Austrian Cryogenic Equipment Maker Sources 3003 O Aluminum Circles for LNG Storage Tanks
When an Austrian manufacturer of gas and liquid separation and purification equipment needed a reliable source of aluminum circles for cryogenic applications, it turned to Henan Yongsheng Aluminum Industry Co., Ltd. The 20-ton order of hot rolled 3003 O temper aluminum circles not only met the customer's strict technical requirements, but also delivered excellent spinning and stamping performance on the production line.
Customer Background
The client is based in Austria and specializes in the sales and manufacturing support of gas and liquid separation and purification equipment, as well as metal packaging containers and materials. Its core business focuses on the handling of cryogenic liquids such as liquid argon, liquid oxygen, and liquefied natural gas (LNG), where material reliability and low-temperature performance are critical.
Project Requirements
The customer required aluminum circles that could withstand extremely low temperatures while remaining highly formable for downstream processing. The order included four custom diameters, all supplied in hot rolled 3003 O temper for maximum ductility:
| Alloy | Temper | Thickness | Diameter | Quantity |
|---|---|---|---|---|
| 3003 | O | 3.0 mm | 710 mm | 20 Tons (total) |
| 3003 | O | 3.0 mm | 775 mm | |
| 3003 | O | 2.0 mm | 570 mm | |
| 3003 | O | 2.0 mm | 600 mm |
Applications
Thanks to the soft O temper and the superior formability of the 3003 aluminum alloy, the circles were used in two demanding cryogenic applications:
- Cryogenic Storage Tanks / Dewar Vessels: Used as the inner liner or outer shell of cryogenic liquid storage tanks, where the material must resist embrittlement and maintain sealing integrity at extremely low temperatures.
- Gas Separation & Purification Equipment: Used as pressure shells in separation towers, condensers, and liquid receivers, requiring consistent thickness and reliable weldability.
Results and Customer Feedback
All 20 tons were delivered on schedule and passed the customer's incoming quality inspection without issue. During production, the customer reported that the aluminum circles performed exceptionally well in both spinning and stamping processes — a direct result of the uniform grain structure and precise thickness control achieved through Yongsheng's hot rolling technology.
The customer confirmed: "The material is very easy to use for both spinning and stamping. It works very well."
