Cathode protection system1/30/2024 The impressed current system uses an outside source of electricity from a DC power supply, powered by solar, wind or the power company. Any material on the list will protect any material listed below it. Also listed is the voltage or potential of the materials in seawater in relation to hydrogen. The electromotive series (Table 1) lists several materials from the most anodic, or most active, at the top of the list to the most cathodic, or least active, at the bottom of the list. Then they must be replaced for protection to continue. The anodes must be large enough to provide protection for a reasonable length of time before they are dissipated. These anodes are designed to corrode and “sacrifice” themselves to protect the pipe, tank, etc. Magnesium, zinc or aluminum are typical sacrificial anode materials. The galvanic system uses a sacrificial anode of a material having a higher potential on the electromotive series than the material to be protected (Fig. They are available in a single unit capacity of 75 to 225 amperes, as required for various installations.There are two general methods of cathodic protection, ICCP anodes are manufactured in Linear Loop, Elliptical and Circular designs with insulating holders. Mixed Metal Oxide anodes of are used exclusively for ICCP systems. The computer controller (shown below is more accurate and provides central control, monitoring, data storage and hard printout. We also offer optional digital control, state-of-the-art technology with every system. An over- and under-potential alarm is provided with the system package. Anode current automatically increases when the electrode potential falls below the designated control value. Cell/Electrodes constructed of Zinc are used exclusively with the ICCP system.Įach standard ICCP system utilizes a solid-state controller which monitors and controls the protection as measured by the Zinc Referance electrode. This cell/electrode is freely corroding and it becomes the starting point - or reference - in eliminating corrosion. The third cell/electrode is insulated and does not receive any anode current. This control is obtained by inserting a third electrode between the anode and the cathode. ICCP systems are controlled to assure optimum protection. Refer to information below for detailed specifications Simple installation to all kinds of new building as well as retrofitting ships.Data communication and alarm signal can be connected to ship’s AMS.Very convenient operation on easy and sophisticated controller.Data download is applicable through USB memory.Our ICCP System is designed for our world wide clients with the following features. Only one installation required for the life of the vessel or structureĭesigned to provide a 20 plus year service life.Optimum documented corrosion protection at minimum overall cost. Automatic control equipment ensures reliable, simple operation.Anodes, reference cells and automatic control systems maintain just the right amount of protection for underwater hulls and fittings, unlike standard zinc anodes, which can’t adjust to changes in salinity or compensate for extreme paint loss.Anodes are light, sturdy and compact for easy shipping, storage and installation.Increased life of rudders, shafts, struts and propellers as well as any other underwater parts affected by electrolysis.
