API 650 mixed material tanks impulsive spectral acceleration parameter

Generally speaking, the duration of the "exhalation" of the API 650 mixed material tanks is longer than that of the "inhalation" of the API 650 mixed material tanks every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the API 650 mixed material tanks location, open area of the API 650 mixed material tanks, atmospheric pressure, filling degree of API 650 mixed material tanks, etc. When the API 650 mixed material tanks is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.

Our quality control department will do inspection for details of the steel materials API 650 mixed material tanks before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

API 650 petroleum storage tank stipulates that if the thickness of the lower siding obtained by calculating the anti-overturning moment is greater than the thickness of the API 650 mixed material tanks hydrostatic pressure test (both do not include the corrosion margin), the calculated thickness of the above siding required by the hydrostatic pressure is It should also be increased by the same proportion, unless special analysis is performed to determine the seismic overturning moment and corresponding stress at the bottom of each layer of API 650 petroleum storage tank wall.
