ABSTRACT:
A water aerosol or fog-generating system comprises a pipe having a plurality of atomizing nozzles threaded to the walls thereof. The pipe has thin walls made from an alloy, preferably stainless steel, with nozzles affixed at various points along the piping. A plurality of pilot holes are provided at each nozzle location and the edges of each pilot hole are deformed inwardly by a punch so that more surface area is provided for threading the walls of the pilot hole. Preferably, the pilot hole has been reamed after punching and before the threads are made. An atomizing nozzle is mated with the threads on the punched and reamed hole. Seals are to be placed between the nozzle and the exterior piping surfaces.
