Tile prefabricating heat preservation pipeline with dampproof device

Abstract

The invention relates to a tile prefabricating heat preservation pipeline with a dampproof device. The tile prefabricating heat preservation pipeline comprises a work pipe layer, a heat preservation layer, a dampproof layer and an outer sheath layer. The work pipe layer is a work steel pipe. The heat preservation layer is a calcium metasilicate tile. The dampproof layer comprises a waterproof cold sizing material layer, an aluminum foil adhesive tape layer and a graphene dampproof coating, wherein the outer surface of the work steel pipe is directly coated with the waterproof cold sizing material layer, the aluminum foil adhesive tape layer is wound around the outer surface of the calcium metasilicate tile, and the outer surface of the aluminum foil adhesive tape layer is coated with the graphene dampproof coating. The outer sheath layer is an iron sheet layer, and the outer surface of the iron sheet layer is coated with an anti-corrosion coating layer. By means of the tile prefabricating heat preservation pipeline, multiple dampproof protection can be conducted on the heat preservation pipeline, the dampproof performance of the heat preservation pipeline is effectively improved, the dampproof coating is modified through high softness and strong corrosion resistance of grahene, the service life of the dampproof coating is prolonged, and the service life of the heat preservation pipeline is prolonged accordingly.

Problems solved by technology

[0002] In urban municipal engineering, heating pipes and domestic water supply pipes are directly buried underground, which not only makes full use of the underground space, but also effectively saves the space above the ground and regulates the use of the space above the ground; however, the heating The pipes and water supply pipes are directly buried in the ground, and the underground environment is relatively humid. Without effective moisture-proof measures for the insulation pipes, the insulation pipes are easily damaged by moisture. If the insulation layer is damaged, the insulation effect of the insulation pipes will be affected. It is easy to cause heat loss during the process; when the insulation layer is seriously damaged, the working tube will be corroded, and the compressive mechanical properties of the working tube will be reduced. As time goes by, the pipeline will leak, which will affect the transportation of liquid, and even Affect urban road safety

[0003] Although there are certain moisture-proof and anti-corrosion measures in the current thermal insulation pipelines, these moisture-proof measures are too simple, and the effective time of moisture-proof protection is short. It is damaged by corrosion, which affects the insulation and transportation performance; moreover, the moisture-proof material of the current insulation pipeline is poor in flexibility, and the moisture-proof layer is easy to crack, which in turn gradually affects the insulation and transportation performance, greatly reducing the service life of the insulation pipeline
