These are also referenced as a hollow structural section or HSS for short. All Rights Reserved. Connect duct hose to exhaust systems or … Find Out More. 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. Let Penn Stainless cut your next seamless tubing requirement to your exact dimension. 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, … In stock and ready to ship. Pipe. Stainless steel tube is commonly used for structural applications and has more exact tolerances than stainless steel pipe. Vita offers small diameter tubing in a wide range of materials including stainless steel, aluminum, brass, nickel, and copper. Stainless Steel Pipe Chart. ), 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. Stainless Round Tubing. SUMMARY: from above table, we can see that: 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。. We stock a wide range of diameters and wall thicknesses. 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.
