LNG insulation material: aerogel insulating fabric
Thread Content
Colleagues, does anyone know anything about this insulation material? Is it currently being used for LNG?
I heard that it does exist; the LNG receiving stations in Guangdong use something like PIR plus aerogel, and the price of such products is relatively high
Aerogel insulation blankets are currently the best high-temperature insulation materials in terms of thermal insulation performance, with an insulation efficiency 3 to 4 times higher than that of traditional fiber-based insulation materials. For LNG insulation, I’ve never seen this being used; we use PIR instead
Aerogel insulation blankets are characterized by their low thermal conductivity, thin thickness required for insulation, and a wide operating temperature range that spans from -200 to up to 650°C. However, their price is currently very high; they are much more expensive than other high-end flexible insulation materials available on the market, such as AEROS from Germany and K-FLEX from Italy. Additionally, a large amount of white powder is released during installation, and it is difficult to apply these materials in areas with complex shapes such as valves.
