API standard 650 ground supported flat-bottom tanks emergency overflow drains

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 standard 650 ground supported flat-bottom tanks wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's API standard 650 ground supported flat-bottom tanks steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole API standard 650 ground supported flat-bottom tanks steel transportation industry.

To scientifically evaluate the remaining service life of the API standard 650 ground supported flat-bottom tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API standard 650 ground supported flat-bottom tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API standard 650 ground supported flat-bottom tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.

On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children. With the development of the society, disabled children gets increasing concerns and help from all walks of life. Fortunately, Chinese Government gives high concern to the handicapped children and has built Children Welfare Institutes all over the country to guarantee their lives.
