4.5m diameter API standard 650 self-anchored storage tanks

Weld inspection of API standard 650 self-anchored storage tanks, vertical oil tank wall plate: In the welding inspection process of oil tank wall plate, attention should be paid to the defects of thick wall plate, such as incomplete penetration, incomplete root fusion and cracks. If there is a root incomplete penetration defect, it is necessary to open the weld joint with carbon arc air gouging and grinding machine grinding, or even weld through, and then weld again after the defect is removed.

Temperature Range: The provisions in this appendix are considered suitable for API standard 650 self-anchored storage tanks design metal temperatures from + 40°F to –60°F, inclusive. In general, refrigerated tank primary components include those components whose failure would result in leakage of the liquid being stored, those exposed to the refrigerated temperature, and those subject to thermal shock. Further definitions of such components are provided in API Standard 620 tank R.1.4.2 and R.1.4.3.

The API 650 tank Standard has the built in flexibility to be used in building tanks to store a wide variety of products while ensuring the structural stability of the API standard 650 self-anchored storage tanks tank.
