2 SIZE
The size of all pipe in Table 2-1 is identified by the dimensionless designator nominal pipe size (NPS) [dlamètre nominal (ON)). Pipe NPS 12 (ON 300) and smaller have outside diameters numerically brger than their corresponding sizes. In contrast, the outside diameters of tubes are numerically identical to the stze number for all sizes.
The manulacture ca pipe NPS 4 (ON 6) to NPS 12 (ON 300), inclusive, is based on a standardized outside diameter (00.). This OD. was originally selected so that pipe with a standard 0.1). and having a wall thickness that was typical of the period would have an inside dIameter (1.0.) approximately equal to the nominal size. Although there Is no such relation between the existing standard thickness — 0.1). and nominal size — these nominal sizes and standard 0.O.s continue in use as ‘standard.’
The manufacture of pipe NI’S 14 (ON 350) and larger proceeds on the basis of an 0.1). corresponding to the nominal size.
3 MATERIALS
The dimensional standards for pipe described here are for products covered in ASTU specifications.
4 WALL THICKNESS
The nominal wall thicknesses are given In Table 2-1.
5 WEIGHTS/MASSES
The nominal weights (masses) of steel pipe are calcubtrd values and are tabulated in Table 2-1.
The nominal plain end weight, in pounds per loot, Es calculated using the following formula.
