Embodiment 1
[0029] Embodiment one: as attached Figures 1 to 8As shown, the soft-hard combined prefabricated steam overhead thermal insulation pipe includes a thermal insulation pipe body and a bracket body. A soft cushion layer 2, a thermal insulation support layer and an outer protective pipe 11 are sequentially provided from the inside to the outside. The thermal insulation support layer includes a soft thermal insulation layer and a hard support layer. The supporting layer, each hard supporting layer includes at least two layers of hard layers 4 distributed sequentially from the inside to the outside, and the outer side of the soft cushion layer 2 corresponding to the position between every two adjacent hard supporting layers is provided with a soft Insulation layer, each soft insulation layer includes at least two layers of soft layers 5 distributed sequentially from the inside to the outside; at least one group of adjacent soft insulation layers is provided with a bracket body on th...
Embodiment 2
[0031] Embodiment two: as attached image 3 , 4 , 5, also includes a fixed layer 7, a fixed layer 7 is provided between the outer protective tube 11 and the hard support layer, and at least one injection hole 8 is provided on the outer side of the outer protective tube 11 corresponding to each fixed layer 7 position; The material of the fixing layer 7 is polyurethane foam material or phenolic resin foam material. During use, polyurethane foaming material is injected between the outer protection tube 11 and the hard support layer through the injection hole 8 to foam the aldehyde resin. During use, polyurethane foam material is injected between the outer protective tube 11 and the hard support layer through the injection hole 8, and the space between the outer protective tube 11 and the heat-insulating support layer is reinforced.
Embodiment 3
[0032] Embodiment three: as attached Image 6 , 7 , 8, it also includes an isolation layer 9, a filling layer 10 and a fixing belt, and an isolation layer 9 and a filling layer 10 are sequentially arranged between the outer protective tube 11 and the heat preservation support layer from inside to outside, corresponding to each hard support layer The outside of the isolation layer 9 at the position is bound with a fixing belt; the isolation layer 9 is aluminum foil or nano-airbag reflective layer 6, and the material of the filling layer 10 is polyurethane foam material or phenolic resin foam material. During use, by setting the isolation layer 9, not only the better heat insulation and heat preservation effect between the outer protective tube 11 and the heat preservation support layer can be achieved, but also the polyurethane foam material can be prevented from extruding the soft heat insulation layer; Layer 10, the aldehyde resin foam material. During use, polyurethane foa...
