What does B16.47 cover in API standards?

• A. Small Diameter Steel Flanges
• B. Standard Flanges
• C. Large Diameter Steel Flanges
• D. Flange Gaskets

Answer: (C)

B16.47 specifically covers large diameter steel flanges that are used in piping systems. This standard provides specifications for dimensions, tolerances, materials, and markings that are essential for the manufacture and use of these flanges. B16.47 is particularly important for applications involving larger pipelines, which demand flanges capable of handling higher pressures and larger volumes of fluid. By detailing the requirements for large diameter flanges, it ensures compatibility and safe interoperability within various systems, particularly in industries related to oil and gas.

Being aware of the correct specifications outlined in this standard is crucial for engineers and professionals involved in the design and installation of piping systems, as it directly impacts the effectiveness and reliability of large installations.
