ASME B36.10M-2004 pdf free download.Welded and Seamless Wrought 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 distinguiched from ?ub€, to apply to tubular products of dimensions commonly used for pipeline and piping systems. Pipe NPS 12 (DN 300) and smaller have ouide diameters numerically larger than their corresponding sizes. In contrast, the outside diameters 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 NI’S (DN 6) to 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 thickness — 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 dimencional standards for pipe described here are for products covered in ASTM specifications.
4 WALl. THICKNESS
The nominal wall thicknesses arc given in Table 1.
5 WEIGHTS
The nominal weights of steel pipe are calculated values and are tabulated in Table 1.
The nominal plain end weight, in pounds per loot, is calculated using the following formula:
6 PERMISSIBLE VARIATIONS
Variations in dimensions differ depending upon the method of manufacture employed in making the pipe to the various specifications available. Permissible 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.l, Pipe Threads, General Purpose (Inch).
Schedules 5 and 10 wall thicknesses do not permit threading in accordance with ANSI/ASME B1.20.1.
8 WALL THICKNESS DESIGNATiONS
The wall thickness designations Standard, Extra- Strong, and Double Extra-Strong have been commercially used designations for many years. As explained in the Foreword, the Schedule Numbers were subsequently added as a convenient designation for use in ordering pipe. Standard and Schedule 4k) 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 Schedule 80 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
When the selection of wall thickness depends primarily upon capacity to resist internal pressure under given conditions, the designer shall compute the exact value of wall thickness suitable for conditions for which the pipe is required, as prescribed in detail in the ASME Boiler and Pressure Vessel Code, ASME B31 Code for Pressure Piping, or other similar codes, whichever gov-
erns the construction. A thickness shall be selected from Table 1 to suit the value computed to fulfill the conditions for which the pipe is desired.
