  • Patent number: 10017864
    Abstract: An automated tank Cathodic/Corrosion Protection (CCP) monitoring system includes a mobile CCP data collection device. The data collection device can be moved horizontally to different locations in the tank. A reference electrode and corrosion coupon are lowered from the data collection device to desired depths within a liquid medium in the tank to collect data. The data collection device is connected to a programmable, external control unit enabling a operator to program a data collection schedule, the horizontal and vertical distance between readings, interruption of the system if the system is designed in a way to handle interruption, and has the ability to transmit the data remotely to a control center. These capabilities enable automated, remote monitoring of the CCP system, eliminate the safety concerns associated with sending technicians onto tank roofs, and give a more accurate and complete representation of the CCP system functionality and level of protection achieved.

  • Patent number: 9909220
    Abstract: In a method of corrosion protection of rebar in concrete the sacrificial anode is held in place by wrapping a first wire around a first rebar portion and a second wire at second rebar portion and twisting together the first and second free ends to tension the wrappings. This can be used either on two separate rebars which are parallel or at right angles or can be used at longitudinally spaced positions on a single rebar where the rebar roughening prevents the two wrappings from sliding as the wires are tensioned by the twisting. In many cases a covering material such as a porous mortar is cast onto the outer surface of the anode and in this case the mortar and the wire are located such that the wire exits from the sacrificial anode at a position separate from the layer of covering material.
