API 650 self-anchored tanks allowable stresses

API 620 crude oil tank piping materials made according to ASTM A333 and A350 may be used at API 650 self-anchored tanks design metal temperatures no lower than the impact test temperature required by the ASTM specification for the applicable material grade without additional impact tests. For temperatures below those allowed by the ASTM specification, the following paragraph shall apply.API 650 petroleum storage tank body design is mainly the design of tank bottom, API 650 self-anchored tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API 650 self-anchored tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.Square hollow section S355J2H to Turkey. In January of 2015, our customer from Turkey chose us as their supplier of seamless RHS EN10219 S355J2H with a trail order of 120 tons. They required DNV test for the MTC and each tube. DNV inspector tested all the tubes and MTC. When our customer received the reports, they gave us a second order of 852.5 tons. Since then we maintain a long time cooperation relationship.Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API 650 self-anchored tanks. The mechanical cleaning of the API 650 self-anchored tanks 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 650 self-anchored tanks 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.Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our API 650 self-anchored tanks service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's API 650 self-anchored tanks customer service to establish a good, comprehensive, full service system.
