API 650 aboveground oil storage tanks snow load

In order to prevent the deformation of the bottom of metal vertical API 650 aboveground oil storage 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 aboveground oil storage 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.

Heat-affected zone impact specimens shall be taken across the weld and as near the surface of the material as is practicable. The API 650 aboveground oil storage tanks material specimens shall be of sufficient length to locate the notch in the heat-affected zone after etching. The notch shall be cut approximately normal to the material surface to include as much heat-affected zone material as possible in the resulting fracture. Impact test specimens shall be cooled to the temperature stated in Q.22.

This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API 650 aboveground oil storage tanks storage of petroleum, petroleum products. and other liquid products.
