6m diameter API 650 duplex stainless steel 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 650 duplex stainless steel 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 650 duplex stainless steel 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 650 duplex stainless steel 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 main advantages of the external floating roof API 650 duplex stainless steel tanks are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API 650 duplex stainless steel tanks, the production of external floating roof API 650 duplex stainless steel tanks is simple and the steel consumption is less. However, the central drainage system of external floating roof API 650 duplex stainless steel tanks should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.
The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve API 650 duplex stainless steel tanks work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
