What is the purpose of cathodic protection cable (HMWPE Wire)?
Cathodic protection stops metal from corroding by controlling the chemical reactions that cause it. This technique is used to protect pipelines, tanks, offshore structures and other metallic components in corrosive environments.
Cathodic protection uses a direct current to make the metal structure the cathode in an electrochemical cell. This stops the metal from corroding and makes it last longer.
There are two main ways to protect metal with cathodic protection: galvanic and impressed current. Galvanic protection uses sacrificial anodes made of a more reactive metal, such as zinc or magnesium, to protect the structure. Impressed current protection uses an external power source to supply the necessary current to the structure, typically through inert anodes.
HMWPE Wire stops metal structures from rusting and keeps them safe and reliable.
