Why are flame arresters on storage tanks installed below the vent valve, rather than above it?
I don’t know if there are any rules. However, from a structural perspective, the load-bearing capacity of the breather valve itself and the design of the breathing opening make it difficult to install something behind the breather valve
If it is in contact with the process upstream of the breather valve, it is prone to clogging.
Ugh, a flame arrester is installed on the storage tank to prevent backflow of gas when the breathing valve releases gas – so what’s the point of installing it on the breathing valve itself? If you have any more questions, contact me at 13912008028; the same number is used for WeChat as well
The breathing system of oil tanks usually consists of a breathing pipe, a breathing valve, and a flame arrester; the specific arrangement varies depending on the type of oil tank. Mechanical breathing valves are generally installed above the flame arrester, while pipeline-type breathing valves are usually placed below it, although the model of the flame arrester may differ in such cases. Both the common crude oil storage tanks and light oil storage tanks on site are equipped with mechanical breather valves.
