[0002] Aerogel felt is a flexible thermal insulation felt made of nano-silicon dioxide or metal aerogel as the main material, which is compounded with carbon fiber or ceramic glass fiber wool or pre-oxidized fiber felt through a special process. It is characterized by low thermal conductivity, certain tensile and compressive strength, and strong corrosion resistance. It is a new type of pipeline insulation material.

[0003] When using aerogel felt sheets in the prior art, the aerogel felt sheets need to be wrapped around the outer wall of the pipe and then locked by a tightening ring, which has the following disadvantages:
