Essential components and spare parts for cryogenic equipment include vacuum-insulated piping, flexible metal hoses, specialized valves (long/short stem), phase separators, and liquid level controllers, ensuring safe storage and transport of liquids below -73C. Key spares feature bayonet assemblies, solenoid valves, pressure gauges, and cryogenic seal materials like indium, catering to industries from LNG to medical research.
Common Cryogenic Components and Spare Parts
- Transfer and Piping: Vacuum Insulated Pipe (VIP) and flexible metal hose assemblies.
- Valves and Controllers: Cryogenic valves, solenoid valves, safety relief valves, check valves, and phase separators.
- Storage and Safety: Liquid nitrogen/helium dewars, storage tank parts, and pressure gauges.
- Seals and Connections: Indium wire/solder preforms, bayonet assemblies (Linde/Cryolab style).
- Support Hardware: Insulation materials, pump-out operators, and fill stations.
Cryogenic Equipment Maintenance & Safety
- Replacement Parts: High-pressure exhaust blowers and insulated copper pipes are used for cryogenic freezer maintenance.
- Safety Equipment: Protective gloves, face shields, and proper clothing are critical to avoid frostbite or asphyxiation during transfer.
- Specialized Parts: Rotors and pins for cryogenic grinding/milling systems
