Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a double-layer thermal insulation aluminum-plastic pipe. Background Art

[0002] Aluminum-plastic pipe is a new type of pipe made of a middle layer of longitudinally welded aluminum pipe, inner and outer layers of polyethylene plastic, and hot melt adhesive between layers. Polyethylene is a non-toxic, odorless plastic with good impact resistance, corrosion resistance, and weather resistance; the middle layer of longitudinally welded aluminum pipe gives the aluminum-plastic pipe the compressive strength and impact resistance of metal, making it easy to bend without rebounding. Aluminum-plastic pipe has two major characteristics: the strong pressure resistance of metal pipes and the acid and alkali resistance and corrosion resistance of plastic pipes. Due to its light weight, durability, convenient construction, and bendability, it is more suitable for use in home decoration.

[0003] When laying aluminum-plastic pipes, insulation pipes are usually installed around the aluminum-plastic pipes to achieve double-layer insulation. However, if the insulation pipe is directly inserted on the aluminum-plastic pipe, if the insertion length is too long, the friction during the insertion process is large, which ultimately leads to the problem of inconvenience in installation.
