Scope:

This specification covers black and hot-dipped galvanized welded and seamless steel pipe in NPS (Note 1) 1/8 to NPS 16 inclusive with nominal (average) wall thickness as given in Tables 1, 2, 3, and 4. Pipe having other dimensions (Note 4) may be furnished provided such pipe complies with all other requirements of this specification. Pipe ordered under this specification is intended for ordinary uses in steam, water, gas, and air lines, but is not intended for close coiling or bending, or high-temperature service. No mechanical tests are specified on pipe made to this specification, except hydrostatic tests which shall be made by the manufacturer, as this specification is intended to cover pipe purchased mainly from jobber’s stocks.

NOTE 1—The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as “nominal diameter,” “size,” and “nominal size.”

NOTE 2—When chemical analysis limits, tension, flattening, or bend tests are required, pipe should be ordered in accordance with Specification A 53. In the case of galvanized pipe so ordered, the base metal shall be made and tested in accordance with specification A 53 and the pipe shall be galvanized and the coating tested in accordance with this Specification A 120. When specified, results of the mechanical tests on the base material shall be reported to the purchaser.

NOTE 3—When galvanized pipe, as covered by this specification, is bent or otherwise fabricated to a degree that causes the zinc coating to stretch or compress beyond the limit of elasticity, some flaking of the coating may occur.

NOTE 4—A comprehensive listing of standardized pipe dimensions is contained in B36.10.

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