What is the difference between gas fire fighting with pipe network and gas fire fighting without pipe network? Under what circumstances is it applicable?

If there is a pipe network, it can be used in two or more protected areas, which can save fire extinguishing agent and gas cylinders, but a separate room should be set up to put fire extinguishing agent and store gas cylinders. Without a pipe network, the fire extinguishing agent cylinders are directly placed in the protected area, and the fire extinguishing agent is directly sprayed to the protected area through the nozzle after coming out of the bottle head valve. In addition, because the equipment without pipe network system is directly set in the protected area, the storage pressure is lower than that with pipe network system.
