摘要： A corrosion monitoring device for pipe systems according to one aspect of the present disclosure includes a pipe having a first pipe portion and a second pipe portion. The first pipe portion includes a wall having a first wall thickness, and the second pipe portion includes a wall having a second wall thickness that is greater than the first wall thickness. The corrosion monitoring device further includes a structure coupled to the pipe and defining a sealed chamber between the structure and at least the first pipe portion, and a sensor for sensing a pressure in the sealed chamber or for sensing a liquid in the sealed chamber. Example corrosion monitoring devices and methods for monitoring corrosion in pipe systems are also disclosed.

摘要： An air maintenance device (AMD) for fire protection system includes a gas inlet configured to couple with a source of compressed gas; a gas outlet configured to couple with a pipe network of the fire protection system; a first sensor configured to sense a system parameter of the pipe network of the fire protection system and to produce a first output corresponding to the system parameter; a first gas flow valve in fluid communication with and between the inlet and the outlet; and a first control circuit in communication with the sensor and with the first gas flow valve. The first gas flow valve is electrically controlled and configured to control a flow of gas from the source of compressed gas into the pipe network. The control circuit is configured to receive the first output from the sensor and output a control signal that is a function of the system parameter to the first gas flow valve. Other example AMDs, systems including AMDs, methods of installing AMDs, and methods of suppling gas to a pipe network using an AMD are also disclosed.

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.

摘要： A fire protection sprinkler system includes a water source, a sprinkler, a piping network interconnecting the water source and the sprinkler, and an automatic gas vent coupled to the piping network and configured to discharge gas from the system. The automatic gas vent includes a sensor configured to sense a presence or absence of a liquid and an electrically operated valve. The automatic gas vent is configured to open the electrically operated valve in response to the sensor sensing the absence of a liquid and close the electrically operated valve in response to the sensor sensing the presence of a liquid. Automatic gas vent assemblies and methods of venting and discharging gas from fire protection sprinkler systems are also disclosed.
