The utility model discloses a steam efficient heat preservation fast conveying pipeline, including conveying steel
pipe, the outer surface of conveying steel
pipe is connected with the heat preservation layer, the heat preservation layer includes
aluminium foil reflection layer, nanometer micropore heat preservation material layer,
aluminium silicate fiber blanket layer and
protection layer,
aluminium foil reflection layer's outer surface is connected with the inner wall of nanometer micropore heat preservation material layer. The device passes through the high
light reflection characteristic of
aluminium foil reflection layer, and the heat of steam is convenient for reflection to radiate outward through conveying steel
pipe, reduces the
radiation heat dissipation, passes through nanometer micropore heat preservation material layer, and there is a large number of nanometer grade micropore in its inside, and the air in micropore is restricted flow, and the
thermal conductivity coefficient of material itself is extremely low, and it is convenient to inhibit the
heat transfer outward through heat conduction greatly, utilizes
aluminium silicate fiber blanket layer and possesses the characteristics of high
temperature resistance, and the heat insulation performance is excellent, further blocks the residual heat that passes through the first two
layers and transmits, strengthens the overall
structural stability of heat preservation layer simultaneously, and then improved heat preservation effect and conveying efficiency.
