Aluminum Cylinders with TPED/DOT/GB
DSW Industry offers a wide range of aluminum cylinders for transporting and storing industrial gas, medical oxygen, food and beverage-grade gas, and alternative aerospace gases.
Those gases are utilized mainly in the chemical, mining, and hospitality industries.
Industry aluminium cylinders also store ultra-high-purity gases for electronics manufacturing, specialty and calibration gas, industrial gas, medical oxygen, food and beverage-grade CO2, SCUBA, fire and rescue, alternative fuel, and aerospace.

Aluminum also has a lower chance of sparking, which makes it ideal for holding gas.
Because aluminum passes cylinder inspection so frequently, it’s less likely to rust, making it preferable to steel.
Aluminum possesses a range of appealing qualities, and among them, its lightweight nature, toughness, and corrosion resistance stand out as the three most notable advantages. In operations involving gas cylinders, the ability to handle numerous canisters simultaneously becomes crucial. Therefore, the ease of transportation and storage plays a significant role.
Considering these cylinders operate under tremendous pressure, minimising the risk of breakage or puncture becomes imperative, which could lead to hazardous situations. Fortunately, aluminum’s robustness and durability enable it to withstand accidental impacts and collisions without substantial damage.
Furthermore, the materials contained within gas cylinders can be highly toxic and potentially corrode the metal components over time. To counteract this, aluminum alloys are employed, providing exceptional resistance to corrosion for the metal canisters, valves, and other integral parts associated with the cylinders.
In summary, aluminum’s lightweight nature, toughness, and corrosion resistance offer substantial advantages in the realm of gas cylinder operations. They facilitate efficient handling, enhance safety by withstanding potential hazards, and ensure long-lasting performance.
The benefits of aluminum gas cylinders
Aluminium bottles offer several advantages over steel for gas cylinders: lighter weight, improved corrosion protection, low-temperature resistance, and the potential to be recycled at end-of-life.
Good Heat Transfer
The thermal conductivity of aluminum alloy is many times greater than steel’s. It is second only to Copper in terms of thermal conductivity.
High Specific Strength
Aluminum is a common structural material with a lower weight and higher specific strength than steel.
Higher explicit strength materials can result in lighter equipment for portable gas cylinders, reducing energy consumption and transport costs.
The crystal structure of aluminium alloy is face-centred cubic.
Because the face-centred, cubic crystal structure exhibits a strong coordination ability, aluminium alloy gas cylinders are not prone to brittle cracks when used in shallow temperatures.
In addition, aluminum’s strength and lightness will not be affected, nor will its mechanical properties. Aluminium alloy can resist low temperatures below -269°C without special requirements.
The manufacturing process of aluminum bottle
Punching and drawing method
The aluminum alloy seamless gas tube is formed by heating the aluminum billet and punching it into a short and thick cup, then drawing and closiitcup. This is the primary method of manufacturing aluminum alloy seamless gas tanks.
Cold extrusion refers to the process of creating seamless aluminum alloy gas bottles via cold extrusion of billet and subsequent closure. This technique has straightforward procedures and low costs; however, larger tonnage presses are required for this processing method.
Punching and Stretching Method
Deep drawing refers to drawing an aluminum alloy plate into a long cup-shaped part and then closing off one end. While its wall thickness can be uniform, its material utilization rate and process complexity are low and costs high compared to alternative manufacturing techniques, leading to limited use among manufacturers.
The spinning method refers to gas bottles manufactured using an aluminum alloy plate. With materials like aluminum alloy, spinning can help maximize the plastic potential of the material such that deformation can reach over 70%; one clamping and spinning session is enough to achieve results usually only achieved after multiple stretching and annealing sessions are necessary. Stretch spinning is one of the methods for manufacturing aluminum bottles, particularly suitable for small-batch product production.
