API Std 650 welded steel oil storage tanks with a mat foundation
The floating roof is the top cover floating on the liquid level, so the sealing performance of API Std 650 welded steel 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 welded steel 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.
The thickness of the API Std 650 welded steel oil storage tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.57 in. The nozzle neck is seamless steel pipe and conforms to ASTM A53, Grade A; the materials in the tank wall and reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank walls are fully radiographed, double-welded butt joints. The adequacy of the reinforcement and attachment welds shown in Figure F-7 shall be determined.To determine the length of the nozzle neck within the limits of reinforcement, the smaller of the following calculated values shall be used:(2.5)(0.625) = 1.56 in. (2.5)(0.375) + 0.75 = 1.69 in.
As we know, the vertical metal tank, API Std 650 welded steel oil storage tanks is welded by many components, and the welding quality of each component determines the later use effect of the API Std 650 welded steel oil storage tanks. Professional API Std 650 welded steel oil storage tanks manufacturers should have a set of professional skills in the welding process of API Std 650 welded steel oil storage tanks. Key points for weld inspection of vertical metal tank, API Std 650 welded steel oil storage tanks: 1. It is strictly forbidden to paint the welds before passing the inspection. 2. Visual inspection shall be carried out for welds. 3. NDT shall be carried out on the weld.
