INHIBITING OXYGEN CORROSION IN WATER SUPPLY SYSTEMS, PIPING NETWORKS AND WATER-BASED FIRE SPRINKLER SYSTEMS

摘要

A method of inhibiting oxygen in ambient air from entering a water supply system having at least one ingress point at which a fluid can enter the water supply system includes supplying an inert gas to the at least one ingress point of the water supply system. The inert gas enters the water supply system at the at least one ingress point and substantially inhibits ambient air including oxygen from entering the water supply system at the at least one ingress point to substantially inhibit oxygen corrosion in the water supply system. Example pump assemblies for coupling to water supply systems, piping networks, and water- based fire sprinkler systems for inhibiting ambient air, including the oxygen it may contain, from entering the systems are also disclosed.
