API Std 650 aboveground welded storage tanks stiffeners

In view of the characteristics of container transportation, such as high added value, low cargo damage and short time, our company takes more consideration of port collection and distribution conditions, port facilities, flight density and route coverage when choosing ports For the convenience of customers, as well as the safety of goods,API Std 650 aboveground welded storage tanks. test procedure
The inner tank shall be opened to the atmosphere, and a sufficient amount of water shall be added to the inner tank to balance the upward pressure against the inner tank bottom produced by the pneumatic test of the outer tank; as an alternative, the pressure between the inner and outer tanks can be equalized. API Standard 620 Air pressure shall be applied to the space enclosed by the outer tank equal to at least the design gas pressure but not exceeding a pressure that would overstress either the inner or outer tank.The company's products API Std 650 aboveground welded storage tanks have excellent quality, reasonable prices and strong usability, and are well received by users. Survive by quality, expand the market with integrity, continuously research and develop new products, expand varieties, to meet market demand, and make the company continue to grow. The needs and interests of users are our high philosophy of service and commitment, and customer satisfaction is our eternal pursuit.Design calculations and drawings required API Std 650 aboveground welded storage tanks for the fabrication and erection of each API 650 tank. A drawing index for each API 650 tank is required and shall be re-submitted each time drawings are revised and re-issued.When the day light gradually decreases, the temperature of oil in the API Std 650 aboveground welded storage tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API Std 650 aboveground welded storage tanks will also decrease. When the pressure in the API Std 650 aboveground welded storage tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API Std 650 aboveground welded storage tanks through the open vacuum valve, which is the "suction" process of the oil tank.
