Understanding Vacuum-Jacketed Hoses

Aero-Flex Corp. excels in the manufacturing of vacuum-jacketed hoses and piping, a specialized innovation that revolutionizes the transportation of cryogenic liquids. These high-performance solutions are designed to minimize heat transfer and maintain the ultra-low temperatures required for the safe and efficient transfer of liquefied gases. The unique construction of vacuum-jacketed flex hoses consists of an inner and outer stainless steel hose or pipe, with the space between them evacuated to create a vacuum layer. This vacuum layer acts as a thermal insulator, significantly reducing heat transfer by conduction and convection.

Our Unique Construction

The unique construction of vacuum-jacketed flex hoses embodies innovation and functionality. It consists of:

  • Inner Stainless Steel Hose/Pipe: This inner conduit is the primary carrier of the cryogenic liquid. Made of specialized stainless steel, it is designed to withstand extreme temperatures without losing integrity or performance.

  • Outer Stainless Steel Hose/Pipe: Surrounding the inner pipe, the outer stainless steel pipe serves as a protective layer. This construction adds durability and resistance against environmental factors, such as temperature fluctuations, physical damage, or corrosive conditions.

  • Vacuum Layer: Between the inner and outer pipes is a space that has been carefully evacuated to create a vacuum layer. This absence of air acts as a thermal insulator, significantly reducing heat transfer by conduction and convection.

  • Additional Insulating Materials: In some configurations, additional layers of insulating material may be used to further enhance the insulating properties of the vacuum jacket from UV. This can include materials known for their high thermal resistance like aluminized mylar, which complements the vacuum layer by reflecting the UV that may enter the hose so that it doesn’t affect the the temperature of the the cryogenic liquid inside. .

Thermal Insulation: An In-Depth Look

The vacuum layer’s function as a thermal insulator is a core aspect of the technology. By creating a vacuum, the molecules responsible for transmitting heat through conduction and convection are virtually eliminated. This results in an environment where thermal energy has difficulty moving from the warm exterior to the cold interior, thus preserving the cryogenic liquid’s temperature. As an added layer of protection, aluminized Mylar is wrapped around the inner hose at a specific amount of wraps. This will help scatter the UV that enters the hoses outer layer. This additional layer of protection along with the vacuum assures the ectremely cold cryogenic liquid flowing through the inner hose is not affected in any way.

This sophisticated approach to insulation provides significant advantages over traditional methods, offering a higher level of efficiency in maintaining temperature, reduced energy consumption, and an extended lifespan for the equipment.
