ASTM A131 plates API Std 650 flat-bottom oil storage tanks
The floating roof is the top cover floating on the liquid level, so the sealing performance of API Std 650 flat-bottom oil storage tanks API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API Std 650 flat-bottom oil storage tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.
Due to irregular operation of API Std 650 flat-bottom oil storage tanks welding, there are many weld deformations during the construction process. Before specific operations, most construction units have formulated relatively complete construction plans and set up special welding process instructions, but the operators have not fully performed welding in accordance with various process guidance requirements and construction specifications, resulting in some quality problems of oil storage tanks. How can we reduce or even avoid this kind of situation?
Surface Inspection of low-pressure storage tank Component PartsBefore assembly, unless already so certified by shop inspectors, all sidewall plates or sections and roof and bottom plates shall be inspected for thickness, freedom from injurious defects, and soundness of any welded joints.Check of Dimensions of API Std 650 flat-bottom oil storage tanks Component PartsAll formed plates and curved sections shall be checked for conformance with the planned dimensions and cross section. For unusual repairs the inspector should keep a record of measurements taken at sufficient intervals to constitute a satisfactory record.Check of Chemical and Physical Property DataThe inspector shall check the material being assembled by the lists of the plates from the mill, their heat numbers, chemical analyses, and mechanical properties as given on mill reports and shall see that copies are available to be attached to the Manufacturer’s report.

Management information and high efficiency. Because of the rapid flow of API Std 650 flat-bottom oil storage tanks goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
