What Is A Concentric Reducer For Pipe?

Carbon Steel Concentric Reducer Dimensions based on the needs of the application, the connecting pipe, the material, standards and pressure classes. The Asme B16.9 Reducer belongs to a standard of pipe fittings that range from NPS ½ to NPS 48. The Asme B16.9 Reducer Dimensions differ in due to their shape greatly than the Asme B16 9 Eccentric Reducer Dimensions due to the cone shaped reduction in the Asme B16 9 Concentric Reducers. The eccentric reducers have one side of the reducer aligned with the pipe’s length where other side is reduced from the supplying pipe to the receiving pipe. The Carbon Steel Concentric Reducer Asme B16.9 Dimensions do not differ in that way.

What Is The Difference Between Concentric And Eccentric Reducer?

  • The Stainless Steel Concentric Reducer B16.9 is stronger and is used in many applications where the nominal pipe size is less than 48 inches. There are different materials used to produce the reducer and there are different types as well.

  • The SS Eccentric Reducer is affordable and could be used in low cost applications. The applications include the water supply lines, domestic piping, sea water desalinization plants, waste water management facilities and other low cost applications.


Why Concentric Reducer Used In Pump Suction?

The main categories are type A and type B. The Concentric Reducer Type B has a full load factor where the type A has a reduced load factor. The Ansi B 16.9 Concentric Reducer is used in high pressure applications where the pressure has to be tolerated and the load is often full. The latest standards such as Concentric Reducer En 10253 2 cover the buttweld concentric reducer properties and quality. Any piping that has a need for high pressure full load reduction can use the Concentric Reducer Fitting. Rajtilak Metal is one of the leading Concentric Reducer Manufacturers in India.

ASME B16.9 Carbon Steel Concentric Reducer

The axis is kept the same without an offset and therefore the fluid flow is directed through the same axis with only a reduction in volume and in a consistent way. The Carbon Steel Concentric Reducer Bw is strong through the buttwelding and is used to gradually increase pressure over the reduction.
