Stainless Steel Butt Weld Eccentric Reducers

Application:Solve the problem of unbalanced water flow-Due to the different diameters of the pipes during the connection process, the water flow will be unbalanced. In this case, using an eccentric reducer can balance the water flow in two pipes with different diameters;

Reduce noise- During pipeline operation, noise caused by water flow impact is a common problem, and the use of eccentric reducers can reduce noise;

Avoid the formation of air bag- Some fire pipes use eccentric reducers for water inlets to avoid the formation of air bags and reduce damage to the water pump.Material:304 stainless steel,316L stainless steel,2205 stainless steel，etc.

Knowledge Expansion

Since one side of the eccentric large and small heads is flat, it is conducive to exhaust or liquid drainage, and is convenient for driving and maintenance. Therefore, horizontally installed liquid pipelines generally use eccentric reducers.

When the tangent point of the nozzle of the eccentric large and small heads is upward, it is called top-flat installation, which is generally used for the pump inlet, which is convenient for exhaust; when the tangent point is downward, it is called bottom-flat installation, which is generally used for the installation of regulating valves and uses drain.

There are only two types of large and small heads: concentric and eccentric. Flat top and flat bottom are just an installation method for eccentric and large heads.
