What must be ensured when installing cathodic protection anodes?

When installing cathodic protection anodes, it is critical to ensure that the location and depth adhere to design specifications. This is essential because proper placement is necessary for the anodes to effectively mitigate corrosion on the targeted structures, such as underground storage tanks or pipelines. The depth and location are determined based on various factors including soil resistivity, corrosion rates, and the overall design of the cathodic protection system.

Following these specifications ensures that the current output from the anodes can effectively reach the metal structure being protected, optimizing the performance of the system. If anodes are placed incorrectly, they may not provide adequate protection, leading to potential corrosion issues and the associated costs of repairs or replacements. Thus, adherence to design specifications directly influences the effectiveness and longevity of the corrosion protection provided by cathodic anodes.
