Cathodic protection

Cathodic protection is a technique of prevention against electrochemical corrosion applied to metallic structures that are in contact with electric conductivity environments. It consists in circulating continuous current between an electrode, called anode, and the surface of the structure to be protected, called cathode. This current lowers the electrical potential on the metallic surface, up to excluding the corrosive phenomenon. The cathodic protection technique officially appeared in England in 1824, and it was affirmed in America a century later, and throughout the world beginning from 1960 and 1970. Cathodic protection was first applied in Italy to protect lead conduits of telephone cables around 1930, and later on to protect oil pipelines, gas pipelines, aqueducts and structures at risk to corrosion.

Passive Cathodic protection

An electrochemical way of protection against corrosion is the one that uses "sacrificial anodes" (cathodic protection), that is of bodies...

Telecontrol

SAIM has managed the telecontrol of cathodic protection plants of entire oil pipelines for years.
The daily service offered reduces the number of staff on the part of the customer, reduces inefficiency and makes it possible to be quickly informed of any technical fault or anomalous situation.
With the new technologies available on the market, SAIM is able to monitor besides cathodic protection plants, also railroad crossings, critical and significant points.
