Abstract
The invention relates to the technical field of gas pipelines, in particular to a double-layer PE gas pipe with a termite-proof protective layer. The double-layer PE gas pipe comprises a gas pipeline which is of a double-layer structure formed by an inner layer used as a conveying pipe and an outer protective layer capable of preventing corrosion by termites. A bonding layer is arranged on the connection portion of the inner layer and the outer protective layer. The outer protective layer can be separated from the inner layer with the bonding layer under the effect of external force in a peeling mode. Certain bonding force exists between the inner layer and the outer protective layer, the fact that the two layers can be bound tightly and cannot slide or be separated is guaranteed, and meanwhile during a mounting process, the outer protective layer on a needed portion can be separated in a peeling mode through external force, a conveying pipe of the inner layer cannot be damaged, compared with a single-layer PE gas pipe, the double-layer PE gas pipe has the advantages that a termite-proof function is achieved, scratching is prevented, connecting is safe and convenient, and safety and reliability of using and mounting of the gas pipe can be effectively improved.
