I would like to ask everyone for the definition of a vacuum tube; can anyone provide an authoritative one? Is a pressure lower than atmospheric pressure a vacuum tube? So is the fan inlet duct also considered a vacuum duct? So here’s the question! GB 50316 3.1.2.3 Vacuum pipelines……The design pressure is taken as 0.1 Mpa ； GB 50517 10.1.7 The test pressure for vacuum pipes shall be 0.2 MPa. 10.6.5 For vacuum pipeline systems, after passing the pressure test, a leak test shall be conducted using gas at a pressure of 0.1 MPa. The test shall be carried out in accordance with the requirements of paragraphs 10.6.2 and 10.6.3 of this specification. If we consider even the fan inlet pipeline in this way, it doesn’t seem right, does it? Could some expert give me some guidance?
