Cryogenic Flexible Hose
1. Product Overview
Our cryogenic flexible hose is a premium engineered solution designed for the safe and efficient transfer of cryogenic liquids and gases, including liquid nitrogen (LIN), liquid oxygen (LOX), liquid argon (LAR), and liquefied natural gas (LNG). Constructed with state-of-the-art materials, this hose combines exceptional flexibility with superior cryogenic performance, making it ideal for demanding industrial applications where rigidity and brittleness of traditional hoses pose significant risks.
Unlike standard hoses, our cryogenic flexible hose features a multi-layered construction that includes a seamless inner liner resistant to extreme low temperatures down to -196°C, reinforced stainless steel braiding for pressure containment, and an outer protective cover engineered to withstand mechanical abrasion and environmental exposure. This design ensures reliable performance in dynamic environments, such as loading/unloading terminals, storage facilities, and processing plants.
With a proven track record in international trade and B2B markets, our cryogenic flexible hose meets stringent global standards like ISO 21029, CGA V-6, and PED 2014/68/EU, providing peace of mind for operators handling hazardous cryogenic media. Whether you're in the energy sector, aerospace, or medical gas distribution, this hose delivers unmatched reliability and longevity.
2. Key Features
- Ultra-Low Temperature Resistance: Rated for continuous operation from -196°C to +60°C, preventing embrittlement and ensuring structural integrity during cryogenic transfers.
- High Flexibility: Bends easily without kinking, allowing for tight radii in confined spaces while maintaining flow efficiency.
- Superior Pressure Handling: Withstands working pressures up to 40 bar and burst pressures exceeding 120 bar, suitable for high-demand pumping systems.
- Corrosion and Permeation Resistance: PTFE or PFA inner liner minimizes gas permeation and chemical attack, extending service life.
- Safety Enhancements: Integrated anti-static properties and color-coded outer layers for easy identification of media type (e.g., blue for LOX).
- Customizable Lengths and Fittings: Available in lengths up to 30 meters with swaged or welded end fittings compatible with international standards like BS 1387 and DIN 28403.
- Lightweight Design: Reduces operator fatigue and installation complexity compared to rigid piping alternatives.

4. Application Scenarios
The versatility of our cryogenic flexible hose makes it indispensable across diverse industries. In the oil and gas sector, it excels in LNG transfer operations at marine terminals, where its flexibility accommodates vessel movements during loading and unloading, minimizing stress points and preventing leaks.
Aerospace applications benefit from its precision handling of LOX for rocket propulsion systems, ensuring safe fueling with zero contamination risk. In medical and laboratory settings, the hose facilitates the distribution of LIN for cryotherapy and sample preservation, maintaining purity and pressure integrity over extended distances.
Industrial gas producers rely on it for LAR cylinder filling stations, while chemical processing plants use it for intermediate cryogenic cooling processes. Additionally, it's deployed in superconductivity research facilities and food freezing lines, where consistent low-temperature performance is critical. Its adaptability to both stationary and mobile setups underscores its role in global supply chains.
5. Advantages
Choosing our cryogenic flexible hose offers distinct advantages over conventional alternatives. Its multi-layered architecture provides unparalleled resistance to thermal shock, reducing the incidence of cracks or failures common in single-material hoses exposed to rapid temperature cycling.
Engineered for minimal flow restriction, it optimizes transfer rates, lowering energy consumption in pumping systems. The hose's anti-kink design and high fatigue resistance translate to fewer replacements, yielding substantial cost savings over its lifecycle—often exceeding 5 years in rigorous service.
Environmental compliance is assured through low-emission materials that prevent hazardous gas permeation, aligning with REACH and RoHS regulations. Compared to rigid stainless steel lines, our flexible hose cuts installation time by up to 70%, simplifies maintenance, and enhances safety by absorbing vibrations and thermal expansion.
Furthermore, its scalability supports bespoke configurations, from micro-bore hoses for analytical instruments to large-diameter units for bulk transfers, ensuring optimal performance tailored to your operational needs.
