API standard 650 fixed roof tanks testing of the roof

Oil tank is often used to store crude oil, diesel oil, gasoline and other oil. The main structure of API standard 650 Fixed roof tanks is composed of tank top, tank wall, tank bottom and accessories. The API standard 650 fixed roof tanks should be inspected after the completion of construction, and the detection methods of different structure positions are different. Tank wall inspection: for the newly built oil tank, water filling test shall be conducted to check whether the tank wall is tight, and the appearance inspection shall be conducted for the tank wall plate and weld. Tank wall thickness detection: the oil tank wall thickness is mainly detected by ultrasonic wave, with high efficiency.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 standard 650 fixed roof 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.In API 650 oil storage tank, when the mixing ratio of combustible medium and air reaches a certain limit, it is easy to cause explosion. Therefore, it is necessary to add API standard 650 fixed roof tanks external floating roof to open cylindrical steel API standard 650 fixed roof tanks tank. At present, the external floating roof is most suitable for large-scale API 650 oil storage tank in China, ranging from 20000, 30000, 50000 cubic meters to 100000 cubic meters.The company has always adhered to the corporate purpose of “improving benefits, creating wealth, benefiting employees, and giving back to the society”.
