- Any system requiring heat transfer under high-temperature and high-pressure conditions
ASTM A213 Related Standard
ASTM A213 is often used in conjunction with the following standard:
ASME SA213
→ The American Society of Mechanical Engineers (ASME) adopts ASTM standards in its boiler and pressure vessel codes.
Therefore, in practical applications, you will often see the standard referred to as:
ASTM A213 / ASME SA213
ASTM A213 vs ASTM A312
- Choose ASTM A213: when high-temperature performance is required for heat exchanger tubes or boiler tubes
- Choose ASTM A312: when stainless steel piping is needed for fluid or gas transportation
