Standard Specification for Welded Austenitic Steel Boiler,
Superheater, Heat-Exchanger, and Condenser Tubes
1.1 This specification covers nominal-wall-thickness welded tubes made
from the austenitic steels listed in Table 1, with various grades
intended for such use as boiler, superheater, heat exchanger, or
condenser tubes.
1.2 Grades TP304H, TP309H, TP309HCb, TP310H, TO310HCb, TP316H, TP321H,
TP347H, and TP348H are modifications of Grades TP304, TP309S,
TP309Cb, TP310S, TP310Cb, TP316, TP321, TP347, and TP348, and are
intended for high-temperature service such as for superheaters and
reheaters.
1.3 The tubing sizes and thicknesses usually furnished to this
specification are 1/8 in. [3.2 mm] in inside diameter to 5 in. [127
mm] in outside diameter and 0.015 to 0.320 in. [0.4 to 8.1 mm],
inclusive, in wall thickness. Tubing having other dimensions may be
furnished, provided such tubes comply with all other requirements
of this specification.
1.4 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.
1.5 Optional supplementary requirements are provided and, when one or
more of these are desired, each shall be so stated in the order.
1.6 The values stated in either inch-pound units or SI units are to be
regarded separately as standard. (A combination of 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.
