ASTM A135 Standard for Electric Resistance Welded Steel Pipe

The specification ASTM A135 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 3/4 to 5 in. (19 to 127 mm) inclusive with nominal (average) wall thickness 0.083 in. (2.11 mm) to 0.314 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 in intended for conveying liquid, gas, or vapor; and only Grade A is adapted for flanging and bending. The suitability of pipe for various purposes in 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. T he pipe may be furnished either nonexpanded or cold expanded, the amount of expansion shall not exceed 1.5％ of the outside diameter pipe size.

A comprehensive listing of standardized pipe dimensions is contained in ANSI B36.10. This provision is not intended to prohibit the cold bending of Grade B pipe.

The values stated in inch-pound units are to be regarded as the standard.
