BK Corrosion's cathodic protection equipment keeps the tanks and piping of your water treatment system from corrosion. We have all the corrosion protection instruments you need.
BK Corrosion supplies cathodic protection equipment to the petrochemical and rubber industries. Our clients include major producers of petrochemicals, including base chemicals, styrene, polystyrene, and polypropylene, in the USA and worldwide. We can help protect your facility pipelines, chillers, and other plant components from corrosion, as well as maximize uptime and efficiency in bringing your petroleum-based products to market.
BK Corrosion provides a comprehensive range of corrosion protection supplies, all within the stringent durability requirements of marine applications. The Omega II rectifiers -- in low-voltage, low-current service -- protect the copper components of reverse osmosis water reclamation pumps on ships or rigs. We also provide all corrosion prevention components, including custom rectifiers, impressed anodes, and galvanic anodes for offshore rigs.
BK Corrosion provides a comprehensive range of cathodic protection and corrosion prevention equipment for companies in the utilities industry. Our cathodic protection instruments, including underground locators, reference electrodes, holiday detectors, and other test equipment, let you verify performance and troubleshoot issues quickly and efficiently. We also offer a complete line of exothermic welding supplies and equipment.
BK Corrosion is the industry leader in providing the aggregate and mining industries with cathodic protection for your facility piping and other underground metallic structures.
As a gas station owner, it’s essential that you take the necessary precautions to prevent underground tank leaks caused by corrosion. We offer all the necessary materials for cathodic protection of your assets.
When you need cathodic protection systems for your anchors and below-grade metallic structures, we have you covered. Galvanic anodes are utilized for the majority of systems installed. These systems are fairly inexpensive to extend the life of your towers and the safety of the surrounding area. Please contact us for any CP needs for your towers.

HVAC Systems
In heating, ventilation, and air conditioning (HVAC) systems, cathodic protection is primarily applied to protect metallic components such as pipelines, condenser coils, chilled water systems, and underground ductwork from corrosion due to exposure to moisture, soil, and as such, CP is a vital method for prolonging the lifespan of HVAC system components. Whether through sacrificial anodes or impressed current systems, CP ensures reliability and efficiency in HVAC infrastructure, reducing maintenance costs and system failures.

Sustainable Energy Systems
Cathodic protection is essential in sustainable energy infrastructure to ensure the durability of wind turbine foundations, solar panel supports and buried transmission components. By mitigating corrosion risks using galvanic anodes or impress current systems, CP contributes to the longevity and reliability of renewable energy assets, reducing maintenance costs and supporting the sustainability goals of the sector.
Zinc anodes are usually applied in low resistivity soils below 1000 ohm-cm and in seawater or produced brines. Zinc is excellent for use as an electrical grounding material. Special 99.99% pure zinc electrodes are used as permanent references under tanks and inside vessels. Zinc has a density of 446 lb/ft3 which is over 4 times the density of magnesium and 2.6 times the density of aluminum. The higher density means that zinc anodes will be much smaller and have a higher resistance to electrolyte, than magnesium or aluminum anodes of the same weight. Zinc has an open circuit potential to a copper/copper sulfate half cell of -1.1 volts, giving it a net driving potential of only 0.25 volts against a steel structure protected to 0.85 volts. Due to the low net driving potential and high density, zinc anodes for earth burial should have a long slender shape. Zinc has a high conversion efficiency of 90% compared to 50% for magnesium; however, it has an electrochemical equivalent of 23.5 pounds per ampere year or 372 ampere hours per pound compared to 17 pounds per ampere year or 500 ampere hours per pound for magnesium. Zinc should not be used when the electrolyte temperature is 135°F or higher. At approximately 140°F, zinc becomes passive and can become cathodic to the structure being protected.

Background: Galvanic Anode Cathodic Protection System
The galvanic system uses the natural difference in potential between metals to cause a direct electrical current from an anode through the soil or water to the structure being protected. BK Corrosion has provided industry with quality cathodic protection equipment for over 65 years.
