Experts came for an inspection and said that the height of the vent valve on the underground ethanol storage tank at my facility was insufficient. May I ask, what should the height be? Which standard specifies it? What measures need to be taken if factory pipes are to be welded to the breathing valve? ? ?
I’ve never seen such a rule; is this outlet for direct discharge? I think what he means is that the height of the outlet pipe is not sufficient
I’ve never seen such a requirement for breathing valves
1. The breather valve should be installed at the highest point of the gas space within the storage tank. 2. It should be placed at the highest point of the tank’s floor level. 3. From a safety perspective, the installation location of the breather valve must be appropriate; it should be at least 1.5 times the height of the operators
It is recommended not to weld; it’s sufficient to use an extended sleeve
