API 650 aboveground petroleum storage tanks site-specific response spectra

Aftershock Level Earthquake (ALE)
This design case shall be applicable only when regulations or project documents specifically require the tank system to be designed or evaluated for aftershocks.
If the outer tank is not designed as a secondary containment (i.e. it serves as vapor barrier and pressure boundary only and is not constructed of API 620 material suitable for the inner tank API 650 aboveground petroleum storage tanks), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.Pipeline transportation of API 650 oil tank is not less than the maximum consumption of 3 to 5 days. The daily operating time of API 650 aboveground petroleum storage tanks office buildings and fuel oil equipment is 12-16 hours; for high-end residential hotel buildings, the daily operating time is 16-24 hours.FANALCA is the biggest motorcycle factory in Columbia. Meanwhile, it is the only distributor in Colombia for Japanese Honda. We began to cooperate with each other since 2017. We supply SAPH370, SAPH440 and so on automobile steel coils to them. As our products quality is proved to be satisfied during their production, they have been one of our stable customers, and give repeat orders about automobile steel every year.Before welding the API 650 aboveground petroleum storage tanks, the professional skills of the welding personnel shall be fully assessed to ensure that the operators meet the corresponding welding qualifications. According to the technical standards, scientific and feasible process requirements are actually formulated. In the process of welding the edge plate of API 650 aboveground petroleum storage tanks, electric welding is required on one side of the edge plate, so that the edge plate has a free shrinkage effect and greatly reduces the residual stress of the welding seam.The company's after-sales service team is a high-quality professional team.
