Abstract
The utility model relates to a new heat preservation pipe used for transporting the liquid. The heat preservation pipe has an inorganic rockwool layer between the alumina silicate felt layer and the aluminum foil paper layer connected on the outside of the transportation inner pipe. A polyurethane foam layer is arranged between the aluminum foil paper layer and the protecting layer, and the protecting layer is a waterproof layer made by the hard material, and the waterproof layer is the glass steel or plastic pipe.
Description
Technical field
The utility model relates to pipeline, relates in particular to the novel heat insulation pipe of the conveying high temperature fluid that needs insulation.
Background technique
At present, the pipeline of carrying high temperature fluid is incubated processing, adopts other thermal insulating materials such as in carrying, managing the inorganic rock wool of external application to do thermal insulation layer usually, twine, tie up back brush protective paint or directly do guarantor's (preventing) sheath with glass fibre cloth again with iron sheet; Add polyurethane foam again outside inorganic rock wool outside the pipe in carrying that also has or the glass wool thermal insulation layer and carry out complex heat-preservation; Add polyurethane foam again outside the calcium silicate layer that other has outside managing or glass wool carries out complex heat-preservation in carrying; Its deficiency is that heat insulation effect is poor, and the tubing volume is big, and thermal loss is big; The carbonization phenomenon of smoldering easily takes place in polyurethane foam surface of contact temperature height, causes the insulation failure.
Summary of the invention
The purpose of this utility model provides a kind of high insulating effect, and thermal loss is minimum and avoid taking place the smolder novel heat insulation pipe of phenomenon of carbonization.
The purpose of this utility model can realize by following technical measures:
The alumina silicate carpet veneer and the aluminum foil paper interlayer in this thermal insulation pipe pipe outside in being connected in conveying have inorganic rock wool layer, outside the aluminium foil ply of paper and between protective coating polyurethane foam are arranged.
The purpose of this utility model also can realize by following technical measures:
Described protective coating is meant the watertightness barrier of being made by hard material, and described watertightness barrier is meant glass fibre reinforced plastics or plastic tube.
The utility model adopts grading type heat-insulation and heat-preservation structure, the alumina silicate carpet veneer is as high temperature resistant cooling layer, inorganic rock wool layer is as temperature drop temperature layer in anti-, the aluminium foil ply of paper is as the reflecting layer, strengthen heat insulation and preservation effect, utilize the heat-insulating property of polyurethane foam, place it in outer as thermal insulating warm-keeping layer, because relatively low, guaranteed that the carbonization phenomenon of smoldering can not take place polyurethane foam through the aluminium foil ply of paper appearance temperature after the two-layer cooling.The utility model reaches structural matched well, makes this thermal insulation pipe protective coating surface temperature near natural temperature.
Description of drawings
Fig. 1 is the utility model embodiment's a schematic representation.
Embodiment
The alumina silicate carpet veneer 2 and 4 of the aluminium foil ply of papers in this thermal insulation pipe pipe 1 outside in being connected in conveying have inorganic rock wool layer 3, outside the aluminium foil ply of paper 4 and with 6 of the protective coatings that plastic tube is made polyurethane foam 5 are arranged.
Claims (4)
- Between 1, a kind of novel heat insulation pipe, the alumina silicate carpet veneer (2) that it is characterized in that being connected in pipe (1) outside in carrying and aluminium foil ply of paper (4) inorganic rock wool layer (3) is arranged, outside the aluminium foil ply of paper (4) and between protective coating (6) polyurethane foam (5) is arranged.
- 2, a kind of novel heat insulation pipe according to claim 1 is characterized in that described protective coating (6) is meant the watertightness barrier of being made by hard material.
- 3, a kind of novel heat insulation pipe according to claim 2 is characterized in that described watertightness barrier is meant glass fibre reinforced plastics.
- 4, a kind of novel heat insulation pipe according to claim 2 is characterized in that described watertightness barrier is meant plastic tube.
