A633 grade D plates API standard 650 aboveground petroleum storage tanks

API 650 petroleum storage tanks use lightning protection, anti-static, and fire protection measures. The internal corrosion protection should be determined according to the API standard 650 aboveground petroleum storage tanks storage medium, and the outer wall corrosion protection should be determined according to the soil quality of the buried tank.

Inspection of weld and micro crack of API standard 650 aboveground petroleum storage tanks: the inner and outer surface of API standard 650 aboveground petroleum storage tanks, weld and heat affected zone shall be observed by naked eyes first. 100% ultrasonic testing or 100% penetrant testing are carried out for butt welds of API standard 650 aboveground petroleum storage tanks. For the defects found by 100% magnetic particle inspection, dye detection, 100% ultrasonic inspection or 100% penetrant inspection, the radiographic inspection shall be used again to ensure the accuracy of the test results.

A refrigerated tank may be a single-wall insulated tank or a double-wall tank that consists of an inner tank for storing the refrigerated liquid and an outer tank that encloses an insulation space (which usually has a lower gas pressure) around the inner tank. A double-wall tank is a composite tank, and the outer tank is not required to contain the product of the inner tank. In a double-wall tank, differences in API Standard 620 tank materials, design, and testing exist between the inner and outer tanks.
