API 650 tanks shell compression

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

Determination of Required Capacity
The aggregate capacities required for any vent valves, pressure-relieving valves, and/or vacuum-relieving valves to be provided should be determined as follows:
a)For thermal breathing and product movement, the rules given in API 2000 shall be followed. The required capacity as the result of the product movement into the tank API 650 tanks given in API 2000, shall be multiplied by the ratio of the absolute tank pressure to atmospheric pressure (14.7 lbf/in.2 absolute).
b)For supplemental safety pressure-relieving devices to take care of extra venting capacity required in case of external fire exposure, the rules in API 2000 shall be followed.

All edges of the inner wall of the API 650 petroleum storage tank to be lined or coated must be rounded and flat to a minimum radius of 3mm. The API 650 tanks internal welding seam must be completely sealed welding, with a smooth surface and no air holes, air pockets and local protrusions. Remove welding spatter. As specified in API 650 petroleum storage tank design drawings, the seller must perform additional surface treatment.
