Aerogel insulation board, as a cutting-edge insulation material based on nano-porous structure, not only performs exceptionally well in low-temperature cold preservation, but also demonstrates unique technical value in high-temperature industrial pipeline insulation. With its extremely low thermal conductivity, excellent heat resistance, and outstanding structural flexibility, aerogel insulation board is gradually becoming the preferred alternative to traditional insulation materials in high-energy-consuming industries such as chemical, power, and thermal power. 
I. Core Advantages of Aerogel Sheets in High-Temperature Applications 
Stable adiabatic performance under high temperatures 
The nanoscale network structure of the aerogel blanket can effectively inhibit heat conduction and thermal radiation. Even under high-temperature conditions (with the maximum long-term usage temperature reaching up to 650℃), its thermal conductivity can still remain at 0.020–0.026 W/(m·K), which is significantly lower than that of traditional high-temperature insulation materials, and the insulation efficiency has been significantly improved. 
2. Ultra-thin design saves space 
Under the same thermal resistance requirements, the thickness of the aerogel毡 is only 1/2 - 1/3 of that of traditional ceramic fibers or rock wool materials. It is particularly suitable for pipe galleries， equipment interlayers and renovation projects with dense pipelines and limited installation space， and can effectively optimize the pipeline layout. 
3. Flexible and capable of adapting to complex structures 
The material has excellent flexibility and tensile strength, and can closely cover irregular parts such as elbows, valves, and pump bodies, achieving uninterrupted insulation. It reduces heat loss caused by seams or gaps, and is easy to install, significantly reducing the difficulty of on-site installation. 
II. Main Application Industries and Scenarios 
- Petrochemical industry: Reactor outlet pipelines, high-temperature cracking pipelines, heat transfer oil system 
- In the field of power energy: steam transportation pipelines, waste heat recovery systems, gas turbine pipelines 
- Thermal supply system: Urban heat network pipelines, industrial heating pipelines 
Pharmaceutical and food engineering: High-temperature clean pipelines, sterilization equipment lines 
- Other industrial applications: High-temperature flue gas pipelines in metallurgy, Hot air pipelines in the building materials industry 
III. Key Precautions for Construction 
System integration and security design 
It is recommended to use stainless steel straps or high-temperature binding tapes for fixation, and add metal protective shells such as aluminum foil and stainless steel plates on the outer layer to enhance mechanical protection and durability. The joints of the protective shells should be sealed to prevent water vapor from entering. 
2. Multi-layer Laying and Joining Technology 
During multi-layer construction, the aerogel mats of each layer should be laid with staggered joints. The overlap width should be no less than 100mm. Sealing at the joints can be done using high-temperature adhesive tape or the special adhesive for aerogel to prevent the formation of thermal bridges. 
3. Moisture-proof storage and construction environment control 
During storage and construction, the material should be kept dry to avoid being exposed to rain or prolonged exposure to high humidity. Before installation, it is necessary to ensure that the surface of the pipeline is clean and free of oil stains and rust. 
4. Strengthening of detailed nodes 
For areas prone to thermal bridges such as flanges and supports, it is recommended to use aerogel composite prefabricated components or to fill in aerogel shredded insulation on-site for enhanced insulation, ensuring the overall insulation continuity of the system. 
IV. Summary
The aerogel insulation blanket, with its comprehensive advantages of "high-efficiency insulation, ultra-thin and lightweight, flexible and temperature-resistant", provides a solution for industrial high-temperature pipeline insulation that combines energy-saving benefits and space optimization value. Although the initial investment is relatively high, its long-term value in reducing heat loss, improving system energy efficiency, extending service life, and reducing maintenance costs is increasingly evident. With the continuous enhancement of industrial energy-saving requirements under the "carbon neutrality" goal and the cost optimization brought about by the large-scale production of aerogel, the application of this material in the field of high-temperature industrial insulation will further expand, providing key technical support for the green transformation of the industry.
