Description:
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.
