A841 Gr B Cl 2 plates API 650 ground supported flat-bottom tanks
The API 650 ground supported flat-bottom tanks external floating roof tank of API 650 tank has many advantages, and its application range is more and more wide. It is a kind of storage tank with a bright future. The well-designed internal floating roof tank of API 650 tank is the best and least investment method to control evaporation loss of API 650 ground supported flat-bottom tanks Fixed roof tank.
Usually, the wind load in the API 650 ground supported flat-bottom tanks construction area should be considered before the tank design and construction. The wind load in the API 650 ground supported flat-bottom tanks construction area has an impact on the stability and economy of the API 650 ground supported flat-bottom tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API 650 ground supported flat-bottom tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.
Any joints between the adjacent sections of API 620 oil storage tank stiffening rings, as shown in Figure Q-1, shall be made so that the required moment of inertia of the combined ring-shell section is provided. Weld joints between adjacent sections shall be made with full-thickness and full-penetration butt-welds. Stiffening-ring butt-welds may employ metal backing strips. Backing strips and the associated welding shall be made in a manner that provides a smooth contour in the rat hole and all other weld joint ends. All weld passes shall be started at the rat hole and other weld joint ends and shall be completed by moving away from these ends. Passes shall be overlapped away from edges to provide a smooth continuous weld.
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 650 ground supported flat-bottom tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
Box making, door-to-door: fill in the packing plan: box making time, ship name, voyage number, customs declaration number, transfer port, destination port, gross weight, number of pieces, volume, door point, contact person, telephone number, etc., and arrange the train shift 1-2 days before the closing date (two days before the ship's date). Internal loading: fill in the packing plan: ship name, voyage number, customs declaration number, transfer port, destination port, gross weight, number of pieces, volume, cabin number, etc., and arrange the train shift 1-2 days before the closing date (two days before the ship's date).
