What is Zinc Anode?? Where should it be used ?
?
? ??
Q. What do sacrificial anodes do?
?
A.?All metals immersed in an electrolyte (sea water for example) produce an electrical voltage. When two dissimilar metals are in contact (electrically connected) they produce a galvanic cell (like a battery), with the less noble metal (a bronze propeller for example) forming the anode and the more noble metal (stainless steel shaft) forming the cathode.
?
Aluminum anode alloy provides more protection and lasts longer than zinc. It will continue to work in freshwater and is safe for use in salt water. Aluminum is the only anode that is safe for all applications.
?
?
Q. When we we choose to use Zinc anodes ?
?
A.?
?
Exterior of underground or underwater pipe
?
Interior of pipe handling corrosive waters and effluents
?
Lead sheathed electric cable in ducts
?
Other metal-sheathed electric cable in underwater or underground locations
?
Copper concentric neutrals of URD cable
?
Corrosion control and/or grounding of induced AC on underground pipe
?
Annulus space between outer steel casing and inner pipe of deep wells
?
Interior bottoms of oil storage tanks
?
Foamed annulus space of insulated steel pipe underground or underwater
?
Double bottom areas of ship ballast tanks
?
Bottom areas of cargo/ballast tanks of petroleum carriers
