Deflagration vent
(OP)
I need to design / fabricate or preferably purchase some deflagrationa vents. I downloaded NFPA 68 and am absorbing it. Please are there any suppliers or typical designs out there?

Thanks for the info. Perhaps a little clarification is in order. I am designing fixed and floating covers for an API oil/water separator. It is an outdoor concrete basin in which oily water is held. The fixed covers rest 2 feet or so above the liquid level. The largest is about 10 feet by 70 feet. You used an internal volume to size the vents, NFPA uses ineternal surface area. Comment?

By the way... regarding the issue of sizing based upon volume versus sizing based upon internal surface area... the NFPA 68 guidance distinguishes between weak enclosures and strong enclosures. Vent sizing methodologies are based upon internal surface area for weak enclosures, and internal volume for strong enclosures.
The type of flammable or combustible material makes a big difference in the required vent area also.
NFPA 68 takes some experience to apply properly... find a reputable vendor.

I have encountered similar results using NFPA for deflagration venting. Sometimes the vent size exceeds the diameter of the tank!!!
