The utility model relates to an energy saving casing for pipelines, which is the improvement of a pipeline structure for connecting pipelines. The inner layer of a metallic outer pipe is provided with an intermediate pipe made of plastic, and the inner layer of the intermediate pipe is provided with a metallic inner pipe. The both ends of the metallic outer pipe are provided with external screws used to be connected in the pipeline. The energy saving casing for pipelines reduces the medium flow in the casing for pipelines and the heat transfer outside the casing for pipelines. The utility model reduces the energy loss, improves the heat efficiency, prevents the leakage of the power and is suitable for popularization and use in the pipeline connection.
