16 Cathodic Protection (CP) Available to Purchase

Where carbon and low alloy steel (CLAS) structures are in intimate contact with environmental waters or the ground, it is customary for them to be protected from external corrosion threats at the points of contact by cathodic protection (CP), often in conjunction with a protective coating system. In a similar manner, vessels or tanks used to contain various environments may be protected from internal corrosion by a combination of coatings and CP. This involves making the metal to be protected act as a cathode against an external body which is intentionally made to become anode and corrode in preference to the intended structure.
