When is a pipeline between the outlet and inlet lines of a centrifugal pump used?

When is a pipeline between the outlet and inlet lines of a centrifugal pump used? It’s just a valve that has been added between the outlet and inlet pipelines
The pipeline can be purged by going around the pump.
Can it be used to adjust flow rate or pressure?
It depends on the diameter of the pipeline; smaller ones are used to regulate flow and pressure, while larger ones can be used as cross-connections for pumps
It can also be used as an anti-freezing cross-link in winter to prevent pumps from freezing
Yes, when the demand on the backflow path is low or close to the pump’s minimum flow rate, it is possible to allow some backflow, thereby keeping the pump’s operating conditions within its optimal range
No pictures, no truth; from the description, it seems to be a return pipeline
It’s not the minimum flow line; the minimum flow line is the one that returns to the inlet tank of the pump, while this one goes back to the pump’s inlet

Why is this type of pipeline needed?
