API standard 650 tanks design thickness

Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the API standard 650 tanks tank wall. Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressure.

The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the API standard 650 tanks steel materials can be shipped immediately after passing the quality inspection.

Treatment of API standard 650 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.
