API standard 650 welded steel oil storage tanks convective water parameters
API 650 internal floating roof oil tank is a volatile liquid storage tank with a combination of a dome tank and an internal floating roof structure, which is a floating roof assembled under the dome of the API standard 650 welded steel oil storage tanks storage tank. The combination of the vault roof outside the API 650 storage tank and the floating roof inside the tank has been widely used in gasoline, aviation kerosene and more volatile chemical liquids.
The specifications used in the design of large oil tanks, API standard 650 welded steel oil storage tanks mainly include American Petroleum Institute Standard API 650, Japanese Industrial Standard JIS B8501, British Industrial Standard BS2654 and Chinese National Standard GB50341 from a global perspective. The formulas used in each specification are based on the hoop stress in the membrane theory. Each specification is based on the performance characteristics of materials and the construction technology level of their respective countries to determine the allowable stresses and weld coefficients. Therefore, the calculation results of tank wall thickness of API standard 650 welded steel oil storage tanks with the same volume are sometimes quite different according to different specifications.
Qualifications of API 620 Storage Tanks ExaminersExaminers for tanks constructed according to the rules in this standard shall have had not less than 5 years experience in design, construction, maintenance and/or repair, or in the responsible supervision of the construction, maintenance and/or repair of various types of unfired pressure vessels and/or API standard 650 welded steel oil storage tanks tanks, including at least 1 year of experience in the construction or supervision of the construction of vessels or tanks by fusion welding. Satisfactory completion of a suitable course of training approved by the Purchaser or the Purchaser’s agent may be substituted for 3 of the 5 years experience. However, training cannot replace more than 6 months of the required experience on fusion-welding construction.
When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API standard 650 welded steel oil storage tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
We have efficient and quick logistic team service. We promise that after the customer places the order, the spot products will be shipped, processed, and cut on the same day. The steel API standard 650 welded steel oil storage tanks products will be shipped in 2-5 days according to the characteristics of the product. The company has always been adhering to the service concept of "integrity, pragmatism, enthusiasm" and dedicated to providing our customers with high-quality steel products and after-sales service.
