ASME B36.10M:2004 pdf download Welded and Seamless Wrought Steel Pipe
This Standard covers the standardization of dimen-sions of welded and seamless wrought steel pipe forhigh or low temperatures and pressures.The word pipe is used, as distinguished from fube, toapply to tubular products of dimensions commonly usedfor pipeline and piping systems. Pipe NPS 12 (DN 300)and smaller have outside diameters numerically largerthan their corresponding sizes. In contrast, the outsidediameters of tubes are numerically identical to the sizenumber for all sizes.
2SIZE
The size of all pipe is identified by the nominalpipe size.
The manufacture of pipe NPS %(DN 6) to NPS 12(DN 300), inclusive, is based on a standardized outsidediameter (OD).This OD was originally selected so thatpipe with a standard OD and having a wall thicknessthat was typical of the period would have an insidediameter (ID) approximately equal to the nominal size.Although there is no such relation between the existingstandard thickness — OD and nominal size – thesenominal sizes and standard ODs continue in use as”standard.”
The manufacture of pipe NPS 14 (DN 350) and largerproceeds on the basis of an OD corresponding to thenominal size.
MATERIALS3
The dimensional standards for pipe described hereare for products covered in ASTM specifications.
4 WALL THICKNESS
The nominal wall thicknesses are given in Table 1.
5 WEIGHTS
The nominal weights of steel pipe are calculated val-ues and are tabulated in Table 1.The nominal plain end weight, in pounds per foot, iscalculated using the following formula:
W= 10.69(D – t)t
where
outside diameter to the nearest 0.001 in.(the0=symbol D is to be used for OD only in mathematical equations or formulas)Wp=nominal plain end mass, rounded to the nearest 0.01 1b /ftspecified wall thickness, rounded to the near-t=est 0.001 in
The nominal plain end mass, in kilograms per meteris calculated using the following formula:
Wx=0.0246615(D -f)f
whereDoutside diameter to the nearest 0.1 mm foroutside diameters that are 16 in.(406.4 mm)and smaller and to the nearest 1.0 mm foroutside diameters larger than 16 in.(406.4mm) (the symbol D is to be used for OD onlyin mathematical equations or formulas)Wnominal plain end mass, rounded to the near-est 0.01 kg/mt=specified wall thickness, rounded to the nearest 0.01 mm
6 PERMISSIBLE VARIATIONS
Variations in dimensions differ depending upon themethod of manufacture employed in making the pipeto the various specifications available Permissible variations for dimensions are indicated in each specification.
7 PIPE THREADS
Unless otherwise specified, the threads of threadedpipe shall conform to ANSI/ASME B1.20.1,PipeThreads,General Purpose (Inch).
Schedules 5 and 10 wall thicknesses do not permitthreading in accordance with ANSI/ASME B1201.
8 WALL THICKNESS DESIGNATIONS
The wall thickness designations Standard, ExtraStrong, and Double Extra-Strong have been commer-cially used designations for many years. As explained inthe Foreword, the Schedule Numbers were subsequentlyadded as a convenient designation for use in orderingpipe. Standard and Schedule 40 are identical for up toNPS 10 (DN 250), inclusive. All larger sizes of Standard
