Cajon fittings were used, as they were the only manufacturer to certify their. Cajon (Swagelok), Parker, and Hoke all can supply Stainless Steel tube fittings for this application. Tube sizes is expressed in inch or millimeter, it is actual value, the actual physical OD of a tube is just the same as it’s nominal OD in both outside diameter and wall thickness, tube dimension in wall thickness is not expressed by Schedule Numble, see more tube size chart. C.3 FITTINGS C.3-1 TUBE FITTINGS Several suppliers of tube fittings will meet the required 7000-psig design pressure for 1/4-in., 3/8-in., and 1/2-in. In general, NPS is a pipe sizes number which refers to a nominal diamter, not actual diamter as specified above, the actual physical OD is larger than it’s nominal OD, and schedule number is for pipe thickness mentioned, pipe can be measured by inside diameter, because pipe is used to transportation fluid, it needs to calculate relevant parameter。 = 14″(355.6 MM, 14 x 25.4 mm)ĭifference Between Pipe And Tube Dimension Pipe inside diameter is defined by outside diameter and Schedule.When NPS over and including 14, pipe OD should actual dimension, for example, NPS20 inch, the diameter should be 508 mm, it convert inch to mm by multiplying it with 25.4.From NPS 1/8 to NPS 12 (including) the value is nominal, not actual OD, for example, NPS 6 inch (DN150), pipe outside diameter should be 168.3 mm, not 152.4 mm.NPS and DN value are different, they have a corresponding value for outside diameter in millimeter, when NPS ≥ 4, the related DN = 25 multiplied by the NPS number.SUMMARY: from above table, we can see that: Nominal Pipe Size, Diameter Nominal and pipe Schedule ChartĪSME B36.19 indicates Stainless Steel Pipe dimensions including the outside diameter and the Schedule wall thickness, the Schedule Number has an “ S” suffix for wall thickness, having SCH 5S, SCH 10S, SCH 40S, SCH 80S.ĪSME B36.10 standard determines carbon steel pipe dimensions, without an “S” suffix for pipe schedule.

The European ISO system is also OD based, Diameter Nominal (DN) is also frequently referred to pipe dimensions, it provides almost the same OD as the ANSI system, but measured in millimeters, and with a lot more choices for different wall thickness. Wall thickness referred to as the Schedule ( Sch.), nowadays, there are large selection of wall thicknesses to meet all applications under different pressure, standard weight (STD), extra-strong (XS), and double extra-strong (XXS) is three main number for thickness, 5S and 10S are thinner wall thickness for stainless steel pipe. NB (Nominal Bore) is also another method to refer pipe sizes and dimensions, it is the same value between NB and NPS. The North American ANSI system is widely applied in pipe system, Nominal Pipe Size ( NPS) is defined standard sizes for pipes used for different pressures and temperatures, the outside diameter is used in inches, NPS and OD values are not always equal, from NPS ⅛ to 12 inch, the NPS and OD values are different, over 14 inch, the NPS and OD values are equal, the size is actual dimensions, not nominal.
