Description

Technical Field

[0001] The utility model relates to the technical field of pipe spraying, and more specifically to a pipe inner wall spraying device. Background Art

[0002] Pipes are essential materials for construction projects, commonly used for water pipes, drainage pipes, gas pipes, heating pipes, electrical conduits, and storm drains. With the advancement of science and technology, the types of pipes used in home renovations have evolved from ordinary cast iron pipes to cement pipes (reinforced concrete pipes and asbestos cement pipes) to ductile iron pipes, galvanized steel pipes, and finally plastic pipes and aluminum-plastic composite pipes. Pipes are often coated with anti-corrosion coatings to extend their service life.

[0003] During the production process of pipelines, some dust will adhere to the inner wall of the pipeline to a greater or lesser extent. When spraying anti-corrosion coating on the inner wall of the pipeline, most of the time the dust will not be cleaned, but the anti-corrosion coating will be sprayed directly on the dust. The dust mixed in the anti-corrosion coating will reduce the adhesion of the anti-corrosion coating, which will easily cause the anti-corrosion coating to fall off, thereby affecting the anti-corrosion performance of the pipeline and reducing the service life of the pipeline.

[0004] In view of this, we propose a pipe inner wall spraying device. Utility Model Content
