Welding of Large Steel Storage Tank Primary Components
a)Longitudinal and circumferential shell joints and joints that connect the API 650 cylindrical tanks annular bottom plates together.
b)Joints that connect sections of compression rings and sections of shell stiffeners together. Backup bars may be used for these joints with complete penetration and complete fusion detail.
c)Joints around the periphery of a shell insert plate.
d)Joints that connect the shell to the bottom, unless a method of leak checking is used (see Q.8.2.1).
