6061 aluminum shapes API Std 650 anchored tanks

Selection of nominal diameter D of API 650 storage tank. In the design calculation of API 650 storage tank, the bottom plate thickness is the net plate thickness, that is, the actual thickness minus the corrosion allowance. In the design and calculation of API Std 650 anchored tanks wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.

Generally, the snow load in the API Std 650 anchored tanks construction area should be considered before the design and construction of the tank. The snow load in the API Std 650 anchored tanks construction area has an impact on the tank roof design and operation, especially in the area with large snow load, the roof load of large storage tank with large diameter increases. Anti freezing, heat preservation and waterproof measures shall be taken for the additional facilities of storage tanks, such as pumps, breathing valves, flame arresters, detection instruments and thermal insulation layers.

All API Std 650 anchored tanks fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole, and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.

The company has an entrepreneurial team composed of highly educated and high-quality talents, whose leaders graduated from famous universities. As the first group of teams engaged in e-commerce industry in China, it witnessed the rapid development of e-commerce, accumulated rich steel professional knowledge and formed a scientific management system.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the API Std 650 anchored tanks steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its API Std 650 anchored tanks steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
