A516 grade 70 plates API 650 self-anchored tanks
storage tanks API 650 self-anchored tanks designed in accordance with the rules and guidelines of API 650 are called API 650 storage tanks. API 650 is a control rule for welded storage tanks that work normally in the normal pressure range.
Tank cracks are common API 650 self-anchored tanks defects, mainly including tank wall cracks, internal cracks, weld zone cracks. The reason for these defects may be that the defects not exceeding the standard existed in the early stage of API 650 self-anchored tanks construction, which become obvious after the later use. Or in the process of using the API 650 self-anchored tanks, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.
When as-rolled plate material complies with impact test requirements as specified here, the material need not be normalized. If, as with ASTM A516, the specification prohibits impact test without normalizing but otherwise permits as-rolled plates, the API 620 welded storage tanks material may be ordered in accordance with the above provision and identified as “MOD” for this API modification.
