Use cases for pressure Aluminum Cylinders.
Applications for aluminum gas cylinders range from industrial and commercial to personal and recreational.
– Industrial and manufacturing applications, where they store and transport gases for various processes and applications.
– In medical applications, hospitals and other healthcare facilities use them to store and transport medical gases.
– Aerospace applications, where they store and transport gases for use in aircraft and other aerospace applications.
– Personal and recreational use, such as camping, hiking, and other outdoor activities.
Durability and longevity of Aluminum Gas Cylinders
One key advantage of using Aluminium bottles is their durability and longevity. Unlike traditional steel cylinders, Aluminium tanks are resistant to corrosion and rust, making them ideal for various industrial and commercial applications. Additionally, they are less likely to deform or crack under pressure, which means they can be used for extended periods without deteriorating or becoming damaged.
Good corrosion resistance
Corrosion resistance is one of the primary uses for non-ferrous metal gas cylinders. Since different aluminium alloys possess unique chemical properties, the range and degree of corrosion resistance can vary.
Good heat transfer
Aluminum alloy boasts thermal conductivity several times that of steel, making it one of the highest thermally conducting materials, second only to copper.
High specific strength
Aluminum stands out among structural materials as having a lower density and a greater specific strength (ratio of tensile strength to density) than steel.
This trait makes it more suitable for mobile gas cylinders with lighter equipment weight, decreasing energy usage while saving costs during transportation.
Type 3 Gas Cylinders – Fully-wrapped carbon composite
Type 3 gas cylinders feature a thin and lightweight aluminum liner fully overwrapped with carbon composite. They offer weight savings over Type 2 cylinders (up to 30%). They can also be filled to higher pressures (up to 300 bar), offering increased capacity for the same size cylinder. Type 3 lightweight gas cylinders are ideal for applications where portability and power are essential, such as home oxygen therapy and medical oxygen cylinders in ambulances.
Suitable applications include:
Ambulatory oxygen
Portable field testing
Drone/UAVs
Fuel cell applications
Aerospace and military
Calibration
Applications of Aluminium Cylinders
Aluminium alloy gas cylinders are highly versatile and suitable for a broad range of professional and personal uses:
- Industrial and Manufacturing: Used for storing and transporting gases essential for process control, automation, and machinery operations.
