Aerogel Insulation Blanket for Steam Pipeline Insulation Description
Superior Thermal Insulation: Aerogel felt offers 2-5 times the thermal insulation of traditional insulation materials, with a theoretical service life of nearly 20 years for high-temperature pipelines, based on experimental measurements.
Reduced Insulation Layer Thickness: Aerogel felt achieves the same thermal insulation effect with a thickness only a fraction of traditional materials. It results in minimal heat loss and high space utilization. These advantages are even more pronounced at high temperatures.
Water Repellency and Fire Resistance: Aerogel felt effectively prevents moisture from entering pipes and equipment. It also boasts Class A fire resistance, and its unique three-dimensional network structure prevents the significant decrease in insulation performance caused by sintering, deformation, and settling that occur with other insulation materials during long-term high-temperature use.
Convenient Installation: Aerogel felt is lightweight and easy to cut and sew to fit various pipe and equipment shapes, requiring less installation time and manpower.
Reduced Transportation Costs: The smaller package size and lighter weight significantly reduce the transportation costs of insulation materials.
The core material of aerogel insulation blankets is silica aerogel. Aerogel is a nanoporous solid with pore sizes typically between 10 and 50 nm, filled with still air.
Its insulation mechanism mainly includes:
● Inhibiting heat conduction: The nanoscale pores significantly reduce the heat conduction path between the solid framework and the gas.
● Inhibiting convection: The pore size is much smaller than the mean free path of air molecules, preventing effective air convection.
● Reducing thermal radiation: Radiative heat transfer at high temperatures is reduced by adding infrared shielding agents (such as carbon black and TiO₂).

FAQ
1. What is an aerogel blanket?
An aerogel blanket is a flexible thermal insulation material made by embedding nanoporous aerogel particles into a fiber matrix (e.g., glass fiber), producing a lightweight, soft insulation blanket.
2. What is aerogel?
Aerogel is a highly porous, lightweight solid where the liquid part of a gel is replaced by gas, resulting in extremely low thermal conductivity.
3. How does an aerogel blanket insulate?
The nanoporous structure traps air and dramatically reduces heat transfer (by conduction and convection), giving much lower thermal conductivity than traditional insulation.
4. Typical thermal performance?
Aerogel blankets often have very low thermal conductivity (often around 0.015–0.022 W/m·K at ambient conditions), allowing thin insulation layers to perform as well or better than thicker conventional insulation.
