API Std 650 cylindrical welded storage tanks shell-to-bottom fillet welds

The mechanical seal of floating roof API Std 650 cylindrical welded storage tanks relies on mechanical force to press the sealing steel plate tightly against the tank wall, so that it can slide on the tank wall and avoid gap as far as possible. However, mechanical seal has high requirements for the geometry of storage tank and poor adaptability, so mechanical seal is rarely used in newly built floating roof API Std 650 cylindrical welded storage tanks.The thickness of the API Std 650 cylindrical 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.Above-ground API 650 storage tanks (vertical cylindrical flat-bottomed storage tanks) allow the storage of large volumes of goods at low cost. The only limitation is that they API Std 650 cylindrical welded storage tanks can be used under atmospheric pressure or relatively small internal pressure. There are different specifications and standards for the design of API 650 storage tanks.Team concept: respect, communication, coordination and symbiosisBusiness philosophy: leading by strategy, driving by innovation, creating valueManagement concept: goal oriented, efficient operation, stimulation of vitality and continuous improvementQuality concept: standard guidance, control process, craftsman spirit, leading serviceTalent concept: lifelong learning, give full scope to the talents, the sea refuses no riverInnovation concept: innovation is the first driving force for the company's high-quality developmentCustomer concept: taking customers as the center is the foundation of the company's survival and developmentIf you have steel demands in the near future, please send us inquiry in advance, as we have regular steel production plan and can arrange you a reasonable prodction time.
