Welding of Large Steel storage tank Primary Components
a)Longitudinal and circumferential shell joints and joints that connect the API Std 650 unanchored liquid-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).The thickness of the overburden on the top of the API 650 oil tank should not be less than 0.5m.

1. The prefabrication of wall panel shall be processed in strict accordance with the requirements of the drawings, and inspection records shall be made.
2. After the wall panel is rolled, it should be placed on the platform for inspection with a template. In the vertical direction, use a straight-line template to check, the gap should not be greater than 2 mm, and in the horizontal direction, use an arc-shaped template to check, and the interval should not be greater than 4 mm.
3. When wall panels are rounded, attention should be paid to prevent irreversible plastic deformation caused by external forces. After rolling, it should be placed on the platform for inspection, and then placed on the prepared mold.The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel API Std 650 unanchored liquid-storage tanks plates.
