API 650 self-anchored tanks structural period of vibration

The API 650 self-anchored tanks external floating roof tank of API 650 tank has many advantages, and its application range is more and more wide. It is a kind of storage tank with a bright future. The well-designed internal floating roof tank of API 650 tank is the best and least investment method to control evaporation loss of API 650 self-anchored tanks Fixed roof tank.

Aftershock Level Earthquake (ALE)
This design case shall be applicable only when regulations or project documents specifically require the tank system to be designed or evaluated for aftershocks.
If the outer tank is not designed as a secondary containment (i.e. it serves as vapor barrier and pressure boundary only and is not constructed of API 620 material suitable for the inner tank API 650 self-anchored tanks), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.

Treatment of API 650 self-anchored tanks welding defects:
1. Lack of fusion: once found, it should be shoveled and grinded off before re welding.
2. Incomplete penetration: over standard defects shall be removed and re welded. When welding on both sides, the shallow side of the groove can be grinded and shoveled to expose the welding root on one side, and then the welding is repaired.
3. Slag inclusion: over standard defects shall be removed and re welded.
4. Crater: weld to full after grinding.
5. Air hole: if the internal air hole exceeds the standard, it shall be welded again after being removed by grinding shovel, and the surface air hole shall be removed by grinding wheel and then repaired.
