There are four primary areas where extruded anodes offer important advantages in cost, performance, and ease of installation:
- Water heaters and water storage tanks, where a small diameter anode simplifies installation.
- Steel located in high resistivity electrolytes, where a small diameter anode gives a desirable current output to anode weight ratio.
- Gas service entrance piping, where a small diameter anode can be driven into the ground to provide convenient and inexpensive protection.
- Prepolarization of structures in seawater, where a small diameter anode gives short-term, high-current output
