The concentric reducer china is generally used for connection. For example, the concentric reducer china at the outlet of the centrifugal pump is to connect the pipeline with the pump inlet and outlet. The inlet is generally larger and smaller, and the outlet is generally smaller and larger.

Concentric Reducer china mainly has the following features:

1. When the flow rate of the fluid in the pipeline changes, such as increasing or decreasing, and the flow rate requires little change, a variable diameter tube is required.

2. Enter the inlet of the pump, in order to prevent cavitation.

3. At the joints with instruments, such as flowmeters and regulating valves, in order to cooperate with the joints of the instruments, different diameter pipes are also required.
