Which code is primarily associated with corrosion control of underground storage tank systems by cathodic protection?

The code primarily associated with corrosion control of underground storage tank systems through cathodic protection is RP0285. This document, developed by NACE International, provides recommended practices for the design, installation, operation, and maintenance of cathodic protection systems specific to underground storage tanks. It outlines criteria for evaluating the effectiveness of cathodic protection and ensures that these systems adequately protect against corrosion attacks.

Understanding the significance of cathodic protection for underground storage tanks is crucial, as these tanks are often subjected to aggressive environmental conditions, including soil and moisture, which can lead to corrosion. RP0285 serves as a comprehensive guide to ensure that the protective measures applied effectively mitigate corrosion risks and prolong the lifespan of the tank systems.

The other codes mentioned have different focuses; for example, SP0169 deals with the control of external corrosion on metallic structures, while SP0176 addresses the integrity of buried or submerged metallic structures. SP0290 provides guidelines for cathodic protection in various applications but is not specifically tailored to underground storage tanks like RP0285.
