Which ASTM standard must plastic piping conform to?

Plastic piping used in LP gas applications must conform to ASTM D 2513. This standard specifically outlines the requirements for materials, design, and construction of plastic piping systems intended for the transport of gas, specifically including gases like propane. The ASTM D 2513 standard focuses on ensuring that the plastic materials used are suitable for their environment, can withstand the pressure they will encounter, and meet safety requirements.

This standard is critical for ensuring the integrity and safety of the piping systems, reducing risks associated with gas leaks, and ensuring that the piping can tolerate various environmental conditions. Adhering to ASTM D 2513 also promotes consistency in manufacturing practices, quality control, and long-term performance of LP gas systems.

The other standards mentioned are associated with different materials or applications which do not apply specifically to plastic piping for gas transport. For instance, ASTM A53 pertains to steel pipes and their specifications used in various applications, ASTM B 280 relates to copper tube for refrigeration and air-conditioning, and ASTM B 88 is concerned with copper water tube. None of these standards address the requirements for plastic piping systems utilized in LP gas applications, making ASTM D 2513 the correct choice.
