CSA G40.21 grade 50W plates API Std 650 stainless and carbon steel tank

API 620 Tank Design
The designer of these large tanks API Std 650 stainless and carbon steel tank 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.The internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API Std 650 stainless and carbon steel tank External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.To scientifically evaluate the remaining service life of the API Std 650 stainless and carbon steel tank, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API Std 650 stainless and carbon steel tank, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API Std 650 stainless and carbon steel tank are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.The results of adopting two-level API Std 650 stainless and carbon steel tank service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and API Std 650 stainless and carbon steel tank after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
