END CUSTOMERS AND STAKEHOLDERS SUPPLIER PORTAL INSTALLERS PRESS SERVICES Cathodic protection The main cause of corrosion of the steel pipes present in the subsoil are the electric currents dispersed in the ground (for example by railway and tram handling systems). To prevent the formation of leaks in the pipes, and consequently the dispersion of gas, it is essential to ensure adequate electrical insulation. Our pipes are therefore protected by a particular coating that does not allow the electric currents present in the ground to affect them. To ensure lasting protection, the laying of the pipes is carried out with extreme care. Further protection systems In addition to the systems described, we use a cathodic protection system. It consists of a series of equipment that gives the pipelines a negative potential with respect to the ground, thus making it impossible to form electrolytic piles on the surface of the pipeline. Maintenance of the cathodic protection system Our specialized technicians check the efficiency of the cathodic protection systems according to a precise maintenance program. They also perform measurements of the potential value of the pipelines in specific points of the plant in order to verify the efficiency of the cathodic protection system as a whole.
