ASTM A178 /ASME SA178 ELETRIC RESISTANCE WELDED CARBON STEEL BOILER TUBES
This standard is issued under the fixed designation A 178/A 178M; the number immediately following the designation indicates the year of original adoption or, in the case of
revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (2) indicates an editorial change since the last revision or
reapproval.
This specification has been approved for use by agencies of the Department of Defense. Consult the DoD Index of Specifications and Standards for specific year of issue which has
been adopted by the Department of Defense.
1.Scope
1.1 This specification 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.
NOTE 1 Α Type C and D tubes are not suitable for safe-ending for forge welding.
1.2 The tubing sizes and thickness usually furnished to this specification are 1/2 to 5 in. [12.7 to 127 mm] in outside diameter and 0.035 to 0.320 in. [0.9 to 8.1 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 When these products are to be used in applications conforming to ISO Recommendations for Boiler Construction the requirements of this Specification A 520 shall supplement
and supersede the requirements of this specification.
1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. W within the text, the SI units are shown in brackets. The values stated in
each system are not exact equivalents; therefore, each system must b 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 specified in the order.
