Construction of API Std 650 SUG I tanks
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 Std 650 SUG I 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 Std 650 SUG I tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.
The Field-assembled storage tanks manufacturer shall determine that each magnetic-particle examiner meets the following requirements:a)The examiner has vision with correction, if necessary, to be able to read a Jaeger-Type No. 2 Standard Chart at a distance of not less than 12 in. and is capable of distinguishing and differentiating contrast between colors used. These requirements shall be checked annually.b)The examiner is competent in the techniques of the magnetic-particle examination method for which the API Std 650 SUG I tanks examiner is certified, including making the examinations and interpreting and evaluating the results; however, where the examination method consists of more than one operation, the examiner may be certified as being qualified only for one or more of these operations.
The water dissolved in the oil will be separated out from the oil stored in the API Std 650 SUG I tanks for a long time, and the acidic water layer will appear at the bottom of the API Std 650 SUG I tanks for a long time, which will accelerate the corrosion of the API Std 650 SUG I tanks and cause the wall thinning and even leakage. With the increase of service life, the API Std 650 SUG I tanks must be inspected and cleaned regularly to check the hidden danger.
