Beschreibung
Zusammenfassung:	The utility model discloses a pipeline heat preservation assembly which comprises a pipeline, a first heat preservation layer and a second heat preservation layer. The first heat preservation layer comprises a plurality of first heat preservation sections which are sequentially laid in the axial direction of the pipeline, the first heat preservation sections are circumferentially wound on the outer wall of the pipeline, the head ends and the tail ends of the first heat preservation sections are attached to form first axial lap joint parts, and the adjacent first axial lap joint parts are not collinear; the second heat preservation layer comprises a plurality of second heat preservation sections which are sequentially laid in the axial direction of the pipeline, the second heat preservationsections are circumferentially arranged on the first heat preservation layer in a winding mode, the head ends and the tail ends of the second heat preservation sections are attached to form second axial lap joint parts, and
