1.1This specification covers hot-dipped galvanized welded steel pipe in sizes ranging from 1.315-8.625 in. (33.4 - 219.1 mm) outside diameter (OD) inclusive, with nominal (average) wall thickness as given in Table 1 and Table 2. Pipe having other dimensions (Note 2) may be furnished provided such pipe complies with all other requirements of this specification. Pipe ordered under this specification is intended for use as a structural support for fencing in accordance with Specification F1043, Group 1A.

TABLE 1 Dimensions, Nominal Weights (Plain Ends) for Standard Weight Pipe (Schedule 40)

Note 1-Pipe furnished in accordance with this table will be standard pipe. Nominal size designations are names, not dimensions, thus they are a unit-less term. The dimensionless designator NPS (nominal pipe size) is referenced in this specification as it is the historical designation for schedule 40 pipe. The fence framework application requires the framework fittings to fit securely on the outside of the pipe and therefore the OD, outside diameter, is the applicable dimension for this specification.

Note 2-The wall thickness is expressed in three decimal places, the fourth decimal place being carried forward or dropped, in accordance with Practice E29.

TABLE 2 Dimensions, Nominal Weights (Plain Ends) for Extra Strong Pipe (Schedule 80)

Note 1-Pipe furnished in accordance with this table will be extra-strong pipe. Nominal size designations are names, not dimensions, thus they are a unit-less term. The dimensionless designator NPS (nominal pipe size) is referenced in this specification as it is the historical designation for schedule 80 pipe. The fence framework application requires the framework fittings to fit securely on the outside of the pipe and therefore the OD, outside diameter, is applicable dimension for this specification.

Note 2-The wall thickness is expressed in three decimal places, the fourth decimal place being carried forward or dropped, in accordance with Practice E29.
