API Std 650 aboveground oil storage tanks site-specific response spectra
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 Std 650 aboveground oil storage tanks insert plate shall be round with diameter no less than 24 in. and no greater than 42 in.
Standard API 650 tank calls for calculations based on the specific gravity of the liquid product being stored. This permits the thickness of the steel API Std 650 aboveground oil storage tanks needed as well as other specifications of how the tank is built to be determined by the weight of the API 650 tank.
The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous API Std 650 aboveground oil storage tanks pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.
}The mechanical seal of floating roof API Std 650 aboveground oil storage tanks relies on mechanical force to press the sealing steel plate tightly against the tank wall, so that it can slide on the tank wall and avoid gap as far as possible. However, mechanical seal has high requirements for the geometry of storage tank and poor adaptability, so mechanical seal is rarely used in newly built floating roof API Std 650 aboveground oil storage tanks.
