I can suggest you to start with the most widespread codes:

- AWWA (American standard) D100-11 Welded carbon steel tanks

- API 650

- SPCC

- ASTM A262

- Michiel P.H.Brongers, “Corrosion Costs and Preventive Strategies in the United States, Appendix G, Hazardous

Materials Storage”, Report by CC Technologies Laboratories, Inc. to Federal Highway Administration (FHWA),

Office of Infrastructure Research and Development, Report FHWA-RD-01-156, September 2001. 

- Code of Federal Regulations, 40 CFP 112, U.S. Government Printing Office, U.S. Environmental Protection

Agency (EPA), Office of Underground Storage Tanks (OUST), Spill Prevention Countermeasure and Control plan

- Steel Tank Institute, STI-P3 (STI-P3 Specification and Manual for External Corrosion Protection of Underground

Steel Storage Tanks), 1999 

-  Underwriters Laboratories Inc., UL 1746 Standard for External Corrosion Protection Systems for Steel

Underground Tanks

@Roberto Nascimbene

thank you for your answer

can you give some more references for tank above the ground,

For steel tank above ground may be considered really important:

- UNI EN 1998-4:2006for silos, tanks and pipelines

- UNI EN 14015:2006 Specification for the design and manifacture of site built, vertical, cylindrical, flat--bottomed, above ground,

steel tanks for the storage of liquids at ambient temperature and above

- Seismic Design of Storage Tanks (December 1986 or November 2009), Recommendations of a Study Group of the New Zealand National

Society for Earthquake Engineering, New Zealand National Society for Earthquake Engineering (M.J.N. Priestley Editor and Chairman).
