Aboveground API 650 flat-bottom tanks

The bottom plate of the vertical API 650 flat-bottom tanks directly contacts with the foundation soil, which is suitable for the flexible foundation, and its settlement characteristics are quite different from that of the rigid foundation. For the settlement calculation of the foundation of a vertical API 650 flat-bottom tanks, the one-way compression layered sum method can be used. The calculation method is to divide the foundation soil into several layers of compression within the calculation depth of the foundation settlement, and then find the sum. The calculation method of the compression amount of each layer is the same as the calculation method of the compression amount under the condition of no lateral deformation.Allowable Design Stresses
The maximum allowable design stresses for the API 650 flat-bottom 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.The welded API 650 tank in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure API 650 flat-bottom tanks is permitted when additional requirements are met.The company's business philosophy: customer satisfaction is the most important measure of our work performance; employees are the company's most important wealth; the improvement of employees' quality and professional knowledge is the growth of the company's wealth; employees' welfare and living standards are the concrete embodiment of the company's business performance; product and service quality are the lifeblood of the company's development; brand is the company's products and A mirror of service; recognition of the market is the foundation of the company's survival.We have a professional production team and high-quality production equipment, and we also have a great API 650 flat-bottom tanks advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the API 650 flat-bottom tanks production of high-quality steel plates, steel pipes and other products that meet customer requirements.
