API 650 aboveground welded storage tanks rim seals
Oil storage tank with floating roof structure: The floating roof in the API 650 aboveground welded storage tanks oil storage tank can effectively reduce the volatilization consumption of oil, because the gas space on the oil liquid surface in the floating roof storage tank is small, the exhaust volume is low, and the breathing loss is very small. That can reduce the volatilization loss caused by the "big breath" of the API 650 aboveground welded storage tanks. Strengthen the inspection and maintenance of API 650 aboveground welded storage tanks: regularly check the sealing conditions of oil storage tanks, and check and maintain important auxiliary equipment to ensure good sealing performance.
The thickness of the API 650 aboveground welded storage tanks annular bottom plates shall be in accordance with Table Q-4 (for steel or aluminum, as applicable). The thicknesses shown are minimums. The ring of annual plates shall have a circular outside circumference, but it may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with Q.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by a weld as required by API 620 oil tank 5.9.5 except when a full-penetration weld is used or required (see Q.7.1.1). Butt-welds in annular plates shall be not closer than 12 in. from any vertical weld.
This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API 650 aboveground welded storage tanks storage of petroleum, petroleum products. and other liquid products.
