A number in parentheses indicates the year of last reapproval. A superscript epsilon ( e ) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. 1. Scope 1.1 This specification 2 covers two grades of electric- resistance-welded steel pipe in NPS 2 to NPS 30 inclusive, with nominal (average) wall thickness up to 0.500 in. (12.70 mm), inclusive, and in nominal sizes NPS 3 / 4 to NPS 5 inclusive with nominal (average) wall thickness 0.083 in. (2.11 mm) to 0.134 in. (3.40 mm), depending on size. Pipe having other dimensions (Note 1) may be furnished provided such pipe complies with all other requirements of this specification. The pipe is intended for conveying gas, vapor, water or other liquid; only Grade A is adapted for flanging and bending (Note 2). The suitability of pipe for various purposes is somewhat dependent upon its dimensions, properties, and conditions of service, so that the purpose for which the pipe is intended should be stated in the order. The pipe may be furnished either nonexpanded or cold expanded at the option of the manufac- turer. When pipe is cold expanded, the amount of expansion shall not exceed 1.5 % of the outside diameter pipe size. N OTE 1—A comprehensive listing of standardized pipe dimensions is contained in ANSI / ASME B 36.10M. N OTE 2—This provision is not intended to prohibit the cold bending of Grade B pipe. 1.2 The values stated in inch-pound units are to be regarded as the standard. The SI values, given in parentheses, are for information only. 2.
