Impressed Current Cathodic Protection System Evaluation Checklist Mobile App

Cathodic protection is used for controlling metallic corrosion by making the metal surface a cathode of an electrochemical cell. Anodes and cathodes are electrodes - the anode is the electrode that positive current flows into, and the cathode is the electrode that it flows from. Anodes experience oxidation and cathodes experience reduction during the flow of electricity - these characteristics are the basis for cathodic protection systems. This app covers testing of these impressed current cathodic protection systems specifically outlining a moving ground continuity test and a point-to-point continuity test. The app notes the owner of equipment and systems being tested, the tester's information, the reason the evaluation is being performed, whether the test was passed or failed, actions required as a result of the testing, and more. This app is designed for protection systems related to underground storage tanks such as steel tanks for holding liquid gas, leachate water, or other liquids. The process outlined for testing involves the use of a reference electrode, connecting the reference electrode with lead wires to a voltmeter, and obtaining readings. The guidelines for the app help to minimize the chance of stray currents impacting results, ensure that the test areas have a proper level of moisture to minimize unnecessary resistivity. The app also provides useful tips for each testing method involved in this app. Ultimately, proper evaluation and testing of corrosion prevention systems can ensure that the corrosion process is halted when possible and that submerged tanks are kept in good working order.

How It Works
I’m not a tech guy and I was able to pick this thing up in probably an hour, and actually start to build apps. I’ve done them over lunch when I’ve gotten frustrated with a process that didn’t exist in our company. So for non tech people who’ve got a problem, the support here is awesome and I’d recommend it to anybody, not just in our industry.
