Shell Stiffening Rings for Tanks That Contain Liquid
Internal or external shell stiffening rings may be required to maintain roundness when the tank is subjected to wind, vacuum, or other specified loads. When API standard 650 carbon steel tank stiffening rings are required, the stiffener-to-shell weld details shall be in accordance with Figure Q-1 and Q.3.5.2 through Q.3.5.5.
Three-plate laps or butt-weld junctions in tank bottoms shall be not closer than 12 in. from each other or from the butt-welds of the annular plates.

API 650 is a control rule for welded storage tanks that work normally in the normal pressure range.We exported 352 tons SA387GR12CL2 steel plates to Vietnam. The Vietnam customer needed the SA387GR12CL2 steel plates for their tank fabrication project urgently. We are world class steel materials supplier and exporter. Other than regular fresh production, we also keep huge stocks, so as to meet urgent demands of our customers. For the 352 tons SA387GR12CL2 steel API standard 650 carbon steel tank plates, we collected from our warehouse and it only took us 3 days to arrange delivery. The customer was really impressed by our rapid shipping and spoke highly of our SA387GR12CL2 steel plates quality after use.Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API standard 650 carbon steel tank. The mechanical cleaning of the API standard 650 carbon steel tank can make the inside of the tank be thoroughly cleaned in multiple directions, and the cleaning quality is high, and the cleaned oil does not contain lumpy impurities. While the walls and roof of the API standard 650 carbon steel tank cannot be cleaned in multiple directions during manual cleaning, and the cleaning quality is not easy to be guaranteed. The oily sewage collected after cleaning usually contains a lot of lumpy impurities, and these oil products are difficult to clean.After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
