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.
Are you manufacturer or trading company?
We are true factory and manufacture costing and forged flanges since 1983, and produce pipe fittings for more than 20 years. Our factory is located in Yanshan Cangzhou City. Welcome to visit us. We are pleased to show you our advanced production lines.
Can you supply a price list of all your items?
Because the price is affected by material cost, total quantity, transportation cost and exchange rate, a draft price list is not helpful for your purchase. Please kindly supply us your purchase details, such as item name, type, size, pressure, surface treatment, quantity and destination port. We will supply you the real competitive offer.
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.
How can I confirm the quality for the first order?
1. we are professional manufacturer for so many years and have the ISO certificates.
2. We can show you pictures and videos of our bulk orders.
