Gas pipeline through-wall anti-corrosion jacket

A gas pipeline through-wall anti-corrosion jacket is used for preventing corrosion of a pipeline and comprises a jacket body arranged on the pipeline in a sleeving mode, a containing cavity is formed between the inner wall of the jacket body and the outer wall of the pipeline, and the containing cavity is filled with a viscoelastic body. According to the embodiment of the utility model, the viscoelastic body is used as an anti-corrosion material and is filled in the accommodating cavity between the sleeve body and the pipeline, and the sleeve body tightly holds the filled viscoelastic body material, so that the viscoelastic body material is tightly coated on the pipeline and does not fall off due to collision or scratch, and the viscoelastic body material can be fully distributed at each position on the pipeline through the flowing property and the viscosity of the viscoelastic body, so that the pipeline is prevented from being damaged. The reinforced anti-corrosion pipe section is difficult to break away fro
