API Std 650 aboveground steel oil storage tanks roof and top angle joints

API 620 Tank Design
The designer of these large tanks API Std 650 aboveground steel oil storage tanks shall supply the data on superimposed loadings to be assumed for the foundation design or, if there are no foundations, for direct loading on the subgrade. A slab or mat may be provided to support the superstructure and shall be considered to distribute the load more evenly over a lower natural subgrade compared with merely stripping, leveling, and rolling the existing grade.
For simple spheroids or tanks of similar design, in which the distribution of the imposed weights shifts because the liquid level in combination with the vapor pressure may change the shape of the tank, the designer shall consider the possibility of such a change.The API Std 650 standard published by the American Petroleum Institute (API) is designed to provide the petroleum industry with welded steel tanks for use in the API Std 650 aboveground steel oil storage tanks storage of petroleum products and other liquid products commonly handled and stored by the various branches of the petroleum industry.In October, 2018, our Malaysia customer purchased 600 Tons CCS-AH36 Ship Building Steel Plates to use in their shipbuilding project .This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, API Std 650 aboveground steel oil storage tanks shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of API Std 650 aboveground steel oil storage tanks CCS-AH36 Ship Building Steel Plates.Usually, the soil resistance of the foundation should be considered before the design and construction of API Std 650 aboveground steel oil storage tanks. The soil endurance in the API Std 650 aboveground steel oil storage tanks construction area plays a decisive role in the basic cost of the tank. In areas with high soil resistance, not only the cost of foundation treatment can be greatly reduced, but also the ratio of height to diameter of storage tank can be obtained. Therefore, the investment cost of the API Std 650 aboveground steel oil storage tanks can be greatly saved in the area with large soil resistance.The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel API Std 650 aboveground steel oil storage tanks plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
