API standard 650 uplifting tanks gauge wells

Our quality control department will do inspection for details of the steel materials API standard 650 uplifting tanks before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.Allowable Design Stresses
The maximum allowable design stresses for the API standard 650 uplifting tanks materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the API standard 650 uplifting tanks tank wall Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressureWe had a wonderful trip in Phuket Island, Thailand At the end of 2019, in order to thank employees for their hard work for a year and enrich their lives, our company organized a pleasant trip to Phuket Island, Thailand The tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27 We took off in Zhengzhou at about 5 o'clock in the afternoon on the 22th December,API standard 650 uplifting tanks. Breathing valve: The function of the oil tank breathing valve is to adjust the oil and gas pressure in the tank. When the pressure in the tank is too high, part of the excess oil and gas will be discharged through the breathing valve to reduce the pressure in the tank; when the pressure in the tank is too low, through breathing The valve sucks in air from the outside of the tank to increase the pressure in the tank and keep it constant with the atmospheric pressure. The breathing valve is usually installed at the top of the oil tank.
