As shown in the diagram, what are the many small holes next to the flange on the fire protection pipe for? Please, experts, tell me. Thank you
It’s for spraying, right? Unless it’s for draining liquid?
This is a foam generator; the small holes are for air intake, while the pipe carries the foam – it’s a foam fire extinguishing system used on the surface of liquids.
Those small holes are used to draw in air, as fire foam needs air to be mixed with in order to form foam.
