Some people say that according to GB50160-1999, it is not necessary to install one; what is the reason for this? Why is it okay not to set it when it is less than 0.03 Mpa?

It’s GB50160, right? A pressure of not more than 0.03 MPa (gauge) classifies it as an external container

Generally, pressure vessels are equipped with them

Refer to the content of GB50160.

It’s a vacuum tower – why is the gauge pressure 0.03 MPa? It should be absolute pressure, right?
