Photovoltaic steel support anti-corrosion technology

How a solar energy system can solve the problem of corrosion?

In an effort to solve the serious problem of corrosion of pipelines and underground steel structures, a kind of electrochemical anti-corrosion system based on solar energy has been developed. The system uses photovoltaic technology and forced current cathodic protection technology to effectively protect the metal from corrosion.

Does cathodic protection protect metals from soil corrosion?

In practice, cathodic protection is often used to protect metals from soil corrosion. Metal structures report a certain negative electrical potential, which complicates the thermodynamics of metal oxidation. This significantly reduces (minimizes) the rate of soil corrosion [ 1 ].

Can solar panels protect low-alloy steels?

In the course of experimental work, I found out that to ensure maximum protection of low-alloy steels, cathode current densities of more than 0.387 A/m 2 are required, which are easily achieved using solar modules. This ability is also preserved during the night, currentless period of time.

Can a photovoltaic module be used for cathodic protection?

In this article, the use of a photovoltaic module for cathodic protection (CP) of various metal structures, all pipelines located underground and in water, in particular underground water pipelines, gas and oil products, technological pipelines, was experimentally investigated.

Can a photovoltaic pipeline be connected to a cathodic protection station?

Two samples of the pipeline were connected within 6 months to a cathodic protection station powered by a solar module, and two samples of the pipeline not connected to this system. The schematic diagram of the photovoltaic cathodic protection system is shown in Fig. 2.

Does electrochemical protection reduce the rate of soil corrosion?

This significantly reduces (minimizes) the rate of soil corrosion [ 1 ]. The value of the given potential of electrochemical protection, according to which it is customary to evaluate the work of electrochemical protection (ECP) of the pipeline, is often some average state standard.
