Spherical Tanks Designed for High-Pressure and Cryogenic Use

Uniform stress distribution

Internal pressure creates membrane tension that stays consistent across the whole vessel. No hot spots. No localized stress concentrations. That means lower fatigue risk over decades of pressure cycling.

High structural efficiency

The shape converts internal pressure into tensile stresses distributed evenly through the vessel wall. This efficient load path means more of the material's yield strength is available for pressure containment rather than managing bending moments or stress concentrations.

Reduced material thickness

For a given pressure and diameter, a spherical tank requires significantly less wall thickness than a cylindrical tank of equivalent capacity. Lower thickness translates directly to reduced steel weight and lower material procurement costs.

High-pressure storage capability

This configuration handles volatile liquids and compressed gases at elevated pressures. Common services include anhydrous ammonia, LPG, NGL, LNG, gasoline, oxygen, and nitrogen across midstream, downstream, and petrochemical facilities.

Cryogenic and low-temperature compatibility

The same geometry can be used across ambient, low-temperature, and cryogenic service conditions, but material selection must change accordingly. Carbon steel may be used for ambient service, while stainless steel or nickel alloys are typically specified for cryogenic applications to maintain toughness at low temperatures.

ASME-compliant design

Every spheroid tank gets built to ASME Section VIII, Divisions 1 or 2. The documentation package includes material certs, NDE reports, and the final data report. Repair work follows the National Board R Certificate of Authorization when needed.
