TECHNIQUES METHODOLOGIES FOR TANK BOTTOM

As the whole shell of the crude oil storage tank is welded to the tank bottom plate,development of leaks on the tank bottom plate leaves the maintenance personnel with only two options (a) To do away with the leaky tank and erect a new one.(b) To replace / repair the tank bottom plate.Storage tanks,Fixed-roof tanks,Floating roof tanks ProductsCharacteristicsIndustryTypesAdvantagesOther usesConstructionFutureVersionsEquipmentFunctionSummaryOperationExamplesStorage tanks containing organic liquids,non organic liquids,vapors and can be found in many industries.Most storage tanks are designed and built to the American Petroleum Institute API-650 specification.See more on wermacStorage Tank DesignStorage tank prefabricating prepare three are sample plates,one sample plate for checking curvature of arch roof which the length is more than 2 meters,one inner arc sample plate for checking the deformation of the edge of vertical welded seam which the length is no less than 1 meter and one outer arc sample plate for checking the Storage Tanks - ULS Corporateabout the storage tank with arch roof,storage tank with inner floating roof and horizontal storage ble the bottom of tank.The steel plate of the center of bottom is center plate and peripheral 16.5m or more,cambered plate is used as margin plate.Tank shell is butt welded by many round steel plates.There are two types sleeve and
