Seismic design for API standard 650 SUG I tanks
Generally, the building area temperature of the API standard 650 SUG I tanks should be considered before the tank design and construction. The temperature in the API standard 650 SUG I tanks building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the API standard 650 SUG I tanks, the higher the corresponding pressure and the more volatile loss.
The tank shall be filled with water to the design liquid level unless height is limited as noted in API 620 standard Q.8.1. After the tank is filled with water and before the pneumatic pressure is applied, anchorage, if provided, shall be tightened against the hold-down brackets. All welds in the API standard 650 SUG I tanks shell, including the corner weld between the shell and the bottom, shall be visually checked for tightness.
BBN excels in the design, fabrication and erection of API-650 tanks. API (American Petroleum Institute) has created a set of standards for above ground API standard 650 SUG I tanks oil storage, but these tanks are also commonly used for gasoline, chemical and water storage. API-650 storage tank solutions range in size from an 8’ -0” diameter shop fabricated tank up to and beyond 100’ -0” diameter field erected storage tank applications.
