Annual inspection is an inspection during operation to ensure the safety of atmospheric storage tanks during the overhaul period, at least once a year. Comprehensive inspection is a more comprehensive inspection of atmospheric storage tanks according to a certain inspection cycle.

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.
