API standard 650 aboveground petroleum storage tanks tank joints

API standard 650 aboveground petroleum storage tanks Nondestructive testing is a technical means to detect the weld defects of large vertical tank and judge whether the weld is qualified by using the characteristics of sound, light, magnetism and electricity without damaging the tested object. Common nondestructive testing methods: ultrasonic testing (UT), magnetic particle testing (MT), liquid penetrant testing (PT) and X-ray testing (RT).

Welding of Large Steel Storage Tank Primary Components
a)Longitudinal and circumferential shell joints and joints that connect the API standard 650 aboveground petroleum storage 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).

When API 650 storage tank is designed, when the design pressure is small F2 kPa, the impact of air pressure on the API standard 650 aboveground petroleum storage tanks tank wall thickness is not considered in the tank wall design.
