"Galvotec Anodes - Protecting the World Against Corrosion"
Galvotec's magnesium anodes are produced in a variety of shapes and sizes
for use in seawater, brackish water, and fresh water cathodic protection
Our experience in producing galvanic anodes assures that you will receive
top quality anodes that will effectively inhibit corrosion when used in a properly
designed and maintained cathodic protection system.
Galvotec's magnesium anodes conform in composition to the
requirements of U.S. Government Specification MIL-A-21412A (Ships). This
6% aluminum, 3% zinc alloy (AZ-63) usually provides the best combination of
economy and operating characteristics in seawater or brackish water.
The current efficiency of Galvotec's magnesium anodes is nominally 55% in seawater
and the current capacity is about 550 amp-hr/lb. The open circuit potential of the
magnesium alloy used is nominally -1.55 volts to a copper/copper sulfate half cell in
seawater; the driving voltage to galvanized steel is about 0.70 volts, providing a
relatively high current output per anode. Both hull and condenser anodes are available
with a plastisol (polyvinyl chloride) coating which serves as an excellent current barrier shield.
Magnesium anodes are effective and economical corrosion fighters
that for over 25 years have been protecting a variety of steel structures in salt,
brackish and fresh water, including:
- Hulls of ships, barges, tugs and boats
- Ballast tanks of ore carriers and similar vessels
- Water storage tanks
- Piers and pilings
- Heat exchangers
- Travelling screens
