Storage Tank Types
Vertical tanks (bolted and welded) (double wall and single wall)
- Open top tank (atmospheric) - Normally for petroleum products but can contain cooling water and fire water.
- Fixed roof tank (atmospheric, low pressure, high pressure) - Either be self supported or rafter/trusses supported depending on size.
- Cone roof tank (supported and self supported)
- Dome roof tank (supported and self supported)
- Internal floating roof tank (supported and self supported)
- Floating roof tank - Roof sits directly on top of product.
- External floating roof tank - Roof sits directly on top of product, open to atmosphere.
- Internal floating roof tank - Roof sits directly on top of product, tank has a fixed roof.
Horizontal tanks (double wall and single wall)
- Bullet tank - Presurized liquid gas tank.
Spherical tank - Presurized liquid gas tank.
