1.1This specification2 covers several grades, designated T1, T1a, T1b, T2, T11, T12 and T22, of minimum-wall-thickness, electric-resistance-welded, carbon-molybdenum and chromium-molybdenum alloy-steel, boiler and superheater tubes.
1.2The tubing sizes and thicknesses usually furnished to this specification are 1/2to 5 in. [12.7 to 127 mm] in outside diameter and 0.035 to 0.320 in. [0.9 to 8.1 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
1.3Mechanical property requirements do not apply to tubing smaller than 1/8in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.
1.4An optional supplementary requirement is provided for non-destructive examination for certain ASME applications.
1.5The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.5.1Within the text, the SI units are shown in brackets.
1.5.2The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.
