Description:
ASTM A210 is the standard covers seamless medium-carbon steel
boiler and superheater tubes.ASTM A210 also covers
minimum-wall-thickness, tubing sizes, 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.
