Electric valve for fire-fighting dual-purpose gun in tank area
Thread Content
For the fire-fighting dual-purpose gun in the crude oil tank farm, is that foam pipeline a pipe for pre-mixed foam or a pipe for pure foam? Is it necessary to install a bypass for the fire-water pipeline?
It’s a fire-fighting and foam-suppression gun for crude oil storage areas; that foam pipeline is the one used for delivering the pre-prepared foam mixture； Generally, there is a cross-line valve for the fire water pipes outside the tank farm perimeter wall. Our company does not use foam concentrate; instead, it is mixed with fire water before being used. Personal opinion.
