Standard Specification for Seamless Carbon-Molybdenum Alloy-Steel Boiler and Superheater Tubes
1.2This specification covers tubes 1/2to 5 in. [12.7 to 127 mm] inclusive, in outside diameter and 0.035 to 0.500 in. [0.9 to 12.7 mm], inclusive, in minimum wall thickness.
1.3An optional supplementary requirement is provided and, when desired, shall be so stated in the order.
1.4The 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.
