Alclad 3003 aluminum plate API standard 650 unanchored flat-bottom tank

Generally, the building area temperature of the API standard 650 unanchored flat-bottom tank should be considered before the tank design and construction. The temperature in the API standard 650 unanchored flat-bottom tank 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 unanchored flat-bottom tank, the higher the corresponding pressure and the more volatile loss.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel API standard 650 unanchored flat-bottom tank products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.

Temporary Openings after Hydrostatic Test
When 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 standard 650 unanchored flat-bottom tank insert plate shall be round with diameter no less than 24 in. and no greater than 42 in.

Selection of nominal diameter D of API 650 storage tank. In the design calculation of API 650 storage tank, the bottom plate thickness is the net plate thickness, that is, the actual thickness minus the corrosion allowance. In the design and calculation of API standard 650 unanchored flat-bottom tank wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.
