API 650 stipulates that an open tank should be provided with a wind-resistant ring to ensure that the naphtha steel storage tank tank body maintains its roundness when subjected to wind. There are no hard and fast rules for vault API 650 storage tanks. It can be determined by comparing the equivalent wall height with the maximum height of the unreinforced tank wall.

Welding inspection of bottom plate of naphtha steel storage tank, vertical oil tank: During the fabrication and installation of naphtha steel storage tank, the bottom edge plate is welded first. According to the requirements of the technical standard, penetrant inspection is required for the weld of edge plate at the bottom of naphtha steel storage tank, that is, penetrant testing is required for each weld bead priming, filling and capping. In the process of testing, if any defect is found, it shall be repaired immediately. After the repair, the surface coloring penetrant test shall be conducted again until the test result is qualified.

API 620 crude oil tank piping materials made according to ASTM A333 and A350 may be used at naphtha steel storage tank design metal temperatures no lower than the impact test temperature required by the ASTM specification for the applicable material grade without additional impact tests. For temperatures below those allowed by the ASTM specification, the following paragraph shall apply.
