ASTM A210 A1 seamless boiler tubes are mainly used to manufacture headers, main steam pipes, etc. for the heating surface of high-pressure boilers, and are power station boilers and superheaters.

Alloy steel seamless pipes covered by ASTM A213, ASTM A335, and ASTM A519 are used in various high-temperature and high-pressure applications.

STPG370 is a low-carbon steel pipe material commonly used in some low-pressure pipeline systems.
