Pressure pipeline safety valves and pressure vessel safety valves
Thread Content
Are the selection requirements for pressure pipeline safety valves and pressure vessel safety valves the same? Is there any difference?
There should be some emphasis. Generally, safety valves are installed directly on pressure pipelines, but in some cases, explosion-proof discs are installed below the safety valves of pressure vessels. As far as I understand - the hazards are different, and the actual considerations should be different.
According to my understanding, there is no difference. The starting point is the same, both for safety, as long as sufficient diarrhea is ensured.
The selection principles of safety valves for pressure pipelines and safety valves for pressure vessels are basically the same, that is, the safety release amount and the discharge amount of the safety valve, the influence of the medium, the influence of operating process conditions, etc. must be considered. For reference!
There is basically no difference in model selection. The main consideration is that the diameter of the safety valve must meet the requirements of the discharge capacity.
There is no difference. The safety valve of some pressure vessels is installed on the outlet pipeline.
The selection method and principle of action are the same.
