API standard 650 vertical welded storage tanks resistance to design loads

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, API standard 650 vertical welded storage tanks and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

Anti corrosion of API standard 650 vertical welded storage tanks:
After using for a certain period of time, it is necessary to check the corrosion protection of the API standard 650 vertical welded storage tanks. If necessary, the outer wall of the metal oil tank should be painted with new anti-corrosion paint to ensure that the outer wall of the API standard 650 vertical welded storage tanks does not fall off and has good waterproof and rust resistance.
API standard 650 vertical welded storage tanks cleaning:
The long-term use of API standard 650 vertical welded storage tanks will produce impurities on the tank wall and deposit on the tank bottom, resulting in tank corrosion to leakage. According to the safety standard of oil tank, the API standard 650 vertical welded storage tanks shall be cleaned and derusted regularly to ensure the quality of oil stored and the safety of oil tank equipment.

The thickness of the API standard 650 vertical welded 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.
