Butt-Welding Concentric and Eccentric Reducer

Butt-Welding Concentric and Eccentric Reducer

Pipe Reducer is a kind of industrial pipe fittings used to connect two pipes (or tubes) of different diameters.

It contains concentric reducer and eccentric reducer. The former is used on vertical pipes, and the latter is used for horizontal pipes.
Pipe reducers are mainly used in the following areas:
1. Pipe reducer is useful when there is a requirement on change of fluid flow rate.
2. It is used for pump inlet to prevent cavitation.
3. It is fit for the connectors of instruments, such as flowmeter and control valve.
