API 650 flat-bottom steel tanks wind load on tanks

The lip seal of floating roof storage tank, API 650 flat-bottom steel tanks relies on the sliding contact between elastic lip and tank wall. This kind of seal has strong applicability, but the requirements of manufacturing technology and material selection are high, and the determination of elastic seal also exists. The secondary seal of floating roof storage tank, API 650 flat-bottom steel tanks is to add a seal on the basis of primary seal. It is proved by experiments that the secondary seal can reduce the liquid consumption by more than 50%, and has a more significant effect in safety.

The materials used in the construction of Appendix Q oil tanks may be subject to severe pitting, cracking, or rusting if they are exposed to contaminated test water for extended periods of time. The Purchaser shall specify a minimum quality of test water that conforms to Q.8.3.2 through Q.8.3.8. After the water test is completed, the tank API 650 flat-bottom steel tanks shall be promptly drained, cleaned, and dried.

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 flat-bottom steel 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.
