storage tank api 650 reinforcing plate fillet welds

The foundation design of the storage tank API 650 should meet the requirements of foundation stability and deformation, that is, the storage tank api 650 foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the storage tank api 650 and cause distortion and deformation of the tank wall and bottom plate.

The design metal temperature of storage tank api 650 each component exposed to the liquid or vapor being stored shall be the lower of the following:
a)The minimum temperature to which the tank contents will be refrigerated, including the effect of subcooling at reduced pressure.
b)The minimum metal temperature anticipated when the atmospheric temperature is below the refrigerated temperature (see 4.2.1). The effectiveness of the insulation in keeping the metal temperature above the expected minimum atmospheric temperature shall be considered.

Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the storage tank api 650 tank wall. Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressure.

In December of 2015, our regular India customer sent us an inquiry for storage tank api 650 pipe. The inquiry requires no negative tolerance in both pipes’ outer diameter and pipe wall. After two weeks’ discussion, he put the order of 275 tons to us. The pipes are finished within just one month. Our customer come to our factory to inspect the quality and tolerance, all the products are well meet his demand. The pipes are arriving to Nhava Sheva port, customer is very happy with our products and service during the process.
