ASME B36.19M-2004 Stainless Steel Pipe

An American National Standard. The American Society of Mechanical Engineers (ASME). Revision of ANSI/ASME B36.19M-1985. Date of Issuance: October 25, 2004. 14p. This Standard 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 tube, 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
