What is the maximum average amount of hydrogen sulfide allowed in gas for the installation of copper and brass piping?

• A. 0.1 grains per 100 standard cubic feet
• B. 0.3 grains per 100 standard cubic feet
• C. 0.5 grains per 100 standard cubic feet
• D. 1.0 grains per 100 standard cubic feet

Answer: (B)

The maximum average amount of hydrogen sulfide permitted in gas for copper and brass piping is 0.3 grains per 100 standard cubic feet. This threshold is critical because hydrogen sulfide can cause significant corrosion in these metals, leading to damage in piping systems and potential failures. Setting this limit at 0.3 grains per 100 standard cubic feet helps to ensure that the integrity of gas piping systems made from copper and brass is maintained. If the concentration exceeds this level, the risk of corrosion and the subsequent operational issues increase significantly, which can compromise safety and efficiency in gas distribution systems. Therefore, adherence to this standard is essential for both the longevity of the equipment and the safety of those who interact with these systems.
