ECC Reducer Dimensions

ECC Reducer information:
Eccentric reducer is used in different diameters of two pipes between the piping system accessories. They are used for the pipe diameter of the upstream side of the accessory (i.e. where the flow is coming from) larger than the downstream side. Unlike a cone-like concentric reducer, the edge of the eccentric reducer is parallel to the connecting pipe. This parallel edge causes two pipelines to have an offset centerline. The same accessory can be used as an eccentric supercharger/expander.
The horizontal liquid reducer is always eccentric, the top flat (unless in the PV,TV,HV,LV control setting) or (tube frame), to prevent the accumulation of bubbles in the system. The suction side of the pump uses an eccentric reducer to ensure that the air does not accumulate in the pipe. The gradual accumulation of air in a concentric reducer may lead to large bubbles, which eventually cause a stall or cavitation in the pump suction pump.
The horizontal pressure reducer is always eccentric, the bottom is flat, which allows condensation of water or oil to be discharged at a low point.
The reducer of the vertical line is usually concentric, unless otherwise stipulated in the layout.
