While similar standards exist for specific industry application tubing, tube is often made to custom sizes and a broader range of diameters and tolerances. Many industrial and government standards exist for the production of pipe and tubing. The term "tube" is also commonly applied to non-cylindrical sections, i.e., square or rectangular tubing.
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 ...
An inner tube is an inflatable torus that forms the interior of some pneumatic tires. [1] The tube is inflated through a valve stem and fits inside the tire casing. The inflated inner tube provides structural support and suspension, while the outer tire offers grip and protects the more fragile tube.
A separate airtight inner tube enclosed by the tire supports the tire carcass and maintains the bead lock. An advantage of this system is that the inner tube can be easily accessed for a patch repair or replacement of the tube. The ISO 5775-2 standard defines designations for bicycle rims. It distinguishes between Straight-side (SS) rims
There is the rare exception of metric-diameter tires, such as the use of the 390 size, which in this case would indicate a rim of 390 mm in diameter. Few tires are made to this size currently. The number may be longer where a half-inch size is used, for example many heavy transport trucks now use 22.5-inch tires. [7] [8]
AN sizes range from -2 (dash two) to -32 in irregular steps, with each step equating to the OD (outside diameter) of the tubing in 1 ⁄ 16-inch increments. Therefore, a -8 AN size would be equal to 1 ⁄ 2-inch OD tube. However, this system does not specify the ID (inside diameter) of the tubing because the tube wall can vary in thickness.
The iron pipe size standard came into being early in the 19th century and remained in effect until after World War II. The IPS system was primarily used in the United States and the United Kingdom. In the 1920s, the Copper Tube Size (CTS) standard was combined with the IPS standard.
The larger diameter of the head tube and headset gives added stiffness to the steering portion of the bicycle. Common sizes. 25.4 mm (1 in) steerer tube, this may have a fork crown (the base of the fork steerer tube) of a number of different dimensions, and milling may be necessary to make some headsets fit. 26.4 mm crown race (ISO standard)
