2. Nominal Pipe Size - Wikipedia

   en.wikipedia.org/wiki/Nominal_Pipe_Size

   Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...

3. Iron pipe size - Wikipedia

   en.wikipedia.org/wiki/Iron_pipe_size

   Iron Pipe Size (IPS or I.P.S.) pipe sizing system based on the inside diameter (ID) of pipe. It was widely used from the early 19th century to the mid 20th century and is still in use by some industries, including major PVC pipe manufacturers, as well as for some legacy drawings and equipment.

4. Pipe (fluid conveyance) - Wikipedia

   As technology improved, thinner walls became possible, but the outside diameter stayed the same so it could mate with existing older pipe, increasing the inner diameter beyond half an inch. The history of copper pipe is similar. In the 1930s, the pipe was designated by its internal diameter and a 1 ⁄ 16-inch (1.6 mm

5. Cast iron pipe - Wikipedia

   en.wikipedia.org/wiki/Cast_iron_pipe

   This standard specified a dimensionless nominal size, which approximately corresponded with the internal diameter in inches of the pipe, and four pressure classes, Class A, Class B, Class C and Class D, each with a specified wall thickness and outer diameter.

6. Hydraulic diameter - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_diameter

   For a fully filled duct or pipe whose cross-section is a convex regular polygon, the hydraulic diameter is equivalent to the diameter of a circle inscribed within the wetted perimeter. This can be seen as follows: The N {\displaystyle N} -sided regular polygon is a union of N {\displaystyle N} triangles, each of height D / 2 {\displaystyle D/2 ...

7. Ductile iron pipe - Wikipedia

   en.wikipedia.org/wiki/Ductile_iron_pipe

   European pipe is standardized to ISO 2531 and its descendent specifications EN 545 (potable water) and EN 598 (sewage). European pipes are sized to approximately match the internal diameter of the pipe, following internal lining, to the nominal diameter. ISO 2531 maintains dimensional compatibility with older German cast iron pipes.
