API standard 650 welded storage tanks bolting

According to API standard 650, the stairs used for API 650 petroleum storage tanks or thermal insulation tanks should be double longitudinal beams supported by a minimum of ribs. If the gap between the API standard 650 welded storage tanks tank shell and the stringer of the API 650 petroleum storage tank exceeds 200mm, handrails should be provided on both sides of the stairs. Unless otherwise specified, according to API standard 650 welded storage tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.

The main content of the inspection of the safety management of metal atmospheric API standard 650 welded storage tanks is whether the filed data of the storage tanks are complete; whether the operators have received safety management training; whether the problems detected in the past have been resolved. The main inspection content of the tank body of the metal atmospheric pressure storage tank is whether the tank top, tank wall, and bottom plate of the storage tank are deformed, dented, seepage and perforation, etc.; whether the API standard 650 welded storage tanks accessories are complete and whether there are any abnormalities; No sinking, tilting, etc.

Investigation of Subgrade
On actual steel storage tank sites to be used, test borings or test pits, or both, may be made at the direction of a competent engineer who will specify the number and location. They need not be equally spaced but should be laid out to uncover possible weak spots.
In general, test loadings of subgrade at the bottom of test pits need be resorted to only when such heavy loading as may be imposed by footings for major column supports for spheres or similarly elevated API 620 low-pressure tanks is specified. Results may be deceptive if average load-bearing capacity over a considerable area is wanted. All field data shall be recorded with maps, and copies shall be supplied to all engineers concerned with design, erection, and later operation.
