Cathodic Protection-Corrosion resistance and cathodic protection addresses new challenges

Cathodic protection is essential in protecting metal applications in a range of conditions that can lead to corrosion activity. The metal anode used in the process shields the metal from potential corrosion. This particular protective measure is particularly beneficial in environments where pieces are submerged.

What is cathodic protection?

Cathodic protection consists of using a metal anode to eliminate or control corrosion. Cathodic protection involves the use of a sacrificial metal layer or barrier that is exposed to the corrosive environment. In acting as a barrier, the other metal is protected. The goal is to protect the various applications from rust accumulation. The actual anode is dissolved when the application is submerged to eliminate corrosion from happening.

Common scenarios where they are used

Any steel application that is ever submerged in water are treated using this process. Cathodic protection can be used in pipelines, piles, boat hulls, storage tanks, water heaters and oil well. Coatings like zinc are used to prevent the rust activities. Metallic structures can be protected with cathodic protection. In some cases, the protective method can be used in conjunction with a DC electrical power source for additional activity.

Other applications where cathodic protection is used

• Wind turbines
• Generators
• Pontoons
• Dock gates
• Water tanks

As an alternative to other corrosion control methods

Cathodic protection is considered a good alternative to protective coatings. For buried applications and submersion in waterfront structures, the cathodic protection method is the preferred means of controlling corrosion. This is because compliance and regulatory requirements are more easily met using cathodic protection. There are a number of safety and environmental consequences for application failure. Federal, state and government entities continually increase their requirements for general storage and use of metal applications to prevent disastrous or dangerous conditions from happening. Cathodic protection addresses the need for improved corrosion resistance to meet these new challenges.

Using Capac corrosion systems

Capac corrosion protection systems provide an automatic cathodic protection for boats. The boats can be submerged without experiencing corrosion and rust. An automated controller, a control electrode, surface anode and a meter are used as a part of the system. The protective current is released from the anode and flows into the water to submerged metal parts to reduce and eliminate corrosion. Anode currents are increased automatically in the system whenever the electrode potential drops beneath the preset control value.

Advantages of using such a system

The user-friendly systems put protection in complete control of the operator. Overhead associated with labor are reduced because of the automation features and reduced reliance on manual operation. Easier maintenance resulting from cathodic protection reduces cost of ownerhip. Oscillation and overprotection are other problems managed with the system.

Cathode protection is necessary for a variety of applications. Since required in a range of applications, Capac corrosion protection systems make it easier to adhere to compliance standards. Capac systems provide a reduced maintenance, less labor intensive way to prevent corrosion from causing damage to applications vulnerable to the problem.
