What is the pressure and temperature limitation for standard fittings in steam pipes?

The correct answer is based on the commonly accepted industry standards for pressure and temperature limitations of standard fittings used in steam piping applications. Standard fittings, including items such as elbows, tees, and reducers, are often rated to handle specific maximum allowable pressure and temperature conditions to ensure safety and prevent failures in steam systems.

Typically, a rating of 125 PSI and 450 degrees Fahrenheit indicates a good balance between operational capacity and the safety margins required for standard piping systems. This ensures that the fittings can withstand the pressures and temperatures associated with many steam applications without compromising structural integrity.

In this context, recognizing these limitations is crucial for the design and operation of steam systems. Adhering to these ratings helps prevent accidents, equipment failure, and inefficiencies in the system. Properly rated fittings ensure reliability and longevity in steam piping systems, which is a key consideration in engineering and design.

Other options present different pressure and temperature limitations that may not align with the accepted standards for standard fittings in steam systems, emphasizing that the selected answer appropriately reflects common industry practice.
