Applications

1. When there is a change in the flow rate of the fluid in the pipeline, such as an increase or decrease, and the flow velocity requirement does not change significantly, a reducer should be used.

2. To prevent cavitation at the inlet of the pump, a reducing pipe is required.

3. In order to match with the joints of instruments such as flow meters and regulating valves, reducing pipes are also required.
