What standard specification must steel tubing comply with for gas lines?

Steel tubing used for gas lines must comply with ASTM A 539. This specification covers electric-resistance-welded steel pipes intended for use in gas, oil, and water pipelines and is crucial for ensuring the integrity and safety of gas distribution systems. The materials and manufacturing processes outlined in ASTM A 539 specify the chemical and mechanical properties required to ensure the tubing can withstand high pressures and corrosive environments often associated with gas lines.

Standards like ASTM A 106 apply to seamless carbon steel pipes for high-temperature service, which are not specifically designed for gas transmission, while ASTM A 512 and ASTM A 254 relate to different forms of steel products not applicable to gas line construction. Selecting materials that meet the ASTM A 539 requirements helps to ensure the overall reliability and safety of gas systems, preventing potential leaks and failures in the infrastructure.
