sti-P3 Specification and Manual for External Corrosion Protection of Underground Steel Storage Tanks

The sti-P3® Specification and Manual for External Corrosion Protection of Underground Steel Storage Tanks covers a method of underground exterior corrosion control for steel tanks. The method, termed sti-P3®, combines three basic corrosion control approaches. 

Topics include:

• Compliance
• General Requirements
• Electrical Isolation
• Cathodic Protection
• Tightness Testing
• Coating
• Completion

The sti-P3® system is a practical and economical means of extending the life of underground tanks from a minimum of thirtyyears in corrosive soil conditions to an indefinite term in less severe environments. The design includes a safety factor that will allow for somewhat more than ordinary damage to the coating from shipping and handling and other accidental holidays.
