3. Tube (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Tube_(fluid_conveyance)

   Both pipe and tube imply a level of rigidity and permanence, whereas a hose is usually portable and flexible. A tube and pipe may be specified by standard pipe size designations, e.g., nominal pipe size, or by nominal outside or inside diameter and/or wall thickness. The actual dimensions of pipe are usually not the nominal dimensions: A 1-inch ...

   en.wikipedia.org/wiki/Drawing_(manufacturing)

   Push Pointing: Several inches of the lead ends of the bar or tube are reduced in size by swaging or extruding so that it can pass freely through the drawing die. This is done because the die opening is always smaller in size than the original bar or coil section. Cold drawing, process drawing: In this process, the material is drawn at room ...

   For pipe sizes of NPS 14 inch (DN 350) and greater the NPS size is the actual diameter in inches and the DN size is equal to NPS times 25 (not 25.4) rounded to a convenient multiple of 50. For example, NPS 14 has an OD of 14 inches or 355.60 millimetres, and is equivalent to DN 350.

   3.3 Type S—Seamless, Grades A and B. Note: Type F is not intended for flanging. If Type S or Type E is required for close coiling or cold bending, Grade A is the preferred grade; however, this is not intended to prohibit the cold bending of Grade B pipe. Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer. 4.

7. 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 ...

   en.wikipedia.org/wiki/Copper_tubing

   While pipe sizes in Australia are inch-based, they are classified by outside rather than inside diameter (e.g., a nominal 3 ⁄ 4 inch copper pipe in Australia has measured diameters of 0.750 inches outside and 0.638 inches inside, whereas a nominal 3 ⁄ 4 inch copper pipe in the U.S. and Canada has measured diameters of 0.875 inch outside and ...
