What is the purpose of designing a branch pipe with a blind flange at the outlet of a centrifugal pump?

As shown in the figure: What is the purpose of adding a blind flange to this small branch pipe?
This small branch pipe with a blind flange is used for venting and draining air and liquid at the outlet of the centrifugal pump. When a centrifugal pump is started, gas may accumulate in the pipes or the liquid may fail to flow. By opening the blind flange, the accumulated gas can be expelled or the liquid can be drained, ensuring the proper operation of the pump. At the same time, the length and diameter of this branch pipe also need to be designed based on specific usage conditions and requirements. .
In my opinion, pressure gauges and exhaust systems do not require such thick pipes; if valves are needed for temporary liquid discharge or similar purposes, the designer may include them as a backup option.
Agreed; it’s impossible to remove 50 blind flanges for exhaust
Is it possible that it’s equipped with a safety valve?
