l scoPE
This Standard covers the standardization of dimensionsof welded and seamless wrought steel pipe for high or lowtemperatures and pressures.
The word “pipe” is used,as distinguished from “tube”, toapply to tubular products of dimensions commonly usedfor pipeline and piping systems.
2 SIZE
The size of all pipe in Table 2-1 is identified by thedimensionless designator nominal pipe size (NPs)[diametre nominal (DN)]. Pipe NPS 12 (DN 300) andsmaller have outside diameters numerically larger thantheir corresponding sizes.In contrast, the outsidediameters of tubes are numerically identical to the sizenumber for all sizes.
The manufacture of pipe NPs 1/ (DN 6) to NPS 12 (DN300),inclusive, is based on a standardized outsidediameter (O.D.). This o.D. was originally selected sothat pipe with a standard o.D.and having a wall thicknessthat was typical of the period would have an insidediameter (1.D.) approximately equal to the nominalsize.Although there is no such relation between theexisting standard thickness — 0.D. and nominal size —these nominal sizes and standard o.D.s continue in useas “standard.”
The manufacture of pipe NPS 14 (DN 350) and larger isbased on the o.D. being the same as the nominal pipe size.3REFERENCES

4 MATERIALS
The dimensional standards for pipe described in thisStandard are for products covered in ASTM specifications.5 WALL THICKNESS
The nominal wall thicknesses are given in Table 2-1.6 WEIGHTS/MASSEs
The nominal weights (masses) of steel pipe are calcu-lated values and are given in Table 2-1.
The nominal plain end weight, in pounds per foot,iscalculated using the following equation:
wpe = 10.69(D – t)t
where
D = outside diameter to the nearest 0.001 in.for NPS
8 and smaller, to the nearest 0.01 in. for NPS 10to NPS 30, inclusive, and to the nearest 0.1 in. forNPS32 and larger (the symbol D is to be used foro.D. only in mathematical equations orformulas)
t = specified wall thickness, rounded to the nearest
0.001 in.
wpe = nominal plain end weight,rounded to the
nearest 0.01 lb/ft
The nominal plain end mass, in kilograms per meter, iscalculated using the following equation:
Mpe = 0.0246615(D – t)t
where
D = outside diameter to the nearest 0.01 mm for DN
200 and smaller, to the nearest 0.1 mm for DN250 to DN 750, inclusive, and to the nearest 1mm for DN 800 and larger (the symbol D is to beused for O.D. only in mathematical equations orformulas)
Mpe = nominal plain end mass, rounded to the nearest
0.01 kg/m
t = specified wall thickness, rounded to the nearest
0.01 mm
7 PERMISSIBLE VARIATIONS Variations in dimensions differ depending upon the method of manufacture employed in making the pipe to the various specifications available. Permissible varia- tions for dimensions are indicated in each specification.
8 PIPE THREADS Unlessotherwisespecified,thethreadsofthreadedpipe shall conform to ASME B1.20.1. Schedules 5 and 10 wall thicknesses do not permit threading in accordance with ASME B1.20.1.
9 WALL-THICKNESS DESIGNATIONS The wall-thickness designations standard (STD), extra- strong (XS), and double extra-strong (XXS) have been commercially used designations for many years. As explained in the Foreword, the Schedule numbers were subsequently added as a convenient designation for use in ordering pipe. Standard and Schedule 40 are iden- tical up to NPS 10 (DN 250), inclusive. All larger sizes of STD have 3 ∕ 8 in. (9.53 mm) wall thicknesses. XS and Sched- ule 80 are identical up to NPS 8 (DN 200), inclusive. All larger sizes ofXS have 1 ∕ 2 in. (12.70 mm) wall thicknesses. Pipe of sizes and wall thicknesses other than those of STD, XS, and XXS, and Schedule number were adopted from API 5L. It was not considered practical to establish Schedule numbers or new designations for them.
10 ð22Þ WALL-THICKNESS SELECTION When the selection ofwall thickness depends primarily upon capacityto resistinternal pressure undergiven con- ditions, the designershall compute the value ofwall thick- ness suitable forconditions forwhich the pipe is required, as prescribed in detail in the ASME Boiler and Pressure Vessel Code, ASME B31 Code for Pressure Piping, or other similar codes, whichever governs the construction. A thickness may be selected from Table 2-1 that is suitable for the conditions for which the pipe is required.
