The cone-shaped concentric pipe reducer means the pipes have matched center lines, and the eccentric reducer has mis-matched center lines. Both of these have a consequence regarding flow. Most reducers are going to be concentric. Eccentric reducers are used when the pipes have to maintain the same top or bottom level. Eccentric reducers are frequently used to avoid trapping air within the system, so they are often used when both air and liquids may be flowing together.
An eccentric reducer is a fitting used in piping systems between two pipes of different diameters. The same fitting can be used in reverse as an eccentric increaser or expander. They are used where the diameter of the pipe on the upstream side of the fitting (where flow is coming from) is larger than the downstream side, and where there is a danger that vapour may accumulate. Unlike a concentric reducer, which resembles a cone, eccentric reducers have an edge that is parallel to the connecting pipe, referred to as the flat side. This parallel edge results in the two pipes having offset center lines. Because eccentric reducers are asymmetrical, they create asymmetrical flow conditions; flow is faster along the angled side, resulting in increased pressure.
