Description
Spherical Storage Tank ASME
This is industrial storage at its absolute largest scale. The ASME certified spherical storage tank — commonly known as a Horton sphere — is the gold standard for storing massive volumes of pressurized gases and liquids at refineries, terminals, pipeline hubs, and major industrial facilities worldwide.
Key Specifications
- Spherical pressure vessel design for maximum volume-to-surface-area efficiency
- Full ASME Boiler and Pressure Vessel Code certification
- Designed for LPG, propane, butane, NGL, and other pressurized products
- Heavy-plate steel construction with precision welding throughout
- Elevated on structural steel support columns
- Includes industrial-grade valve manifolds, instrumentation, and safety systems
- Engineered for decades of continuous industrial service
Why Spherical?
The sphere is the most structurally efficient shape for containing internal pressure. Compared to cylindrical tanks, spherical storage vessels require less steel per unit of volume stored, distribute stress more evenly across the shell, and minimize the number of structural support points needed. For very large volumes — where a cylindrical tank would be impractically long or require excessive wall thickness — spherical design is the engineering solution of choice.
Industrial Applications
Spherical storage tanks operate at petroleum refineries for LPG and intermediate product storage, at NGL fractionation plants, at propane and butane wholesale terminals, at petrochemical complexes, and at major pipeline interchange points. They represent critical infrastructure in the energy supply chain.
A Major Investment
At $810,000, this spherical storage tank is a significant capital expenditure — but for the facilities that need this level of storage, it’s essential infrastructure that serves for decades. This is a purpose-built industrial pressure vessel with no substitute at this scale.
