Steam separator tank?
Thread Content
Does a steam separation tank fall under pressure vessels? Is it still necessary to add a safety valve?
Whether it is a pressure vessel depends on the operating pressure and volume, and has nothing to do with its intended use
After calculation, it is classified as a type of pressure vessel, but no safety valve is installed on site? ?
There is no safety valve installed on site, so you suspect it doesn’t qualify as a pressure vessel? Do you think your site should be built in accordance with the standards, or should the standards be formulated based on the actual conditions of your site? Regarding the installation of safety valves, you can watch Professor Gao Da’s lecture; it mentions that if a safety valve is installed at the high-pressure end of the system, it may not be necessary to install one here
It’s of course a pressure vessel, and a safety valve is also necessary
Did they forget to include a safety valve in the design?
If the design pressure is higher than the pressure at the steam source, a safety valve is not required.
