A cryogenic hose is a highly specialized flexible hose designed for the safe transfer of extremely low-temperature liquids and gases. These hoses are widely used in industries that handle liquefied gases such as LNG (liquefied natural gas), liquid nitrogen, liquid oxygen, liquid helium, liquid hydrogen, and liquid argon.
Key Features
• Temperature Resistance: Typically rated down to –196°C (–321°F) or even lower.
• Construction:
• Inner Tube: Stainless steel corrugated tube or PTFE (depending on application).
• Reinforcement: Braided stainless steel or multiple plies for strength.
• Outer Cover: Insulated layers or protective braiding.
• Flexibility: Designed to remain flexible even at cryogenic temperatures.
• Safety: Built to prevent leaks, frost damage, and pressure loss.
Applications
• Loading/unloading LNG from ships, trucks, and tanks.
• Medical and laboratory use for liquid nitrogen and oxygen transfer.
• Aerospace industry for rocket fuel transfer (liquid hydrogen, liquid oxygen).
• Food and beverage industry (cryogenic freezing with liquid nitrogen).

Pressure Range
• Usually low to medium working pressures (10–40 bar common for LNG hoses).
• Some designs can handle higher depending on construction.
