What is the use of reducer in piping?

The JS  carbon steel seamless eccentric reducer is a fitting used in piping systems between two pipes of different diameters. Reducers are used in where the diameter of the pipe on the upstream side of the fitting (i.e. where flow is coming from) is larger than the downstream side. Unlike a concentric reducer, which resembles a cone, eccentric reducers have an edge that is parallel to the connecting pipe. This parallel edge results in the two pipes having offset center lines. The same fitting can be used in reverse as an eccentric increaser/expander.

Horizontal liquid reducers are always eccentric, top flat (unless on control set, same as PV, TV, HV, LV) or (pipe rack), which prevents the build up of air bubbles in the system. 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.

Horizontal gas reducers are always eccentric, bottom flat, which allows condensed water or oil to drain at low points.

Reducers in vertical lines are generally concentric unless the layout dictates otherwise.

Can your price be lower?
Of course. The thickness tolerance of the pipe fittings is ±12.5%, the thickness tolerance of the forged flanges is ±1mm. If the bigger tolerance is acceptable for you, the price can be lower. If you must need the products with standard tolerance, please consider to add the quantity, the more the cheaper.
