API 650 unanchored liquid-storage tanks overturning stability

The interior of API 650 storage tanks to be internally lined or coated must have all edges rounded to a minimum of 3 mm radius. Internal welds must be completely seal welded, ground smooth, and free from API 650 unanchored liquid-storage tanks surface porosity, pockets, and high spots. Remove weld spatter. Vendor as specified on API 650 storage tanks drawing must perform additional surface preparation.

Ultrasonic testing can find the internal defects of API 650 unanchored liquid-storage tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API 650 unanchored liquid-storage tanks and so on metal oil tanks. The feature of this method is convenient and fast.
