Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipe processing, in particular to a rock wool sealing and wrapping device for the outer wall of a directly buried thermal insulation pipe. Background Art

[0002] The development of direct burial technology for heating pipelines is inseparable from the improvement of prefabricated insulation pipe production technology. Direct buried pipelines first used foam concrete or asphalt expanded perlite as insulation materials. Foam concrete has poor water resistance and serious corrosion on the outside of the pipeline. Asphalt expanded perlite has strong water absorption, and the infiltration of water vapor will cause serious corrosion to the steel pipe. Under such circumstances, the promotion and development of direct buried pipeline technology is very slow. With the development of molecular organic synthetic material technology, prefabricated insulation pipes with high-density polyethylene shell or fiberglass shell and polyurethane foam insulation have appeared. The thermal conductivity and water absorption rate of polyurethane foam are very low, and high-density polyethylene or fiberglass have good waterproof and moisture resistance. When these insulation pipes are used for direct burial, the advantages of saving investment, small footprint, short construction period, small heat loss, long service life and small maintenance are very prominent, so that prefabricated insulation pipes will soon be used in large quantities in the direct buried pipe network of urban centralized heating. In the prefabrication process of direct buried insulation pipes, it is necessary to sandblast and polish the main body of the pipe to remove surface rust, and then wrap the rock wool around the outer wall of the pipe.
