Abstract

A fluid conducting system with cathodic corrosion protection is provided for at least one device that influences and/or acts upon a flow rate, such as a pump and/or valve. The device includes at least one connection device such as a device connection flange. At least one flow rate guiding device such as a pipe includes a connection means such as a pipe connection flange. The system includes annular anodes arranged between the connection devices and connection means, where anodes are electrically connected by electrical conducting lines to a monitoring device. The internal diameter of the anodes is preferably equal to the internal diameter of the flow rate guiding device and/or the inner diameter of the inlet and/or outlet of flow influencing device.
