API standard 650 aboveground steel oil storage tanks details of welding

The bottom plate of the vertical API standard 650 aboveground steel oil storage tanks directly contacts with the foundation soil, which is suitable for the flexible foundation, and its settlement characteristics are quite different from that of the rigid foundation. For the settlement calculation of the foundation of a vertical API standard 650 aboveground steel oil storage tanks, the one-way compression layered sum method can be used. The calculation method is to divide the foundation soil into several layers of compression within the calculation depth of the foundation settlement, and then find the sum. The calculation method of the compression amount of each layer is the same as the calculation method of the compression amount under the condition of no lateral deformation.Temporary Openings after Hydrostatic Test
When approved by the Purchaser in writing, and only in the case of tanks which when complete have no shell penetrations, it is permitted to restore by welding up to four temporary shell openings after the hydrostatic test in accordance with the provisions of this section. Each temporary opening shall be restored by the insertion of a shell plate that matches the thickness and specification of adjacent shell material, and is welded into place with full fusion butt-welds. The API standard 650 aboveground steel oil storage tanks insert plate shall be round with diameter no less than 24 in. and no greater than 42 in.The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API standard 650 aboveground steel oil storage tanks API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.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.
