API 650 SUG I tanks structural shapes

Welding of Large Steel storage tank Primary Components
a)Longitudinal and circumferential shell joints and joints that connect the API 650 SUG I 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).

Lateral braces between outer bay rafters must be provided if asymmetrical structural shapes are used for rafters and if the API 650 SUG I tanks API 650 tanks are located in areas subject to earthquakes. The bracing must be adequately sized for the seismic zone specified.

Our client purchase more than 900 tons pipe API 650 SUG I tanks from India. And we do the inspection for each one pipe before shipment.During the inspection, the inspector saw that the surface of the square pipe kept the original color of the stainless steel, no fracture, no depression and other quality defects was found.

The head of API 650 SUG I tanks etc. vertical oil tank is the end cover on the top of vertical oil tank. It is used to separate the oil stored in the tank and the medium outside the tank, and also used to bear the pressure on the top of the vertical oil tank. The quality of the head is closely related to the long-term safety of the API 650 SUG I tanks. The head surface can be divided into convex shape, cone shape and flat shape according to its shape. The oil tank head can not be disassembled after welding.
