ASTM A210(ASME SA210/210M) ?
Seamless carbon steel pipe for high pressure boiler and superhearter
Size range from OD: 12.7 – 127mm (1/2 – 5 in.)??? WT: 0.9 – 12.7mm (0.035 – 0.5in.), or as per customer’s requirement
ASTM A210 is the standard covers seamless middle-carbon steel boiler and superheater tubes. It is minimum-wall-thickness tubes under this standard. Mainly used in boiler & boiler flues including safe ends, arch and stay tubes. ASTM A210 provides tensile and hardness properties but only applicable to certain size limitations. Material manufacturing shall be killed. Tubes shall be made by seamless process, marked as either hot-finished or cold-finished. Surface condition shall be specifically stated in the order. Chemical composition shall conform to the requirements. Elemental composition other than listed here shall not be permitted. Tension test, flattening test, flaring test, hardness test, hydrostatic or nondestructive electric test shall be made on specimens. Superheater tubes shall be formed without defects and shall withstand expansion, beading, forging, welding, and bending.
