This specification covers hot-dipped zinc-coated (galvanized) welded steel pipe in NPS 1, NPS 1 ?, NPS 1 ?, NPS 2, NPS 2 ?, NPS 3, NPS3 ?, NPS 4, NPS 5, NPS 6, NPS 7, and NPS 8, with the specified nominal wall thickness, intended for fence structures such as structural support. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification. The steel for welded pipe shall be be of soft weldable quality and shall be made by one or more of the following processes: electric-furnace, open hearth, or basic oxygen. Welded pipe NPS 4 and under may be butt-welded. Welded pipe over NPS 4 shall be electric welded. Pipe shall be coated with zinc inside and outside by hot-dip process. The steel pipe shall meet the tensile requirements for tensile strength and yield strength specified for regular, intermediate strength, and high strength grades. The weight of zinc coating shall be determined by strip test. The dimensional (diameter and thickness) and weight requirements for the steel pipe are specified and the test requirements for welded pipes are detailed. Lengths of toprail may be of random lengths, unless otherwise specified.
