5652 aluminum tube API 650 insulated tanks

When the day light gradually decreases, the temperature of oil in the API 650 insulated tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API 650 insulated tanks will also decrease. When the pressure in the API 650 insulated tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API 650 insulated tanks through the open vacuum valve, which is the "suction" process of the oil tank.

In this project, an elemental area of tank wall used is constructed of ASTM A442 Grade 55 steel plate subjected to a meridional unit force, T1, of 4000 lbf/in.2 tension and a latitudinal unit force, T2, of 5060 lbf/in.2 compression. The meridional radius of curvature, R1, is 75 in., and the length of the normal from the surface to the axis of revolution, R2, is 300 in. The joints in the wall are of double-welded butt-joint construction with a tensile efficiency of 85%. A corrosion allowance of 1/16 in. is required.
The problem in this example is to graphically find the minimum thickness of tank wall required for the given conditions (see 5.10.3.3).
Solution: As determined from Table 5-1, the maximum allowable tensile stress value, Sts, for ASTM A442 Grade 55 steel plate in simple tension is 16,500 lbf/in.2. Since the compressive stress is latitudinal, the governing value of R in this situation is R1, or 75 in.

Large net shell API 650 tanks or net shell of tank API 650 insulated tanks is a tank top for the surface grid structure and the physical structure form of truss structures, thin shell structure is reasonable, mainly for the top using triangle net shell, socket type net shell or meridian reticulated shell technology for the design of API 650 insulated tanks large-scale tank top, its great spanning capacity and uniform stress, good rigidity, less material, convenient assembly, safe and reliable.
