API standard 650 aboveground welded storage tanks for small internal pressures

Oil tank accessories are an important component of metal oil tanks. Common accessories of API standard 650 aboveground welded storage tanks include manholes, light holes, oil measuring holes, breathing valves, safety valves, and fire extinguishers. The functions of these accessories are different. Some are to ensure the storage quality of various oil products, some are to ensure the normal operation of oil products receiving and dispatching, and some are to ensure the safety management of API standard 650 aboveground welded storage tanks, etc.

In this project, an elemental area of API 620 oil storage tank wall is constructed of ASTM A516 Grade 55 steel plate subjected to a meridional unit force, T1, of 2620 lbf/in. tension and a latitudinal unit force, T2, of 2880 lbf/in. compression. The meridional radius of curvature, R1, is 132 in., and the length of the normal from the surface to the axis of revolution, R2, is 409 in. The joints in the wall are spot-radiographed, double-welded butt joints, and no corrosion allowance is required.
The problem in this example is to graphically find the minimum thickness of tank wall required for the given conditions (see API 620 tank standard 5.10.3.3).
Solution: As determined from Table 5-1, the maximum, allowable tensile stress value, Sts, for ASTM A516 Grade 55 steel plate in simple tension is 16,500 lbf/in.2. Since the compressive stress is latitudinal, the governing value of R for this situation is R1, or 132 in.
