Description / Abstract:

This standard describes automatically controlled, impressed-current cathodic protection systems intended to minimize corrosion of interior submerged surfaces of steel water storage tanks and 30-in. (750-mm) diameter and larger wet risers of elevated tanks.

This standard does not describe sacrificial (galvanic) anode-type cathodic protection systems or manually controlled, impressed-current systems. Sec.

Purpose

The purpose of this standard is to provide the minimum requirements for automatically controlled, impressed-current cathodic protection for the interior submerged surfaces of steel water storage tanks, including design, system components, quality of work, and installation. Refer to appendix B for operation, monitoring, and maintenance considerations.
