Product Overview
Vacuum tubing is designed using high-vacuum multi-layer insulation technology, consisting of an inner tube, outer tube, and interlayer insulation materials. It is specifically engineered for long-distance transportation of cryogenic liquids (liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, etc.), effectively reducing cold loss and ensuring safe delivery.
Core Advantages
- Ultra-low Cold Loss: Interlayer vacuum degree ≤1×10⁻¹⁰ Pa*m³/s, leakage rate ≤1×10⁻⁸ Pa*m³/s, with no frost formation after 24-hour liquid nitrogen transportation.
- Pressure & Corrosion Resistance: Supports a maximum working pressure of ≤4MPa, compatible with harsh media such as LOX (Liquid Oxygen), LIN (Liquid Nitrogen), and LAr (Liquid Argon).
- Modular Design: Flange/plug-and-play connections enable quick on-site installation and maintenance.
- Eco-friendly & Safe: Made of food-grade 304 stainless steel, compliant with USP VI/USDA standards.
Models & Application Fields
| Model Series | Applicable Scenarios | Typical Media | Industry Sectors |
|---|---|---|---|
| DN15-DN50 | Laboratory gas pipeline systems, medical oxygen generators | LOX/LIN/LHe | Medical, Biotechnology |
| DN65-DN150 | LNG refueling stations, steel plant liquid oxygen transportation | LNG/LO2/LAr | Energy, Metallurgy |
| DN150+ | Aerospace fuel transportation, deep-sea engineering | LH2/LHe | Aerospace, Deep-sea Exploration |
| Flexible Vacuum Tubing | Mobile equipment, low-temperature chemical reaction devices | LOX/LN2 | Chemicals, New Energy |
Key Performance Indicators (DN25 as Example)
| Parameter | Value/Feature |
|---|---|
| Inner Tube Material | SUS304 stainless steel (cryogenic resistance: -196℃) |
| Outer Tube Material | SUS304 stainless steel (double-layer structure) |
| Interlayer Insulation | Multi-layer aluminum foil reflector + aerogel composite (thermal conductivity ≤0.005 W/m*K) |
| Operating Pressure | ≤4MPa (high-pressure versions available upon request) |
| Design Temperature | -196℃~+60℃ |
| Vacuum Service Life | ≥10 years (leak rate ≤1×10⁻¹⁰ Pa*m³/s) |
| Compressive Strength | Passed ISO 11631 hydraulic test |
| Explosion-proof Certification | Compliant with ATEX/IECEx standards |
Packaging Method
- Inner Packaging: EPE pearl cotton + air column bag buffering, individually sealed per tube to prevent shock and scratches.
- Outer Packaging: 5-layer BC corrugated cardboard box with wooden frame support inside, max load per box ≤200kg.
- Special Protection: Tube mouth sealed with moisture barrier film + desiccant packets to adapt to high-humidity marine environments.
Storage Guidelines
Environmental Requirements:
- Temperature: 10℃~30℃ (avoid direct sunlight).
- Humidity: ≤60% RH (requires dehumidification equipment).
- Keep away from heat sources ≥2m; no contact with acidic/alkaline substances.
Stacking Specifications:
- Boxes ≥15cm off the ground, with wooden boards between layers.
- Max stack height ≤8 layers (single box weight limit: 200kg).
Shelf Life:
- Standard storage: 24 months (vacuum degree must be checked every 6 months).
- Extended storage: Recheck vacuum degree ≤5×10⁻² Pa before reuse.
