CATHODIC PROTECTION

PERMA-PIPE® Inspection Services provides cathodic protection services that include soil testing, computer generated design/engineering, field installation instruction, system checkout analysis and the availability of cathodic protection materials. CORROSION PREVENTION FOR BURIED, COATED METALS Connecting Wire Cathodic Protection Cathodic protection is a corrosion prevention technology that deters corrosion from coated metallic structures (cathode), buried in moist soil (electrolyte) and redirects it to an expendable material (anode). With a cathodic protection system, a voltage potential force...

Rectifier Systems convert A.C. current to D.C. current and impress a voltage potential force upon the exterior surface of the protected structure through inert anodes (usually carbon or high silicon cast iron). This system differs from the sacrificial anode system only in the manner that current is generated. PERMA-PIPE'’s engineers are certified by the National Association of Corrosion Engineers (NACE) and are experts in the design of cathodic protection systems. We design, manufacture and service quality piping systems worldwide. Sacrificial Anode Types of Cathodic Protection There are two...
