PVC-sheathed MICC cable. Conductor cross section area is 1.5 mm 2; overall diameter is 7.2 mm. Mineral-insulated cables at a panel board. Mineral-insulated copper-clad cable is a variety of electrical cable made from copper conductors inside a copper sheath, insulated by inorganic magnesium oxide powder.
A concentric reducer is used to join pipe sections or tube sections on the same axis. [1] The concentric reducer is cone -shaped, and is used when there is a shift in diameter between pipes. [ 1 ] For example, when a 1" pipe transitions into a 3/4" pipe and the top or bottom of the pipe doesn't need to remain level. [ 2 ]
A bronze casting showing the sprue and risers. A riser, also known as a feeder, [1] is a reservoir built into a metal casting mold to prevent cavities due to shrinkage.Most metals are less dense as a liquid than as a solid so castings shrink upon cooling, which can leave a void at the last point to solidify.
A reducer reduces the pipe size from a larger to a smaller bore (inner diameter). Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. [15] This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The reduction length is usually equal to the ...
Eccentric reducers are used at the suction side of pumps to ensure air does not accumulate in the pipe. The gradual accumulation of air in a concentric reducer could result in a large bubble that could eventually cause the pump to stall or cause cavitation when drawn into the pump. Eccentric reducers exhibit a unique design with one side having ...
Using this thicker brass may reduce the internal capacity of the cartridge and may cause excessive chamber pressures. Use appropriate caution when reloading converted rifle brass. Alternately, reloaders can purchase proper, new cases from Starline Mfg. Use .308" or .309" bullets for reloading for the Tokarev TT-33 and Czech CZ-52 .
A Jones reductor is a device used to reduce aqueous solutions of metal ions. The active component is a zinc amalgam . [ 1 ] Jones reductors have been used for preparing solutions of titanium (III), vanadium (II), chromium (II), molybdenum (III), niobium (III), europium (II), and uranium (III).
These threads are now used in materials other than steel and brass, including PTFE, PVC, nylon, bronze, and cast iron. The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other, as opposed to parallel/straight thread fittings or compression fittings in which the threads merely hold ...
