Seamless carbon steel pipe for high pressure boiler and
ASME SA210 is minimum-wall-thickness tubes, the standard covers seamless middle-carbon steel boiler and
superheater tubes. Mainly used in boiler & boiler flues
including safe ends, arch and stay tubes. ASME SA210 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.
