ASME B36.10M:2000 pdf download.WELDED AND SEAMLESS WROUGHT STEEL PIPE.

The word pipe is used as distinguished from tube to apply to tubular products of dimensions commonly used foi pipeline and piping

systems. Pipe NPS 12 (DN 300) and smaller have outside diameters numencally larger than their corresponding sizes. In contrast. the outside diameterx 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 ‘4 (DN 6) to NPS 12 (DN 300) inclusive is based on a standardized outside diameter (01)). This 01) 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 dsameter (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 01) 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.
