Question: How to choose the diameter of a safety valve or vent?
Thread Content
Some reaction equipment generates large amounts of high-pressure gas in a short period of time. To allow for the timely expulsion of this gas and to prevent static electricity from being generated due to high flow rates, how should the diameter of the safety valve and the diameter of the vent be selected? Are there any **standards to refer to in this regard?
Generally, these standards are mainly referred to: the \"Regulations on Safety Inspection of Pressure Vessels\", GB150 for steel pressure vessels, and HG/T 20570.2-95 on the installation and selection of safety valves. The latter standard provides very detailed information. There is plenty of material on this topic available on forums, so be sure to search for it
