According to regulations, what type of standards must copper and brass piping in a natural gas piping system comply with?

Copper and brass piping used in natural gas systems must comply with the standards set forth by ASTM (American Society for Testing and Materials), specifically ASTM B 88 and ASTM B 280. ASTM B 88 covers the specification for seamless copper water tubes, which ensures that the piping can withstand appropriate pressures and operating conditions typically found in gas applications. ASTM B 280, on the other hand, pertains to the specifications for copper and copper-alloy pressure fittings.

Meeting these standards is vital for safety and reliability, as natural gas systems must be constructed from materials that can handle the specific requirements of gas transport, including pressure, temperature, and corrosion resistance. Therefore, adherence to ASTM standards ensures that the piping is tested and certified for operational use in a natural gas environment, thereby minimizing the risk of leaks or failures.
