Description
ASME Spherical Storage Tanks
Spherical vessels are used where large volumes of pressurised or below-ambient-temperature liquefied gas must be stored — LPG and propane, and also ammonia, propylene and butadiene.
Why a sphere rather than a cylinder
A sphere spreads internal pressure evenly across its whole surface, so for a given pressure and volume it needs less steel than any other shape. That advantage grows with size, which is why bulk pressurised storage moves from horizontal cylinders to spheres above a certain capacity. A sphere also has the smallest surface area for its volume, which reduces heat gain — relevant when the contents are held below ambient temperature.
Specification
Built to ASME standard. Capacities are quoted to requirement; the reference configuration is 2,500 cubic metres, approximately 1,250 tons of LPG. Thermal insulation is specified according to service temperature.
Ordering
These are engineered, built-to-order vessels rather than stock items. Lead time, foundation design, transport and site assembly all depend on the specification and the destination.
Contact us with your capacity, service medium and site details for a quotation. We do not install or commission spherical vessels; that is specialist contractor work.
