Tank

A tank, abbreviated as TK, is used to store volumes of fluids for storage or as part of a process.

 

Tank Standards

API Standards

  • API Std 620 - Standard for Design and Construction of Large, welded, Low-pressure Storage Tanks
  • API Std 650 - Standard for Welded Steel Tanks for Oil Storage
  • API RP 651 - Recommended Practice for Cathodic Protection of Aboveground Storage Tanks
  • API RP 652 - Recommended Practice for Cathodic Protection of Aboveground Storage Tanks
  • API Std 653 - Standard for Tank Inspection, Repair, Alteration, and Reconstruction

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.
