Insulon Vacuum Jacketed High Pressure Hose with MLI

Product Description

The Insulon Vacuum Jacketed High Pressure Hose with MLI (multi-layered insulation) is engineered with a proprietary, high-density form of multi-layer insulation to achieve unparalleled thermal insulation performance, even in high-temperature applications. The multi-layer insulation (MLI) effectively minimizes radiation heat transfer through layers of reflective materials. This advanced technology makes the hose suitable for a wide range of applications, including gas or liquid transfer in both cryogenic and high-temperature environments. The MLI jacketed design enhances the overall insulation efficiency, providing a highly effective solution for maintaining the integrity of gases or liquids during transportation or storage.

Applications

• Aerospace,
• Automotive,
• Cable & Wire Harnesses,
• Chemical Processing,
• Cleanroom Manufacturing,
• Cryogenic Fluid Transfer,

• Cryotherapy Devices,
• Food-Grade Applications,
• Fuel & Oil Lines.

Features

• Compatible with cryogenic fluids including hydrogen, LN2, many others,
• Durable, reliable construction using cleanroom-compatible materials (316L stainless steel) make these hoses easy to install, clean and sterilize, and will reduce the risk of corrosion-under-insulation (CUI), 
• Low spring back reduces stress on connections and joints,
• Naturally flame-retardant, non-fibrous materials for maximum safety in use. 
• Various end connections to reduce condensation, dripping, and risk of mold,
• Reduce cryogenic material losses due to boil-off,
• Multi-layer insulation (MLI) maintains a safer external surface temperature to minimize heat transfer to improve thermal energy efficiency.

Specifications

• Thermal Range:  -270°C to 900°C (-454°F to 1652°F),
• Jacket material:  316L Stainless Steel,

• Stainless steel Tube Stub,

• Pressure tests are conducted at 1.5x MAWP according to NAHAD Corrugated Metal Hose Assembly Specification Guidelines, p. 33 (2005).

• Insulation “touch temperature” performance for 6ft Length Hose:

• Cryogenic Performance:  For LN2 (at -196°C) the hose jacket temperature was over 9°C, for temperature difference (∆T) of >205°C (369°F) warmer.  

 

• High Temperature Performance:  For hot air (at 900°C (1652°F) the hose jacket temperature maintained under 260°C (482°F), for temperature difference (∆T) of >205°C (369°F) cooler.  

• This chart illustrates the difference between the media temperature (hot air) and the outer surface temperature (aka “touch temperature”). When the process media was 900°C (1652°F), the temperature difference was over 640°C (1150°F) at steady state.

• Insulation Reliability with Thermal Cycling: 

• >20,000 cycles at 450°C with no degradation in insulation performance. (Cycles were 3-minute ramp up from 23°C ambient temperature to reach steady-state, followed by a 2-minute cool-down period.
