Eccentric reducer with concentric reducer differences and similarities

Concentric reducer and eccentric reducer is what are the differences and similarities? Online explained: "the pipe gas phase medium will produce liquid; the liquid medium can produce gas, concentric reducer and eccentric reducer differences is that both reach the purpose of the variable diameter; and achieve the goal of the discharged liquid or gas. So according to your technical requirements come in the direction of the liquid or gas to choose concentric reducer and eccentric reducer."

First of all, the combination of both is: variable diameter, is the need to from a specification to another specification. However, because of different environment and medium with concentric and eccentric again, like a tee. Concentric reducer can not say, eccentric reducer says below:
1, the accumulation of gas pipeline, because of gas in the pipe can accumulate upward, so must use top flat eccentric prevent gas cannot be ruled out;
2, some impurities or effusion sinks to the pipe, so must use eccentric bottom flat, prevent accumulation cannot be ruled out
Since is a variable diameter, so, of course, is to use in the place where need specification change, otherwise you can't even; If any change, may cause the material waste and insufficient flow and so on
However, concentric reducer used no restrictions; Eccentric reducer generally will be set at pump equipment, specific see the situation.
One is not to say, is the pipe diameter change. Eccentric is divided into top and bottom flat.
Top flat generally used in liquid pipelines, prevent pipeline with pneumatosis. Bottom flat generally used in gas pipeline, prevent pipeline with effusion, and is to prevent impurities accumulated in size. There is pump imported with top flat is to prevent cavitation.
Reducer using a variety of fields
A, mine, the application of the coal industry
(1) mine: mining, ore concentrate and tailings filling transported to tube wear serious, using Ore powder conveying pipelines such as panzhihua, daye mine service life is less than a year, to increase the tube can make the life.
(2) coal: coal preparation and long distance pipeline of wet method widely used coal conveying, requires the duct is wear resistant and corrosion resistant, using the tube can be used as a long duct, considerable economic benefit.
The application of the two, metallurgy, electric power industry
Conveying of pulverized coal, metallurgy, electric power industry ash, mud and lime gypsum slurry every year to spend a lot of metal pipe. By using ceramic pipe to replace other pipe has high wear resistance, long service life, easy installation, the economic benefit is remarkable characteristic.
