Standard for Dual Wall Underground Steel Storage Tanks (F841)
All Products
The Standard for Dual Wall Underground Steel Storage Tanks (F841) addresses underground double containment (atmospheric-type) vessels with built-in interstitial monitoring capability for the purpose of giving advance notice to avoid environmental contamination.
The primary intent of this standard is to address the petroleum storage segment, although other products, including hazardous chemicals, can be covered by this standard. It should be noted that certain products and chemicals will require 360° double wall containment.
Topics include:
- Design Criteria
- Capacities, Dimensions, and Materials
- Seams and Joints
- Lug Lifts
- Monitor Well
- Monitoring Interstitial Space
- Striker Plates
- Corrosion Protection
- Testing
This standard is based on the application of sound engineering principles and the combined experience of the STI/SPFA membership. It represents a composite of data from users, manufacturers, regulatory authorities and consultants.
