The height of API 650 self-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 650 self-anchored tanks wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.

Tank cracks are common API 650 self-anchored tanks defects, mainly including tank wall cracks, internal cracks, weld zone cracks. The reason for these defects may be that the defects not exceeding the standard existed in the early stage of API 650 self-anchored tanks construction, which become obvious after the later use. Or in the process of using the API 650 self-anchored tanks, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.

Foundations and subgrade shall safely carry the weight of the tank API 650 self-anchored tanks and its contents when the tank is filled with water to the highest level required for a hydrostatic test or other water-loading operations, even though the tank itself may be designed for some lesser density of liquid. However, in cases where the character of the soil justifies it and a competent soil expert advises it, allowance may be made for the relatively short duration and intermittent nature of the water loadings if suitable account is taken of all such loadings that may be expected to occur during the life of the tank, including not only those loadings that are incidental to periodic repetitions of the hydrostatic test in accordance with 7.18 but also water-filling operations for gas-freeing purposes.

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, API 650 self-anchored tanks and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

The mode of iron and API 650 self-anchored tanks steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API 650 self-anchored tanks steel logistics.
