Doesn't exist. NACE will have some guidelines, but it is too general a problem with too simple a set of answers for a 'One Size Fits all Tanks" procedure.
You can get a 'canned' spec from any of the major mfr's of industrial paint. You tell them tank temperature range, tank's exposure; latitude, shading if any, vapors in the area, cooling tower spindrift, sea breeze, etc. Then tell them your expectations 5 years, 10, 20-years. They will give you the coating 'system'; metal prep [blast profile], temperature and humidity limitations during application, and the layers and minimum thicknesses. For a seashore, or 10 to 20-year job, anticipate a primer layer, an intercoat, and a topcoat [different stuff than the intercoat]. All with minimum and maximum times between applying layers.
