ASME B36.10M-2000 pdf – WELDED AND SEAMLESS WROUGHT STEEL PIPE.
This Standard covers the standardization of dimensions of welded and seamless wrought steel pipe for high or low temperatures and pressures.
The word pipe is used as distinguished from tube to apply to tubular products of dimensions commonly used for pipeline and piping systems. Pipe NPS 12 (DN 300) and smaller have outside diameters numerically 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 ‘/g (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 o 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 rnanufacwre of pipe NI’S 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 arc given in Table 1.
5 WEIGHTS
The nominal weights of steel pipe are calculated values and are tabulated in Table I.
9 WALL THICKNESS SELECTION
When (he selection of wall thickness depends primarily upon capacity (0 resist internal pressure under given conditions, the designer shall compwe the exact value of wall thickness suitable for conditions for which the pipc is required. as prescribed in detail in the ASME Boiler and Pressure Vessel Code, ASME 831 Code for Pressure Piping. or other similar codes, whichever governs the Construction. A thickness shall be selected from Table I to suit the value computed to fultill the conditions for which the pipe is desired.
