NACE Standard RP0196-2004
Galvanic Anode Cathodic Protection of Internal Submerged Surfaces of Steel Water Storage Tanks
The purpose of this standard recommended practice is to present the procedures and practices used in providing galvanic anode cathodic protection (CP) to the normally submerged steel surfaces inside water storage tanks. This standard provides owners, engineers, and contractors with specific guidelines for the design and installation of these CP systems; methods for determining the effectiveness of these systems; and recommendations for the operation and maintenance of these systems. This standard is applicable to water storage tanks of various sizes used in municipal water supply and fire protection, including elevated tanks and flat-bottom tanks at ground level. Although the general principles outlined in this standard are applicable to all such tanks, the galvanic anode CP system described in this standard may not be practical for relatively large tanks.
