Design and Development of Cathodic Protection and Atmospheric Corrosion Sensor on Metal Pipelines of Liquigaz LPG Jetty Area

By using the metal surface as the cathode of an electrochemical cell, cathodic protection is a technique used to control the corrosion of a metal surface. A straightforward protective technique links the metal that needs to be shielded to a "sacrificial metal" that corrodes more readily to serve as the anode. While atmospheric corrosion monitoring aids in identifying and reducing corrosion risks brought on by external conditions, it is also essential for preventing corrosion on submerged or buried pipes. The main objective of this research is to offer different approaches to stop the metal pipelines from corroding. The researchers conducted a thorough assessment of the environmental conditions, pipeline materials, and corrosion challenges of the Liquigaz LPG jetty area in order to determine the specific requirements for the cathodic protection and atmospheric corrosion sensor system. They also demonstrated alternative methods of preventing the frequent coating or painting of the metal pipelines for the corroded part. The researchers utilized the requirements analysis to construct the atmospheric corrosion sensor, which allows us to create a cathodic protection system that is suitable for the temperature, humidity, and impurity levels that the metal pipelines are subjected to. When in the protective cathode the researchers created sensors that can measure critical characteristics, such the galvanic cell--an electrochemical cell that transforms chemical process free energy into electrical energy--that determines how efficient cathodic protection is. The study presents the monitoring of corrosion in metal pipes by creating and executing a cathodic protection system and an atmospheric corrosion sensor. Through the analysis of environmental conditions and the application of electrochemical principles, These solutions provide efficient and long-lasting protection against corrosion. This results in reduced maintenance costs and extended lifespan of metal pipelines in corrosive surroundings.
