Maximum design temperature of API Std 650 welded tanks for oil storage

Insulation Load
For API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API Std 650 welded tanks for oil storage roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.

For API 650 tanks Projection from outside of tank shell to extreme face of flange - plus or minus 5 mm. API Std 650 welded tanks for oil storage Elevation or radial location - plus or minus 6 mm. API 650 tanks Flange tilt in any plane, measured on the diameter across the gasket surface - plus or minus degree but not exceeding 5 mm. Flange bolt hole orientation - plus or minus 2 mm.

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 welded tanks for oil storage pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.

API Std 650 welded tanks for oil storage, Oil tanks can be divided into above ground storage tanks, underground storage tanks, offshore tanks and submarine tanks according to their installation positions. Oil tanks can be divided into crude oil tanks, fuel oil tanks, lubricating oil tanks, edible oil tanks, etc.. According to the use of oil tanks, oil tanks can be divided into production tanks, storage tanks, etc.. According to the external style, oil tanks can be divided into vertical tanks, horizontal tanks, etc.. According to the composition structure, oil tanks can be divided into fixed roof storage tank, floating roof tank, spherical tank, etc.
