Introduction
An LN₂ Cryogenic Tank is a specialized pressure vessel designed for the storage and handling of liquid nitrogen (LN₂) at ultra-low temperatures, typically around −196°C. These tanks are widely used in industrial, medical, laboratory, and research applications, ensuring safe containment, minimal boil-off, and precise dispensing of liquid nitrogen.
At NORDSTONE., we design and manufacture ASME-certified LN₂ Cryogenic Tanks with state-of-the-art vacuum insulation, high-strength construction, and full compliance with international standards, including ASME Section VIII, NB, PED, and ISO 21011.
What is an LN₂ Cryogenic Tank?
An LN₂ Cryogenic Tank is a double-walled, vacuum-insulated pressure vessel engineered to store and transport liquid nitrogen safely and efficiently. The inner vessel holds the LN₂, while the outer shell provides structural support and protects the insulation vacuum. Proper design minimizes thermal losses, controls boil-off, and ensures safe pressure management.
Key components include:
- Inner storage vessel constructed from stainless steel or nickel-based alloys
- Outer protective shell with thermal and mechanical support
- Vacuum insulation with multilayer reflective insulation to minimize heat ingress
- Pressure relief valves and safety devices for boil-off gas management
- Level, pressure, and temperature instrumentation
- Inlet and outlet connections for filling, dispensing, and venting
- Optional mobility features for transport applications
LN₂ tanks are essential for cryogenic storage, process applications, and medical gas systems, maintaining high purity and safe handling.
