Ningbo Mingxin and Tianjin Dongxiang to Launch Next-Generation Liquid Helium ISO Tank, Setting New Standards in Cryogenic Storage and Transport
The Ecological Week is a premier gathering for the gas industry, attracting top executives and leading enterprises. The new product launch, a dedicated session within the event, highlights breakthroughs in cryogenic storage and transport technology and is expected to be a focal point for attendees.
A Partnership of Industry Pioneers**
With over five decades of expertise in cryogenic equipment manufacturing, Ningbo Mingxin has earned international recognition for its production capabilities and quality certifications, exporting to more than 30 countries. Tianjin Dongxiang is a renowned specialty gas company, distinguished by its leadership in helium volume and application technology, serving diverse high-tech sectors.
Liquid helium is an indispensable resource for advanced industries such as quantum computing, aerospace, and medical imaging. However, conventional ISO tanks have long suffered from inefficiencies—limited mobility, excessive boil-off losses, and inadequate protection against extreme conditions—hindering the scalability of helium logistics. The newly developed tank overcomes these barriers through a series of proprietary innovations that ensure reliable performance at -269°C, the temperature required to maintain helium in its liquid state.
Key Technological Breakthroughs
1. Advanced Insulation for Extended Hold Time**
The tank features a high-vacuum multi-layer insulation (MLI) system, achieving internationally advanced thermal performance. This technology drastically reduces heat ingress, enabling long-distance transport and prolonged storage without significant product loss.
2. Optimized Liquid Nitrogen Tube Design
A novel liquid nitrogen tube structure, combined with an innovative connection method between the aluminum shield and the tube, provides sustained thermal protection, minimizing helium evaporation over extended periods.
3. Specialized Internal Surface Treatment
Internal components undergo a unique surface treatment process that significantly reduces outgassing in the vacuum space, preserving vacuum integrity and insulation efficiency throughout the tank's service life.
4. Multi-Stage Labyrinth Support Structure
To accommodate the extreme temperature swing from ambient to -269°C, engineers developed a labyrinth-type multi-stage support system. This design ensures mechanical stability and safety under complex transportation conditions, preventing stress-induced failures.
5. Precision Assembly Process**
A proprietary precision assembly technique guarantees exact coaxiality and spatial alignment along the entire tank length. This meticulous approach is critical to maintaining long-term lossless storage performance.
6. Lightweight Construction for Greater Efficiency**
The use of thin-wall lightweight aluminum alloys for the liquid nitrogen cold shield reduces overall weight while enhancing thermal insulation. This not only improves payload capacity but also boosts transport economics, making helium logistics more viable.
Event Highlights
At the launch, senior executives and technical experts from both companies will present the new product's capabilities and discuss industry trends. An interactive consultation session will allow attendees to engage directly with the development team, explore technical details, and identify collaboration opportunities.
With the liquid helium storage and transport sector poised for rapid growth, this joint initiative injects new momentum into the industry's high-quality development. The partnership between Ningbo Mingxin and Tianjin Dongxiang exemplifies how cross-sector collaboration can drive technological progress and address global supply chain challenges.
