The utility model discloses a
corrosion-resistant gas conveying pipeline, which relates to the technical field of gas conveying pipelines, and comprises a
pipe body, a connecting valve, a gas inlet
pipe, a gas outlet
pipe, a gas inlet pipe, a gas outlet pipe and a gas outlet pipe, a
corrosion-resistant layer is sprayed on the inner wall of the inner pipe; the connecting pieces are detachably connected to the front end and the rear end of the pipe body and used for fixing the inner pipe into the pipe body; according to the utility model, the inner wall of the inner pipe is coated with the
corrosion-resistant layer, so that the direct contact between corrosive gas and the pipeline material is effectively isolated, the corrosion resistance of the pipeline is obviously improved, and the inner pipe is arranged, so that when the inner pipe is damaged due to long-time use or unforeseen circumstances, the corrosion resistance of the pipeline is improved, and the service life of the pipeline is prolonged. The whole pipeline
system does not need to be integrally replaced, only the damaged inner pipe needs to be independently replaced, the maintenance process is greatly simplified, gas can flow into the other pipe body by arranging the connecting valve, and therefore shutdown is not needed when the pipe body is replaced.
