Horizontal Storage Tanks

Horizontal storage tanks can be built to a variety of sizes and can be furnished for atmospheric pressure, or designed for internal and external pressure. All materials are available including stainless steel, nickel alloys and reactive metals.

Horizontal storage tanks are typically less cost effective than vertical tanks, however, they are ideal in areas where vertical space may be limited, and can also be integrated into a building's structural steel.

We can also design a system around your storage tank to include pumps, pressure/temperature measuring equipment, and lifting/filling equipment.

Our general design parameters for horizontal storage tanks is:

  • 14"-0" Diameter (4.2m)

  • 15,000 psi internal pressure


  • Flanged and dished
  • Conical or Toriconical
  • Flat or sloped
