ASTM A210/A210M covers minimum-wall-thickness, seamless medium-carbon steel, boiler tubes and boiler flues, including safe ends, arch and stay tubes, and superheater tubes. The tubing sizes and thicknesses usually furnished to this specification are 1⁄2 in. to 5 in. [12.7 to 127 mm] in outside diameter and 0.035 to 0.500 in. [0.9 to 12.7 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of ASTM A210/A210M.
Manufacture: the tubes shall be made by the seamless process and shall be either hot-finished or cold-finished, as specified.
Heat Treatment: hot-finished tubes need not be heat treated. Cold finished tubes shall be given a subcritical anneal, a full anneal, or a normalizing heat treatment after the final cold finishing process.
Surface Condition: if pickling or shot blasting or both are required, this shall be specifically stated in the order.
Inspection & Test: chemistry composition analysis, tensile test, flattening test, flaring test, hardness test, NDT, surface inspection and dimension check.
Length: 5800mm; 6000mm; 6096mm; 7315mm; 11800mm; and so on.
Max length: 25000mm, also U bending can be offered.
