5086 aluminum tube API Std 650 flat-bottom oil storage tanks

In order to prevent the deformation of the bottom of metal vertical storage tank, API Std 650 flat-bottom oil storage tanks during welding, the number of welders should be reasonably distributed. When welding metal vertical API Std 650 flat-bottom oil storage tanks, personnel and welding position shall be reasonably allocated according to the actual situation of welding personnel, and random welding is not allowed.

API 620 Tank Standard Post-heat Treatment (Stress Relief)
The post-heat treatment now performed on pressure vessels is of established value, although the mechanism by which the improvement is realized may be open to debate. Post-heat treatment of API Std 650 flat-bottom oil storage tanks tank sections when the plate thickness exceeds 11/4 in. is required as stated in 5.25. In special cases, the possibilities of post-heat treatment after erection should be explored. Post-heating an insulated tank may be possible if an ample source of heat is readily available and if the rigidity of the tank is adequate.
The thermal stress-relief treatment performed on pressure vessels is recognized as a means for reducing the probability of brittle failures.

Determination of API 650 oil tank container: The total volume should be determined according to factors such as transportation mode and API Std 650 flat-bottom oil storage tanks fuel supply cycle. For train and ship transportation, the maximum consumption is not less than 20-30 days; the maximum consumption for automobile transportation is not less than 5-10 days.
