Selection of pressure for ammonia leakage test
Thread Content
In HG20583, Appendix A, section A.2.3, the pressure for the ammonia leakage test is set at 1.05 times the design pressure. In the design process, we can use the design pressure as the test pressure (it seems that this is specified in some regulations or books). Could someone please tell me where this requirement can be found? Thank you
Is the pressure of ammonia leakage related to the design pressure? Isn’t the pressure for ammonia leakage and the operating procedure specified in the appendix of HG20584? Generally, a ammonia leakage pressure of 1.0 MPa is sufficient!
Ammonia leakage detection is also a method for conducting airtightness tests. According to Article 101, \"the test pressure for the airtightness of pressure vessels is the design pressure of those vessels.\" Generally, the design pressure is used in the ammonia-air method. Appendix A of HG20584 specifies the scope of application and detailed procedures for these three ammonia leakage detection methods. This post was last edited by JHJZYQ on 2008-3-17 at 10:07
I agree with the view above: if ammonia leakage is allowed to reach 1.05 times the design pressure, it becomes quite dangerous, and systems with higher pressures cannot pass the tests
Got it, thanks. I’ll try my best to understand the specifications:lol
