a pipe, 5 the pipe outside diameter (OD) and wall thickness can be obtained from reference tables such as those below, which are based on asme standards B36.10Mand B36.19M. This will result in the concept of the schedule number that combines wall thickness and diameter of the pipe. The European and international designation equivalent to NPS. It was originally intended for these to be phased out, but they occasionally appear.

For each nominal pipe size, the outside diameter (O.D.) remains relatively constant; the variations in wall thickness affect only the inside diameter (I.D.). 160 XXS.500 (114.30).083 (2.108).120 (3.048).188 (4.775).237 (6.020).337 (8.560).437 (11.100).531 (13.487).674 (17.120) 4 115.000 (127.00).247 (6.274).355 (9.017).710 (18.034) 5 125.563 (141.30).109 (2.769).134 (3.404).258 (6.553).375 (9.525).500 (12.700).625 (15.875). See pipe dimensional table, Specification asme B36.10M or B36.19M for pipe dimensions per schedule. As stated above, they are measured with nominal outside diameters using NPS and Schedule to define the pipe size. XS is identical to SCH 80S, and 80S is identical to 80 for NPS 1/8 to NPS 8, inclusive. Under asme B36.19 Schedule no with S suffix is introduced for SS pipe. Manufacturing of NPS 14 (DN350) and above pipe OD is corresponding to the Nominal Size of a pipe. Although it is related to the outside diameter, it is significantly different. API American Petroleum Institute, nPS Nominal Pipe Size,.D. References edit "astm A999 / A999M - 14 Standard Specification for General Requirements for Alloy and Stainless Steel Pipe". Description Size Over Under Weight NPS 12 (DN 300) and under.50 Weight NPS 14 (DN 350) and above (Note-1) 10 5 Wall Thickness Seamless and Welded Pipe 18 to 2, incl., all t/D ratios (Note-2).00.50 3 to 18 incl., t/D. Standardization of wrought steel Pipe schedule and pipe sizes begin with mass production era. To understand this concept, you have to learn the way pipes are manufactured. For sizes from 1/8-inch through 12-inch, the NPS corresponds to the nominal inside diameter, but differs somewhat from its actual inside diameter. 22.50.50 20 and larger, seamless, t/D.00.50 Forged and Bored Pipe 1/8.(3.2mm) Nil Cast Pipe 1/6.(1.6mm) Nil Inside Diameter for Cast Pipe Nil 116. (9.53 mm) XS has same thickness as Schedule 80 for up to NPS 8 (DN 200) Above NPS 8 XS have a wall thickness. With below example, you have more clarity of the concept. In current practice, pipe size defines with two sets of number 1) Pipe bore/nominal diameter and 2) Pipe schedule which is nothing but wall thickness of the pipe. Understanding Pipe Schedule Terminology, while the Nominal Pipe Size identifies the outside diameter of the pipe, more information is needed to identify specific pipes. There is no change in other dimensions when you use. OD and Nominal Pipe Size, tubing is measured by the outside diameter (O.D. Nominal Pipe Sizes apply to all materials of pipe. In simple word you can say that for given material, schedule 40 pipe can withstand a certain amount of pressure. However stainless steel pipe can also be available in other schedules. A Some specifications use pipe schedules called standard wall (STD extra strong (XS and double extra strong (XXS although these actually belong to an older system called iron pipe size (IPS).

This article is about the.S.Standard for pipe sizes, abbreviated NPS.
Pipes are identified by Diametre Nominel DN which is a dimensionless value that roughly equates to the outside diameter of the pipe. The term NB nominal bore is also frequently used interchangeably with NPS. The wall thickness of tubing is measured in inches 2, s Mohinder, misalignment, in addition to the schedule numbers. The term, an NPS article 14 size pipe is actually 14 inches 360 mm.
