ASME B36.10M:2000 pdf free download – WELDED AND SEAMLESS WROUGHT STEEL PIPE
1SCOPE
This Standard covers the standardization of dimen- sions of welded and seamless wrought steel pipe for high or low temperatures and pressures. The word pipe is used as distinguished from rube to apply to tubular products of dimensions commonly used 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 identical to the size number for all sizes.
2 SIZE
The size of all pipe is identified by the nominal pipe size. The manufacture of pipe NPS (DN 6) to NPS 12 (DN 300) inclusive is based on a standardized outside diameter (OD). This OD was originally selected so that pipe with a standard OD and having a wall thickness that was typical of the period would have an inside diameter (ID) approximately equal to the nominal size. Although there is no such relation between the existing standard thickness – OD and nominal size – these nominal sizes and standard ODs continue in use as “standard.” The manufacture of pipe NPS 14 (DN 350) and larger proceeds on the basis of an OD corresponding to the nominal size.
3 MATERIALS
The dimensional standards for pipe described here are for products covered in ASTM specifications.
4 WALL THICKNESS
The nominal wall thicknesses are given in Table I.
5 WEIGHTS
The nominal weights of steel pipe are calculated values and are tabulated in Table 1.
6 PERMISSIBLE VARIATIONS
Variations in dimensions differ depending upon the method of manufacture employed in making the pipe to the various specifcations available. Permissible varia-tions for dimensions are indicated in each specification.
7 PIPE THREADS
Unless otherwise specifed, the threads of threaded pipe shall conform to ANSI/ASME B1.20.1， Pipe Threads, General Purpose (Inch).Schedules 5 and 10 wall thicknesses do not permit threading in accordance with ANSUASME B1.20.1.
