Low Temperature Storage Spheres
Spheres are used to store low temperature liquids and pressurized gases. This method of storage has the advantage of reduced exterior surface for a given storage volume as compared to all other possible shapes.
The majority of spheres operate at or above a minimum low temperature of -50°C (-58°F), and require exacting control of temperature to preserve the quality of the product contained within the vessel. Therefore, an insulation material that is impermeable to water or water vapor, and retains its thermal properties over a prolonged period of time is preferred.
Consult Pittsburgh Corning's Technical Services for guide specifications covering the latest information about design, installation and maintenance of FOAMGLAS® insulation systems.
Typical Configuation for Low Temperature Spheres:
- A single or double layer system of prefabricated curved insulation segments (SHS) is generally sufficient for this temperature range.
- The insulation system shall be fully bonded to the substrate with PC® adhesive appropriate for the application conditions.
- The joints in the insulation system shall be sealed with PC® adhesive / sealant appropriate for the application conditions.
- Coating or cladding appropriate for the environmental conditions shall be installed to protect insulation system from weather and mechanical damage.
