Welded and Seamless Wrought Steel Pipe
|Publication Date:||1 January 1975|
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 tube to apply to tubular products of dimensions common· ly used for pipeline and piping systems. Pipe dimensions of sizes 12 inch and smaller have outside diameters numerically larger than corresponding size. In contrast, the outside diameters of tubes are numeri· cally identical to the size number for all sizes.
