Research on Joint Insulation Technology of Super-Long Large-Diameter Heat Supply Pipeline
As the aorta of clean heat source supply,urban heating network plays an extremely important role.Rely-ing on a heating pipeline network project,a thermal insulation joint system adapted to different underground rivers was developed to address the varying levels of groundwater encountered during the installation of long-distance heating pipelines.By changing the different bonding methods of the heat shrinkable belt,the heat preservation ef-fect reaches the standard and the corrosion resistance of the heating pipe is improved.Aiming at the pipeline tem-perature stress caused by the temperature change of its internal liquid and the temperature change of the external en-vironment,a direct buried heating pipeline insulation structure with good insulation effect,strong ductility and re-covery performance was developed.
