ASME B36.10M 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 tubeto apply to tubular products of dimensions commonlyused for pipeline and piping systems. Pipe NPS 12(DN 300) and smaller have outside diameters numeri-cally larger than their corresponding sizes. In contrast,the outside diameters of tubes are numerically identicalto the size number for all sizes.
The size of all pipe is identified by the nominalpipe size.
The manufacture of pipe NPs ‘4 (DN 6)to NPS12 (DN300)inclusive is based on a standardizedoutside diameter (OD).This OD was originally selectedso that pipe with a standard oD and having a wallthickness that was typical of the period would havean inside diameter (iD) approximately equal to thenominal size.Although there is no such relation betweenthe existing standard thickness -oDand nominalsize – these nominal sizes and standard ODs continuein use as “standard.””
The manufacture of pipe NPS l4 (DN350)andlarger proceeds on the basis of an OD correspondingto the nominal size.
The dimensional standards for pipe described hereare for products covered in ASTM specifications.
4 wALL THICKNESS
The nominal wall thicknesses are given in Table l.
The nominal weights of steel pipe are calculatedvalues and are tabulated in Table 1.
