6063 aluminum bar API 650 unanchored liquid-storage tanks
storage tanks API 650 unanchored liquid-storage tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 petroleum storage tank detailed standard specifies the design, processing, welding, inspection and installation procedures of the storage tank.
Temporary Openings after Hydrostatic TestWhen 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 650 unanchored liquid-storage tanks insert plate shall be round with diameter no less than 24 in. and no greater than 42 in.
The bottom plate of the vertical API 650 unanchored liquid-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 650 unanchored liquid-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.
we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years.
