Magnesium ribbon anode
Magnesium anodes have the highest protection capability of any
galvanic material. While these anodes are most commonly used in the
cast form, certain structures can be more efficiently protected
through the use of extruded magnesium configurations. Extruded
magnesium anodes have high surface and length ratios in relation to
cross sectional size. This allows these anodes to deliver a higher
current per weight than standard cast magnesium anodes. By
supplying more current, extruded anodes can deliver effective
protection to structures buried in high resistivity soils.
HB offers a full-line of extruded magnesium anodes in both rod and
ribbon forms. Rod anodes are available in an alloy providing
1.4-1.5 volts driving potential (Galvorod). They are furnished with
a variety of connection options and offered in numerous diameters.
Ribbon anodes are manufactured in 3/8" x 3/4" flexible coils which
can be easily shaped for use on a multitude of protection
applications. The ribbon anodes are manufactured in a high
potential alloy (Galvoline) providing 1.6- 1.7 volts driving
potential.
Both rod and ribbon anodes are manufactured with a solid steel core
in the center of the anode. This core distributes current uniformly
through the anode to prevent excessive discharge near the
connection end.
Applied Magnesium research and development in galvanic anodes began
in 1939, and by 1949 Applied Magnesium had introduced extruded
magnesium anodes for use in water heaters. As time went on, Applied
Magnesium learned more about the advantages of anodes with small
diameters and high current output to weight ratios, and identified
several other applications for extruded anodes. Today, Applied
Magnesium offers a complete line of extruded anodes for specialized
cathodic protection applications.
There are four primary areas where extruded anodes offer important
advantages in cost, performance, and ease of installation:
1. Water heaters and water storage tanks, where a small diameter
anode simplifies installation.
2. Steel located in high resistivity electrolytes, where a small
diameter anode gives a desirable current output to anode weight
ratio.
3. Gas service entrance piping, where a small diameter anode can be
driven into the ground to provide convenient and inexpensive
protection.
4. Prepolarization of structures in seawater, where a small
diameter anode gives short-term, high-current output.
