Hot Aerogel Insulation using Pyrogel® XT-E

Aspen Aerogel’s Pyrogel® XT-E is the most effective high temperature insulation material in the industry. It has the lowest thermal conductivity of any known solid which makes Pyrogel® XT-E the leader for industrial and marine insulation. Pyrogel® XT-E are 5mm & 10mm thick blankets formed of silica aerogel and reinforced with a non-woven glass-fiber batting.

Properties

  • Extremely hydrophobic whereby it offers a high level of protection against corrosion under insulation (CUI)
  • Delivers mid to high temperature range insulation (-40⁰C to 600⁰C)
  • Extremely low thermal conductivity (k-value) that reduces heat loss
  • Light weight, thin profile and robust material

Application

Pyrogel® XT-E is ideal for insulating pipes, vessels, tanks, and equipment in a variety of industries. It is a high performing material that is durable to wear, tear and extreme weather conditions, thus it is widely accepted by many industries that include:

  • Downstream Oil and Gas Industry – Refineries, Petrochemical Plants and Gas Processing Plants
  • Upstream Oil and Gas Industry – Subsea Piping and Offshore Platforms
  • Marine and LNG Vessels
  • Power Generation Sector

Key Benefits :

The superiority of Pyrogel XT-E over existing insulation material is well defined by its performance, benefits over conventional insulation are:

  • Superior Thermal Performance
    Up to five times better high thermal performance than competing insulation products

 

  • Hydrophobic Yet Breathable
    Pyrogel® XT-E repels liquid water but allows water vapor to pass through. Thus corrosion under insulation (CUI) is significantly reduced. Hydrophobicity minimizes water ingress and breath-ability allows any trapped water to escape as vapor.

 

  • Reduced Thickness and Profile
    Equal thermal resistance at a fraction of the thickness of other industrial insulation materials. The thin profile is extremely useful in areas with space and weight constraints.

 

  • Less Time and Labor to Install
    Pyrogel® XT-E insulation is easily cut and conformed to complex shapes, tight curvatures, and spaces with restricted access.

 

  • Reusable
    Pyrogel® XT-E is easily removed for inspection and maintenance and can be reused in original service, reducing downtime and eliminating the need to purchase replacement insulation at regular maintenance cycles

 

  • Physically Robust and Impact Resistant
    Soft and flexible but with excellent spring back, Pyrogel® XT-E recovers its thermal performance even after compression events as high as 100 psi. Thus, protecting critical assets from compromise due to tool strikes, footfalls, lifting, and transportation.

 

  • Long Term Asset Integrity 
    Due to its CUI reduction capability and robust durability, Pyrogel® XT-E  gives a long term insulation solution to protect the assets in the long run.

 

  • Shipping and Warehousing Savings
    Reduced material volume, high packing density, and low scrap rates can reduce shipping volumes by a factor of five or more compared to rigid, pre-formed high-temperature insulation.

 

  • Simplified Inventory
    Unlike rigid pre-forms such as pipe cover or board, the same Pyrogel® XT-E blanket can be kitted to fit any shape or design.

 

  • Environmentally Safe
    Our high-temperature insulation is landfill disposable, shot-free, with no respirable fiber content
