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 ...
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 ...
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 ]
Galvanized steel potable water supply and distribution pipes are commonly found with nominal pipe sizes from 3 ⁄ 8 inch (9.5 mm) to 2 inches (51 mm). It is rarely used today for new construction residential plumbing.
As of 1955 it was getting replaced in Soviet service by the T-12 antitank gun and the 85 mm antitank gun D-48. A number of BS-3 pieces are still stored in Russian Ground Forces arsenals. In 2012, at least 12 BS-3 guns were still active with the 18th Machine Gun Artillery Division , located on the Kuril Islands , used as anti-ship and anti ...
The screw lengths for parts C, D and E become whole numbers when adding a 2.6 mm thick bracket (which is how the standard describes them). [2] The screw lengths for part F are minimum / maximum / hole maximum, as in: M6 screws must go at least 9 mm in but at most 10 mm in, and the hole might not be deeper than 12 mm. [2]
In Romanian Army service, the A407 is known as the 100 mm anti-tank gun M1977 (Romanian: Tun antitanc calibrul 100-mm Model 1977) and is normally towed by the DAC 887R truck. [32] It can also be towed with the DAC 665T truck. The Model 2002 is an improved version, fitted with the automatic fire control system TAT-100. [33]
