HIGH NITROGEN AND OTHER INERT GAS ANTI-CORROSION PROTECTION IN WET PIPE FIRE PROTECTION SYSTEM

摘要

A wet pipe fire protection sprinkler system and method of operating a wet pipe fire sprinkler system includes providing a sprinkler system having a pipe network, a source of water for the pipe network, at least one sprinkler head connected with the pipe network and a drain valve for draining the pipe network. An inert gas source, such as a nitrogen gas source, is connected with the pipe network. Inert gas is supplied from the inert gas source to the pipe network. Water is supplied to the pipe network thereby substantially filling the pipe network with water and compressing the inert gas in the pipe network.
