API Std 650 mechanically-anchored flat-bottom tanks pontoon openings

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API Std 650 mechanically-anchored flat-bottom tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.
Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.API 650 "welded storage tanks" API Std 650 mechanically-anchored flat-bottom tanks is a standard developed and issued by the American Petroleum Institute (API), which specifies the minimum requirements for the design, manufacture, installation and inspection of welded storage tanksCustomer concept: customer first Guided by market changes and guided by customer needs, we design the optimal product solutions and provide the best after-sales service Partners: to reach a balance of interests with all stakeholders, to build a harmonious coexistence and win-win cooperation,API Std 650 mechanically-anchored flat-bottom 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.
