API 650 special tank seismic design factors

The lip seal of floating roof storage tank, API 650 special tank relies on the sliding contact between elastic lip and tank wall. This kind of seal has strong applicability, but the requirements of manufacturing technology and material selection are high, and the determination of elastic seal also exists. The secondary seal of floating roof storage tank, API 650 special tank is to add a seal on the basis of primary seal. It is proved by experiments that the secondary seal can reduce the liquid consumption by more than 50%, and has a more significant effect in safety.

The API 650 special tank outer tank, which is not in contact with the vaporized liquefied gas, may be of single-welded lap or single-welded butt construction when the thickness does not exceed 3/8 in.; at any thickness, the API 620 oil tank outer tank may be of double- welded butt construction without necessarily having full fusion and penetration. Single-welded joints shall be welded from the outside to prevent corrosion and the entrance of moisture.

Determination of API 650 oil tank container: The total volume should be determined according to factors such as transportation mode and API 650 special tank 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.

The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve API 650 special tank work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
