ASME B36.19M:2004 pdf download.Stainless Steel Pipe.
ASME B36.19M covers the standardization of dimensions of welded and seamless wrought stainless steel pipe for high or low temperatures and pressures.
The word pipe is used, as distinguished from lub4’, to apply to tubular products of dimensions commonly used for pipeline and piping systems. Pipes 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.
The wall thicknesses for NI’S 14 through 22, inclusive (DN 350—550, inclusive), of Schedule 105; NI’S 12 (DN 300) of Schedule 405; and NI’S 10 and 12 (DN 250 and
300) of Schedule 805 are not the same as those of ASME B36.IOM. The suffix “S” in the schedule number is used to differentiate H36.19M pipe from 1i36.1OM pipe. ASME B36.IOM includes other pipe thicknesses that are aL%o commercially available with stainless steel material.
2 SIZE
The size of all pipe in Table I is identified by the nominal pipe size.
The manufacture of pipe NI’S ‘4 (DN 6) through NI’S 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 thicknesses — OD and nominal size — these nominal sizes and standard ODs Continue in use as “standard.”
The manufacture 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.
6 PERMISSIBLE VARIATIONS
Variations in dimensions differ depending upon the method of manufacture employed in making the pipe to the various specifications available, Pennissible variations for dimensions are indicated in each specification.
7 PIPE THREADS
Unless otherwise specified, the threads of threaded pipe shall conform to ANSI/ASME B1.20.1, Pipe Threads, General Purpose (Inch).
