The pipe reducer is one of the pipe fittings, which is used for connecting two pipes with varying diameters. A pipe reducer is used to change rate of fluids the flow through. Reducers are usually made by reducing pressing processes, or by expanding pressing processes or by both reducing and expanding pressing processes together, and we can also adopt stamping processes for reducers with some specifications. Reducers are categorized into types, Eccentric and Concentric Reducer. The pipe reducers are widely available in a various materials as per the demands of its applications and industries and also available in different dimensions too.
The Eccentric reducers have two ends with different diameters. These reducers are to connect pipes having different flanges or diameters. An eccentric reducer pipe fitting is made with a slightly off-center outlet to the larger end. It allows it to attach to one of the inlet’s sides. This reduction systems are used where, on the upstream side of the fitting, the diameter of the pipe from which the flow originates is greater than on the downstream side. The Eccentric reducers are conducive to liquid flows, and it has less intrusion in the fluid flow when the diameter of the reducer is changed.
As a result, eccentric reducers are most often found in gas pipes and pipes with vertical fluid flow. Eccentric reducers have one flat side that is useful for discharging gases or liquids and for opening and retaining the reducer. As a result, eccentric reducers are usually used with horizontally installed fluid pipes.
Horizontal liquid reducers are usually eccentric, with a flat top that avoids the accumulation of air bubbles in the system. Eccentric reducers are used on the suction side of pumps to stop air trapping in the tubing. The gradual accumulation of air in a concentric reducer can result in a large bubble, causing the pump to stall or cavitation when drawn into the pump. Horizontal gas reducers are often eccentric with smooth bottoms, allowing condensed water or oil to drain at low stages.
Feature of Eccentric Reducer
- Eccentric reducer help to connect large diameter pipe with small diameter pipe
- Noise and vibration are reduced by using these type of reducers.
- These reducers need a limited amount of setup space.
- The eccentric reducer absorbs sounds generated by the pipe wall as well as fluid tolerated.
- This reducers have the lowest amount of turbulence entrapment.
