API standard 650 welded tanks for oil storage qualification of welders

API standard 650 welded tanks for oil storage belongs to metal oil tank. Metal oil tank is a kind of vessel made by welding steel plate. The common shapes of metal tank are vertical metal tank, horizontal metal tank and spherical metal tank. The advantages of API standard 650 welded tanks for oil storage etc. metal oil tank are good sealing, not easy to leak, can be installed with heating and insulation function, metal tank can withstand high internal pressure, large vertical metal tank such as API standard 650 welded tanks for oil storage also has the characteristics of small floor space and large storage capacity.

Uplift on Foundation
For API Standard 620 tanks with an internal design pressure less than 1 lbf/in.2 gauge, the uplift shall be taken as the smaller of the maximum uplift values computed under the following conditions:
a)The internal design pressure times 1.5 plus the design wind load on the shell and roof.
b)The internal design pressure plus 0.25 lbf/in.2 gauge plus the design wind load on the shell and roof.

API 650 is used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API standard 650 welded tanks for oil storage API 650 tanks with diameters between 8'-300', which are suitable for refineries, terminals, pipeline facilities and other projects.
