API Std 650 cylindrical welded storage tanks allowable longitudinal membrane compression stress in shell

,API Std 650 cylindrical welded storage tanks., Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API Std 650 cylindrical welded storage tanks is related to the actual working conditions. The design service life of most oil tanks is 20 years, and some of them are 10-15 years. Generally, none of them is less than 10 years. However, the design service life of API Std 650 cylindrical welded storage tanks is on the one hand, which is an ideal state, but there are many objective factors in the actual process, it is impossible to achieve the designed service life. How to effectively increase the service life of API Std 650 cylindrical welded storage tanks?API 620 Tank Design
The designer of these large tanks API Std 650 cylindrical welded storage tanks shall supply the data on superimposed loadings to be assumed for the foundation design or, if there are no foundations, for direct loading on the subgrade. A slab or mat may be provided to support the superstructure and shall be considered to distribute the load more evenly over a lower natural subgrade compared with merely stripping, leveling, and rolling the existing grade.
For simple spheroids or tanks of similar design, in which the distribution of the imposed weights shifts because the liquid level in combination with the vapor pressure may change the shape of the tank, the designer shall consider the possibility of such a change.API 650 petroleum storage tank has the advantages of high safety: the API Std 650 cylindrical welded storage tanksinner floating plate floats on the liquid surface, so that the liquid phase has no evaporation space, which can reduce the evaporation loss by 85% to 90%. At the same time, the API 650 petroleum storage tank blocks the air and liquid storage through the floating disk, which reduces air pollution and reduces the degree of fire risk.we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.Expect in the API Std 650 cylindrical welded storage tanks goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen API Std 650 cylindrical welded storage tanks product development technology, excellent production team, hand strict quality control, sales and after-sales service.
