Abstract:

This specification covers two grades of electric-resistance-welded steel pipe intended for conveying gas, vapor, water or other liquid. The steel shall be made by either or both basic-oxygen or electric-furnace processes. Steel may be cast in ingots or may be strand cast. The pipe shall be manufactured from flat rolled steel in individual lengths or continuous length by electric-resistance or electric-induction welding without the addition of extraneous material. The weld seam of electric-resistance welded pipe to Grade B pipe shall be heat treated after welding or processed in such a manner that no untempered martensite remains. Tensile and chemical requirements of the steel are provided. Specimens of the steel pipes are subject to flattening test and hydrostatic test. A nondestructive electric test, either electromagnetic (eddy current) or ultrasonic test, may be preferred as an alternate to the hydrostatic test.

Scope:

1.1 This specification covers two grades of electric-resistance-welded steel pipe in NPS 2 to NPS 30 [DN 50 to DN 750] 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 [DN 20 to DN 125] 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 0) 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 0). 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 manufacturer. When pipe is cold expanded, the amount of expansion shall not exceed 1.5 % of the outside diameter pipe size. Note 0A comprehensive listing of standardized pipe dimensions is contained in ASME B36.10M.

Note 0

This provision is not intended to prohibit the cold bending of Grade B pipe.

1.2 The values stated in either SI or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system is to be used independently of the other.
