TechData Sheet, June 1995. Cathodic Protection System Design III - Sacrificial Anode System Design Principles for Underground Structures
Abstract
The most common application of cathodic protection is controlling corrosion on buried structures, such as pipelines and storage tanks. The design of a cathodic protection system for such structures is described in detail in MIL-HDBK 1004/10. For underground structures, both impressed current and sacrificial anode cathodic protection systems are feasible and the most appropriate system is chosen based on life cycle cost for the system. Therefore, in order to select the most cost effective system, it is common to make a preliminary design of both types of systems for a specific application so that the life cycle costs can be estimated. The design of both types of system requires a pre-design field survey as described in Techdata Sheet 2020-SHR. In this survey, information required to establish the amount of current required for protecting the structure is developed. This current requirement is the same whether the structure is protected using a sacrificial or impressed current system and is the basis for the remainder of the system design.
