TPED/DOT/GB Aluminium Gas Cylinders—ISO 9000 Certified Supplier
Since 1998, DSW Industry has been a trusted manufacturer of high-quality aluminum cylinders and bottles, offering capacities ranging from 580 grams to 40 litres.
DSW is a leading global supplier of custom-engineered and standard fabrication services, tailored to meet diverse customer requirements—whether for bespoke solutions or routine applications.
Our aluminium alloy gas cylinders are widely used to contain calibration gases, mixed speciality gases, ultra-high-purity gases, oxygen, carbon dioxide, and even carbon monoxide.
These aluminum bottles and cylinders play a crucial role in the filling, storing, and transporting various gases.
Applications that prioritise minimising overall weight often favour aluminium tanks due to their significantly lighter weight compared to alloy steel cylinders.
What are the sizes of gas cylinders?
Use cases for pressure Aluminum Cylinders.
Aluminum gas cylinders are used in various applications, 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
DSW’s aluminium bottles store or transport gases for various applications, including ultra-high-purity gases for electronics manufacturing, speciality and calibration gases, industrial gas, medical oxygen, food and beverage-grade CO2, SCUBA, fire and rescue, alternative fuel, and aerospace.
lightweight aluminum cylinders
According to the requirements of GB 11640-2011 Aluminum Alloy Gas Cylinders, the body material of aluminum alloy gas cylinders should generally be 6061 aluminum alloy, which has the performance of sound cold and hot processing, corrosion resistance, low temperature, fatigue, etc.
GB 11640-2011 Aluminum Alloy Seamless Gas Cylinders allow the cylinder to use other aluminum alloy materials with good intergranular corrosion resistance and process performance. Still, it should pass the corrosion and constant load crack resistance tests.
