API standard 650 insulated tanks shell reinforcing plates

The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality API standard 650 insulated tanks products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

Generally speaking, the duration of the "exhalation" of the API standard 650 insulated tanks is longer than that of the "inhalation" of the API standard 650 insulated tanks every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the API standard 650 insulated tanks location, open area of the API standard 650 insulated tanks, atmospheric pressure, filling degree of API standard 650 insulated tanks, etc. When the API standard 650 insulated tanks is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.

The horizontal projection of the roof plate within the compression-ring region is 4.9 x 0.866 = 4.25 in., which fulfills the requirement of API 620 tank standard 5.12.5.1. The required area and horizontal projection can be provided by any of the standard angles listed in Table F-3.
Any of these angles may be used in accordance with the details of Figure 5-6, detail a or b, but if details c, h, or i in Figure 5-6 were intended, the net area of the angle must be calculated by deducting the area expected to be lost by corrosion from that part of the angle surface that is exposed to the interior of the tank.
