Magnesium Anodes Cathodic Protection magnesium ribbon anode

Product Description

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.
