Thermal insulation heating and ventilation pipeline for building

The utility model relates to the technical field of buildings, in particular to a heat preservation heating and ventilation pipeline for buildings, which comprises a pipeline body, the top and the bottom of the pipeline body are fixedly connected with heat preservation layers, the heat preservation layers comprise a polypropylene fiber layer, a polystyrene fiber layer and a ceramic fiber layer, and the surface of each heat preservation layer is fixedly connected with a sound insulation layer. The sound insulation layer comprises a polyester fiber layer, a polyurethane fiber layer and a wave crest sound absorption sponge layer. Through cooperation of the pipeline body, the heat preservation layer, the polypropylene fiber layer, the polystyrene fiber layer, the ceramic fiber layer, the sound insulation layer, the polyester fiber layer, the polyurethane fiber layer and the wave crest sound absorption sponge layer, the building heat preservation heating and ventilation pipeline has the advantage of being good in
