2. The Five Basic Typesof Water Tanks
- 1 . Leg Tank/Multi-Column
- 2 . Pedesphere/Waterspheroid(single pedestal)
- 3 . Fluted Column/Hydropillar(single pedestal)
- 4 . Composite( single pedestal)
- 5 . Ground Storage Tank/Flat Bottom
3. Leg/Multi-Column
- 1.Double Ellipsoidal (DE)-Smaller sized leg tanks (50,000 to
150,000 gallons) are referred to as DEs. This term means the roof
to side shell connection is ellipsoidal and the bottom to side
shell connection is also ellipsoidal, hence double
ellipsoidal.
- Torus Bottom (TB) - Larger sized leg tanks (200,000
- gallon and larger) have a torus bottom shape to them,
- hence they are commonly referred to as TBs.
4. Double Ellipsoidal (DE) 5. Double Ellipsoidal (DE)
- Riser transcends directly
- into the bottom of the tank bowl

39. Corrosion A natural electro-chemical activity where a
processed compound of materials (steel) returns to its lowest
possible energy state (iron oxide). 40. 41. Corrosion Occurs
Through the Action of an Electrochemical CellFour Elements: 1 .
Anode2 . Cathode 3 . Metallic Path 4 . Electrolyte 42. Protective
Coatings 43. Coatings Provide Corrosion Protection inTwo Different
Ways: 1 . Barrier Protection Inhibit the corrosionprocess by
eliminating the presence ofelectrolyte (most paint films) 2 .
Galvanic Protection Sacrificial or cathodic protection (zinc-rich
primer) 44. Surface Preparation is vital in cleaning the surface of
all contaminants and it also provides a profile for the paint film
to anchor into (i.e. good adhesion). 45. Paint Consists of Three
Main Components: 1 . Resin2 . Pigment 3 . Solvent 46. Generic
Coating Types Typically Used inthe Water Tank Industry: 1.
Epoxy(Two Component) Used for primer, intermediate and interior
immersion Hard, abrasive resistantChalk & fade when exposed to
ultraviolet light 2. Zinc(Two Component) Used for primer on
interior or exterior Galvanic/sacrificial properties 3.
Polyurethanes(Two Component) Used for exterior of tanks.Strong
color/gloss retention performance 47. Generic Coating Types
Typically Used inthe Water Tank Industry:(continued)4. Acrylics(One
Component) Used for exterior repainting/overcoating existing
tanksGood adhesion propertiesImposes least amount of stress to
older paint 5. Aluminum Alkyds(One Component) Used for exterior
repainting/overcoating existing tanksStill some of these tanks
