Seamless Steel Pipe OD88.9mm Sch40 Hastelloy C276 Pipe corrosion resistance
ASTM A 249 / SA 249
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.
