how to reduce corrosion rate of metallic materials?
How cathodic protection can benefit you?
Truly, corrosion is a real scourge in many industries. Corrosion is a gradual process that breaks down the properties of metals. It is a chemical reaction that occurs between metals and their environment. Corrosion is a result of the redox reaction of iron and oxygen in an environment that has water or humidity. Corrosion occurs in structures that are located underground and are exposed to the soil as well as in equipment that is located underwater.
Cathodic protection is an effective technique used to prevent the corrosion and deterioration of metals. It protects industrial equipment and structures such as steel, water pipelines, storage tanks, oil platforms, ships...
How does cathodic protection work?
The harmful process of corrosion can be effectively prevented and managed through cathodic protection. Cathodic protection is adaptable and can be adjusted through the asset life to suit the changing environment and corrosion conditions.
The cathodic protection process involves the conversion of anodic sites on the metal surface into cathodic sites; this process is known as a cathodic electrochemical reaction.
Cathodic protection can be used on various types of metal structures in various environments. It is one of the few methods of corrosion control that can competently protect a submerged metal surface. In order for the cathodic protection process to be effective, it is important to ensure that reliable cathodic protection adapted to the required system is acquired.
Remote monitoring of cathodic protection
The phenomenon of "stray currents" accelerates and aggravates the deterioration of metal structures which increases the risk of accidents and unplanned shutdowns. In addition, these incidents impact on your profitability as well as being a threat to your staff and environment. Cathodic protection monitoring is a corrosion prevention method used on buried pipelines. It involves the use of equipment, sensors and alarms to detect changes in pipeline chemical composition or leaks by making the pipeline a cathode of an electrochemical cell.
2 Wize Alliance members work on cathodic protection monitoring solutions
SIS Smart Solutions is a Wize Alliance member since 2020 and is going to market a stand-alone and efficient solution in Q2 2022 to reduce gas operating and maintenance costs. Deployed at the heart of the infrastructure, the equipment collects and transmits data that will allow to regulate the extraction and drainage stations according to customers needs and thus to extend the life of their infrastructure.
TAIGA PC allows to adjust the filling stations, ensure the efficiency of the drainage station and receive alarms in case of malfunction.
The ECHO system by Jacquet Dechaume and Cedarnet is designed and adapted to the specific needs of monitoring and management of cathodic protection. It is a Wize Alliance member since 2020. The ECHO system is operational since 2021 and is already selected by major energy network operators and deployed.
The ECHO system is a complete digital chain of remote monitoring, supervision and remote-control capability. ECHO system optimizes operations and reduces maintenance costs.The system is an up-to-date electronic for measuring voltages and currents in a harsh environment for all cathodic equipment. Communications and data exchange comply with security and confidentiality requirements. The installation of the ECHO system is easy, and configurable to stick to the organization of the operator, with the choice of its levels of alarms, and the possibilities of remote control.
