In API 650, the allowable distance between vertical welds (also known as vertical joints or seams) in the shell of a welded steel storage tank is specified to prevent overlap of weld seams, which could affect the structural integrity of the tank.
According to API 650, Section 5.1.5.4:
- The minimum distance between adjacent vertical weld seams on the same shell course should not be less than 3 times the thickness of the shell plate or 500 mm (20 inches), whichever is greater.
This requirement ensures that there is sufficient separation between vertical welds to avoid concentration of stresses and to provide adequate strength in the tank shell.
For example, if the shell plate is 10 mm thick, the minimum distance between vertical welds would be 30 mm (3 × 10 mm). However, since 500 mm is greater than 30 mm, the minimum allowable distance would be 500 mm.
