ASME B36.10M:2000 pdf download.WELDED AND SEAMLESS WROUGIT STEEL PIPE.
ASME B36.10M 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 numencally larger than their corresponding sizes. In Contrast. the outside diameters of tubes are numerically identical
o the size number for all sizes.
2 SIZE
The sizc of all pipe is identified by the nominal pipe size.
The manufacture of pipe NPS ‘8 (DN 6) to NPS 12 (DN 300) inclusive is based on a standardiied outside diarneter (OD). This 01) was originally selected so that ppe with a standard 01) 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 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 (he 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 are given in Table 1.
5 WEIGHTS
The nominal weights of steel pipe are calculated values and are tabulated in Table I.
8 WALL THICKNESS DESIGNATIONS
The wall thickness designations Standard, Extra- Strong, and Double Extra-Strong have been comrnerdaily used designations for many years. As explained in the Foreword, (he Schedule Numbers were Subsequently added as a convenient designation for use in ordering pipe. Standard and Schedule 40 are identical for up to NPS 10 (DN 250) inclusive. All larger sizes of Standard have /g in. (9.53 mm) wall thicknesses. Extra-Strong and Schcdule O are identical for up to NPS 8 (DN 200) inclusive. All larger sizes of Extra-Strong have in. (12.70 mm) wall thicknesses.
Pipe of sizes and wall thicknesses other than those of Standard. Extra-Strong, and Double Extra-Strong, and Schedule Number were adopted from API Specification 5L. It was not considered practical to establish Schedule Numbers or new designations for them.
9 WALL THICKNESS SELECTION
Whcn the selection of wail thickness depends primarily upon capacity to rcsist internal pressure under given conditions, the designer shall compuie the exact value of wall thickness suitable for conditions for which (he pipe is required, as prescribed in detail in the ASME Boiler and Pressure Vessel Code, ASME 83? Code for Pressure Piping. or other similar codes, whichever governs the construction. A thickness shall be selected from Table I to suit the value compwed to fulfill the conditions for which the pipe is desired.ASME B36.10M pdf download.
