The standard pipe dimension tables shown above are valid for most of the pipe materials including the pipes made up of wrought iron, wrought steel, stainless steel, polyvinyl chloride (PVC) and CPVC. Engineering Data Table Specification 5C3 of the American Petroleum Institute standardizes 14 casing sizes from 4.5 inches (11.43 cm) to 20 inches (50.80 cm) outside diameter. Nominal Bore (NB) is another equivalent designation of NPS. CTS is based on the nominal size of a pipe. The ID size is referred to as CTS, which stands for copper tube size. In our industry, pipes and tubing are sized in two ways: By the outer diameter (OD) for smaller fittings measuring 1/4, 3/8, or 1/2 inch.

The NPS system is American designation of pipes and DN is the European counterpart of it.Īnother older designation called Iron Pipe Size (IPS) is equivalent to the NPS designation. How to determine fitting size from pipe dimensions. Wall Thickness for Pipe from Schedule 100 to XXSĪpart from the wall thickness, other pipe sizing parameters such as outer diameter of standard size pipes and NPS to DN conversion is also shown in the above tables. Table 2: Wall Thickness Table for Standard Pipe Sizes from Schedule 100 to XXS NPS Table 1: Wall Thickness Table for Standard Pipe Sizes from Schedule 5 to XS The chart is in compliance with ANSI B36.10M and API 5L.

The wall thickness unit shown in the table without bracket is in metric system i.e., millimetres ( mm), the British equivalents dimensional conversion i.e., inch is shown in bracket. Wall thickness of pipes available in different standard schedules (SCH.) for NPS (Nominal Pipe Size in “inch”) as well as DN (Diameter Nominal in “mm”) are shown in below chart.
