Zinc Rod Applications
Zinc metal is widely applied to shipping, steel pile, floating dock, bridge, ballast tank, submarine pipeline, sluice, underwater wire rope etc. The offshore platform has great use of Zinc metal, such as port engineering and marine engineering facilities, underground cables, underground oil and gas pipelines, oil well casing, tank wall, bridge foundation, reaction kettle, concrete foundation, heat exchanger, complex water gas, box type cooler, water pipe inner wall, pump, compressor, chemical tower, container, storage tank, etc.
Zinc Rod Packaging
Our product is clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
Zinc Rod FAQs
Q1. How do zinc rods work in cathodic protection?
Zinc rods act as sacrificial anodes, meaning they corrode instead of the protected metal structure. When connected electrically to the structure, zinc rods provide electrons to the metal, reducing its corrosion rate by shifting the electrochemical potential to a more negative value.
Q2. What types of zinc rods are available?
Zinc rods come in various sizes and purities. The standard purity for cathodic protection applications is usually 99.99% zinc. The rods can vary in diameter and length, depending on the specific requirements of the application.
Q3. How are zinc rods installed for cathodic protection?
Zinc rods are typically installed by either welding or bolting them to the metal structure that requires protection. They are then connected electrically to the structure, ensuring a good conductive path. The rods are often placed in locations where they can be easily inspected and replaced if necessary.
