Zusammenfassung: | The utility model relates to a composite sandwich thermal insulation pipeline, which belongs to the field of pipelines. The composite sandwich thermal insulation pipeline of the utility model solves the problem of complicated technology which is desired by traditional thermal insulation modes of pipelines and the nonideal thermal insulation effect of pipelines. A structure mode that an inner layer, an outer layer and a middle sandwich insulating layer are combined into one body is adopted by the composite sandwich thermal insulation pipeline of the utility model. The composite sandwich thermal insulation pipeline of the utility model is used for the conveying of liquids and gases, and the liquids and the gases are need to remain a certain temperature. |
