ABSA 4th Class Practice Exam

A typical application of forged steel in a power plant is indeed related to pipe fittings. Forged steel is known for its superior strength and durability compared to other materials, making it ideal for high-pressure and high-temperature applications commonly found in power plants. Pipe fittings are essential components that connect various pipes, allowing for changes in direction or to connect different sections of piping systems.

In power plants, where safety and reliability are critical, the mechanical properties of forged steel help ensure that pipe fittings can withstand the significant forces and pressures they encounter during operation. Moreover, forged steel's ability to resist thermal fatigue and corrosion further underscores its suitability for applications involving steam and hot liquids.

Although other options like superheated steam lines, ash handling systems, and heat exchangers also use robust materials, the specific role of pipe fittings makes forged steel particularly advantageous for those components due to the demands they face.
