Erection requirements for API Std 650 closed top welded storage tanks

When roof plates, knuckle plates, compression rings, and manways and nozzles including reinforcement are primarily subjected to atmospheric temperature, the rules in API 620 oil tank standard Q.2.3 shall govern.
Large Welded storage tanks Secondary Components
In general, secondary components include those components that will not be stressed to a significant level by the refrigerated liquid, those whose failure will not result in leakage of the liquid being stored, those exposed to product vapors, and those that have a design metal temperature of –60°F or higher.This standard only applies to API 650 storage tanks API Std 650 closed top welded storage tanks with uniform bottom support and non-refrigerated service storage tanks with a maximum design temperature of not more than 93 degrees Celsius (200 degrees Fahrenheit).FANALCA (which is most big Motorcycle factory in Columbia ) ,And FANALCA is Japan Honda's only distributor in Colombia, they have visit our company in 2017 ,and they have purchase our SAPH370,SAPH440 coil 80-100 tons every month.

Combined with the stress characteristics of API Std 650 closed top welded storage tanks, plus the allowable stress, weld coefficient and additional wall thickness, the wall thickness calculation formula is complete. The allowable stress and weld coefficient are determined according to the material performance characteristics and construction technology level of each country. According to different API Std 650 closed top welded storage tanks standards, the calculation results of tank wall thickness are sometimes quite different.The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible.
