ASTM A192 / ASME SA192 Standard covers minimum-wall thickness, seamless carbon steel boiler and superheater tubes for high- pressure service. ASTM A192 / ASME SA192 Tubes sizes and thicknesses usually furnished to this specification are 1⁄2 in. to 7 in. [12.7 to 177.8 mm] outside diameter and 0.085 to 1.000 in.
ASTM A192/A192M-17. This standard applies to boiler tubes used in high-pressure boilers (more than 350MPa). It requires that the tubes can withstand operation under high temperature and high pressure conditions and have good pressure resistance and strength.
ASTM A210/A210M-19. This standard applies to boiler tubes for low and medium pressure boilers (not exceeding 500MPa). It requires the tubes to have high pressure resistance and heat resistance and be able to withstand work under high temperature and high pressure conditions.
ASTM A213/A213M-19. This standard applies to seamless and welded boiler tubes used in boilers and heat exchangers in high-temperature environments. It requires the tubes to be able to withstand work under high-temperature and high-pressure conditions, and to have high corrosion resistance and heat resistance.
