| titleOfInvention | Multi-wall interlayer hollow plastic heat preserving and cold insulating pipeline |
| abstract | The invention discloses a multi-wall interlayer hollow plastic heat-insulation, cold insulation pipeline, which is composed of an inner pipe wall, a hollow pipe wall, an outer pipe wall which are connected through embedded rebars, and hollow heat-insulation layer arranged between the inner pipe wall, the hollow pipe wall and the outer pipe wall, characterized in that in the hollow heat-insulation layer, atmospheric pressure or negative pressure gases are used or heat-insulation material is filled as heat insulator; each pipe wall and the embedded rebars can be dipped, sprayed, or coated with low-emissivity mixing layer or a functional layer with low emissivity is extrudedly sticked to the inner pipe wall surface of the hollow heat-insulation layer; the outer pipe wall, the hollow pipe wall and the embedded rebars can be manufactured into rebars and walls mixed by plastics, aluminum powder and adsorption getter according to proportion; metal pipes can be embedded into the plastic inner pipe wall, linear expansion difference of which is melt by a compensator or a corrugated pipe; the cross section of the pipelines can be various shapes by using multi-wall composite pipe head extrusion processing or other molding technology; the pipeline is hot-melt by a using a hot-melt clamp, or secured by using a metal pipe outer wall nut and an inner wall nut and a connector, or uses connection method such as flange, cementation, welding or the like. |
