1.1 This specification2 covers minimum-wall-thickness, electric-resistance-welded tubes made of carbon steel and carbon-manganese steel intended for use as boiler tubes, boiler flues, superheater flues, and safe ends. 1.2 The tubing sizes and thicknesses
usually furnished to this specification are
1/2 to 5 in. [12.7 to 127 mm] in outside
diameter and 0.035 to 0.360 in. [0.9 to 9.1 mm], inclusive, in
minimum wall thickness. Tubing having other dimensions may be
furnished, provided such tubes comply with all other requirements
of this specification.
1.3 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 Optional supplementary requirements are provided and when desired, shall be so stated in the order. 1.5 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. |
