The characteristics of aerogel felts used for pipeline insulation

Excellent thermal insulation performance

• Ultra-low thermal conductivity: Aerogel felts are one of the solid materials with the lowest known thermal conductivity. Their nanoscale pore structure can effectively inhibit heat transfer, and the thermal conductivity can be as low as 0.013 - 0.018 W/(m·K). Compared with traditional thermal insulation materials such as rock wool and glass wool, under the same thermal insulation effect, the thickness of aerogel felts can be greatly reduced. For example, in some high-temperature pipeline insulation scenarios, only a few millimeters of aerogel felts may be needed to achieve the same thermal insulation effect that would require several centimeters of traditional thermal insulation materials.

• Effectively reduce heat loss: It can significantly reduce the heat loss of media (such as steam, hot water, hot oil, etc.) in pipelines during transportation and improve energy utilization efficiency. For the thermal pipeline systems in industrial production, after using aerogel felts for insulation, the heat loss can be reduced by about 30% - 50%, which helps to reduce energy costs and carbon emissions.

Good fireproof performance

• High temperature resistance and non-flammability: Aerogel felts are Class A non-combustible materials and can withstand high-temperature environments. They can maintain stable physical and chemical properties at temperatures as high as 650 °C - 1000 °C (slightly different depending on the composition and process), will not burn, and will not produce toxic and harmful gases. This is extremely important for the insulation of pipelines transporting high-temperature media or in places with high fire safety requirements (such as the petroleum, chemical, and power industries).

• Prevent the spread of flames: In the event of a fire, aerogel felts can play a role in blocking the spread of flames, buying time for personnel evacuation and fire fighting, and reducing the damage to the pipeline system and surrounding facilities caused by the fire.

Light and thin physical characteristics

• Low density: The density of aerogel felts is usually relatively small, generally between 180 - 300 kg/m³, which is much lighter than traditional thermal insulation materials. This makes it easier to operate and install during the pipeline insulation construction process, reducing the load-bearing burden of the pipeline. It is especially suitable for pipeline systems that are sensitive to weight, such as pipelines erected at high altitudes or those with restrictions on structural loads.

• Thin design: It is thin and can achieve good thermal insulation effects without taking up too much space. For pipeline layout environments with limited space, such as the dense pipeline areas in buildings or the pipeline systems inside equipment, the thin advantage of aerogel felts can be fully demonstrated, and the normal operation or installation of other components will not be affected due to the excessive thickness of the insulation layer.

Waterproof and moisture-proof performance

• Strong hydrophobicity: Aerogel felts have good hydrophobic properties, and their surfaces are not easily wetted by water. In humid environments or when condensation may occur on pipelines, they can effectively prevent moisture from entering the interior of the insulation layer, avoiding problems such as the decline in thermal insulation performance and material corrosion caused by moisture accumulation. For example, in the insulation of refrigerant pipelines in air-conditioning systems, aerogel felts can prevent condensate from damaging the insulation layer.

• Good humidity stability: Under different humidity conditions, the thermal insulation performance and physical properties of aerogel felts remain basically stable, and phenomena such as pulverization and deformation will not occur due to humidity changes, ensuring a long-term and stable thermal insulation effect.

Environmental protection characteristics

• Non-toxic and harmless: The components of aerogel felts generally do not contain toxic and harmful substances, causing less harm to the environment and human health during production, use, and disposal.

• Potential for recyclability: Some aerogel felts may have the potential for recycling through appropriate processes after their service life ends, which conforms to the concept of sustainable development.
