Can a pipe flame arrester be connected directly to a valve?
Thread Content
Request for help: The oil and vapor recovery pipeline at the top of the tank is connected to the main oil and vapor recovery pipeline; it is necessary to install pipe flame arresters and isolation valves. Can the pipe flame arresters and isolation valves be connected directly to each other (flange to flange)? If the two are connected, must there be a short section in between? Which specification or standard contains such a provision?
It should be possible, but it is necessary to cut out and clean it from time to time. There should be valves at both ends of the flame arrester, and one of those ends should have a short section along with a vent.
Thank you! However, this is a pipe flame arrester, not a flame arrester for venting.
I'm talking about pressure relief and venting after cutting but before releasing the flange.
It is also necessary to consider whether flame arresters and valves can be installed
To connect the pipe flame arrester to the valve body, a short section is required!
As long as it’s easy to bolt on, that’s fine. . . . .
The valve shouldn’t be used directly; what is the function of a flame arrester?
It can be connected; they do it that way on site
