Ground Supported Flat Bottom Storage Tank - Caldwell

Ground Supported Flat Bottom Storage Tank (FB) Reservoir (RES) when diameter is larger than height or Standpipe (SP) when diameter is smaller than height DEFINITION A welded carbon-steel cylindrical water storage tank built at grade-level on a steel-reinforced concrete foundation.From Floating Tops to Flat Bottoms PetrolPlazaThe clearance between the floating roof and the shell is sealed by a device called a rim seal.The floating roof may be one of any number of designs,as described later.The tank shell and bottom are similar to those of an ordinary vertical cylindrical fixed roof tank.The two categories of floating roof tanks are External Floating Roof (EFR)Foundations of aboveground steel tanksc) flat bottom without slope It can be applied in the small tanks where the removing of the water dropped inside into the tank is not required.d) flat bottom with single slope.Can be applied where the diameter D 30 m.This type of bottom requires sloped foundation and the construction of the shell must assure its vertical position.2.
