API 650 ground supported liquid storage tanks shell support

API 650 storage tank stipulates that if the thickness of the lower wall panel obtained by calculating the anti-overturning moment is greater than the thickness of the API 650 ground supported liquid storage tanks hydrostatic pressure test (both do not include the corrosion allowance).

Crack treatment of API 650 ground supported liquid storage tanks weld area: find out the crack tip with ray or ultrasonic flaw detection, drill cut-off holes at both ends of the crack with the cut-off method, the hole depth is slightly greater than the crack depth, or groove (crack stop groove) is made by angle grinder at both ends of the crack, shovel and grind the whole crack, and grind it into a suitable groove; use radiographic inspection and dye detection to verify that the crack has been completely excavated, and finally repair welding.

When the anchorage is designed to meet the requirements of API Standard 620 tank Q.3.6.4.2, the foundation should be designed to resist the uplift that results from three times the design pressure with the tank full to the design liquid level. When designing to any of the conditions in this paragraph, it is permissible to utilize friction between the soil and the vertical face of the ringwall and all of the effective liquid weight.
