A633 grade C plates API Std 650 liquid storage tanks
API 650 petroleum storage tank stipulates that if the thickness of the lower siding obtained by calculating the anti-overturning moment is greater than the thickness of the API Std 650 liquid storage tanks hydrostatic pressure test (both do not include the corrosion margin), the calculated thickness of the above siding required by the hydrostatic pressure is It should also be increased by the same proportion, unless special analysis is performed to determine the seismic overturning moment and corresponding stress at the bottom of each layer of API 650 petroleum storage tank wall.
API Std 650 liquid storage tanks Pressure-relieving DevicesTanks shall be protected by automatic pressure-relieving devices that will prevent the pressure at the top of the tank from rising more than 10% above the maximum positive gauge pressure except as provided in API 620 standard 9.2.2.Where an additional hazard can be created by the exposure of the tank to accidental fire or another unexpected source of heat external to the tank, supplemental pressure-relieving devices shall be installed. These devices shall be capable of preventing the pressure from rising more than 20% above the maximum positive gauge pressure. A single pressure-relieving valve may be used if it satisfies the requirements of this paragraph and 9.2.1.
Inspection of API Std 650 liquid storage tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API Std 650 liquid storage tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API Std 650 liquid storage tanks, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API Std 650 liquid storage tanks bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.
