the ability to withstand high pressures and temperatures. In the context of this question, welded pipe fittings are typically made from forged steel, as this material provides the strength necessary for the various stresses encountered in piping systems.

Welded pipe fittings play a crucial role in connecting pipelines and directing the flow of fluids in a power plant infrastructure. The forging process enhances the mechanical properties of steel, making it less likely to fail under extreme operating conditions, which is essential in preventing leaks or catastrophic failures in the system.

The other choices, while they may utilize various forms of steel and materials, do not exemplify as typical an application for forged steel. For instance, heat exchangers may use other materials better suited for thermal conductivity rather than structural integrity, while pressure vessels generally require materials that can handle specific design criteria, which could include but are not limited to forged steel. Combustion chambers are often built with materials that can withstand high heat and corrosive environments, where other materials may be more appropriate than forged steel.

Thus, the application of welded pipe fittings stands out as a primary use of forged steel in the context of power plants due to the materials’ superior strength and reliability
