Erection requirements for API 650 SUG I tanks

In order to prevent the deformation of the bottom of metal vertical API 650 SUG I tanks during welding, comprehensive control measures such as strict control of assembly geometry size, reasonable welding procedure, process control of welding deformation and rigid fixation are adopted during assembly welding. The specific methods are as follows:
1. Strictly control welding groove forming of API 650 SUG I tanks.
2. Strictly control the size of tank welding seam assembly.
3. Define the welding sequence of tank bottom plate.
4. Reasonable distribution of welders.

A refrigerated tank may be a single-wall insulated tank or a double-wall tank that consists of an inner tank for storing the refrigerated liquid and an outer tank that encloses an insulation space (which usually has a lower gas pressure) around the inner tank. A double-wall tank is a composite tank, and the outer tank is not required to contain the product of the inner tank. In a double-wall tank, differences in API Standard 620 tank materials, design, and testing exist between the inner and outer tanks.

The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API 650 SUG I tanks tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.
