Hi my friends
Do you know of any specifications or standards regarding the minimum pipe length for process vents (not Hydraulic Vent)?

None I've ever heard of, but you need to vent hazardous gases to a "safe location ".

Now what that is can be very variable.

Your not giving us much information here.
