Air Leakage "Standard" in Piping Connections and Gaskets
Air Leakage "Standard" in Piping Connections and Gaskets
(OP)
Hello, this is my first question here, a very nice site. Anyways, I was looking to see if there were any "Industry Standards" for expected leakage for something like a 3/4 inch piping connection or from different size gasket or o-ring connections. Such as a 3/4 NPT connection may leak .05 SCFM, a 1 inch o-ring may leak .1 SCFM, a 3 inch rubber gasket would leak .01 SCFM etc. I would not expect it to be much as long as the connections were made properly, but I would guess there would be some leakage if there were a number of valves connected together. Thanks for the Info.

Compare a the service of a line full of compressed air with a line full of propane or worse a line full of H2S

I cannot give you individual allowable leak rates but as far as energy wastage is concerned, a general standard is 7 to 10%. (A web search about leakage of compressed air gives you this data anyhow)
The procedure for checking leakage rate is, check the loading time and unloading times keeping all terminal valves and drain valves closed.
%leak = unload time*100/(load time+unload time)

1. human error, got the right components and good mech's.
2. lack of quality control, in component man'f. and fit-up
3. poor protection of components in handling & storage
4. difficult to access fitting connections
5. lack of education in doing proper fit-up
6. poor eng. specs.
7. improper design of piping or routing.
Close attention to all of the above will help you acheive a zero tolerance standard to leakage.
