Nordstone | High-Pressure Gas Cylinders

Engineered for Extreme Pressure Applications

A High-Pressure Gas Cylinder Storage Vessel is a robust pressure-rated container designed for the safe storage and handling of industrial gases at extremely high pressures. These vessels are engineered to withstand pressure ranges from 150 bar to 700 bar (and above), depending on the application, gas type, and safety requirements.

Used extensively in industrial, medical, specialty gas, energy, and defense sectors, these vessels ensure reliable storage with maximum safety and lifecycle performance.

What Is a High-Pressure Gas Cylinder Storage Vessel?

A High-Pressure Gas Cylinder Storage Vessel is:

•
A thick-walled pressure container
•
Designed as cylindrical, seamless, or welded constructions
•
Capable of storing gases like oxygen, nitrogen, hydrogen, argon, helium, CO₂, natural gas (CNG/LNG), and specialty gases
•
Manufactured using high-strength materials with rigorous testing standards

Depending on the design, these vessels may be:

✔
Single-cylinder type
✔
Manifolded cylinder banks (cylinder bundles)
✔
Tube trailers / skid-mounted vessels
✔
Modular banks for stationary storage
