1. Scope | ||
1.1 This specification2 covers minimum-wall-thickness, seamless medium-carbon steel, boiler tubes and boiler flues, including safe ends (see Note 1), arch and stay tubes, and superheater tubes. 1.2 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 this specification.
1.3 Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness. 1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order. |
