Electrolytic corrosion of metals
Drinking water, natural gas and domestic wastewater flow through metal structures and are stored in underground tanks, all of which are subject to corrosion.
Any facility with metal components is subject to this phenomenon, which occurs when materials, such as iron and carbon steel, come into contact with an electrolyte, such as soil.
Corrosion is not a phenomenon that can be completely eradicated, but specific measures can be taken as early as the design and construction stage to significantly reduce its effects and ensure the proper functioning, durability, and safety of the systems.
Depending on the technology used, it is possible to implement passive cathodic protection with coatings and inhibitors, or active cathodic protection using sacrificial anodes or impressed current to counteract faults and gaps in the coating caused during installation or by deterioration.
The quality of the cathodic protection service is determined in different ways. There are international standards that require the use of the electric potential between the metal structure and the ground as a criterion for defining its protection.
Pietro Fiorentini started developing and creating cathodic protection monitoring systems in 2016. Service2Business is the software able to interface with devices for the monitoring and remote control of cathodic protection systems.
