Description

Technical Field

[0001] The invention belongs to the technical field of steel pipe cleaning, and in particular relates to a steel pipe outer surface cleaning device. Background Art

[0002] In the process of building construction, steel pipes are important building materials and are widely used in supports, steel structures and other functional components. However, after the steel pipes are used in construction, their outer walls are often attached with oil stains, paint, etc., which not only affects the appearance of the steel pipes, but also may have adverse effects on their subsequent use and maintenance. Therefore, effective cleaning of the outer wall of the steel pipe is an important part of the subsequent construction work.

[0003] At present, there are equipment and methods for cleaning the outer wall of steel pipes on the market, including mechanical cleaning, chemical cleaning and manual cleaning. Mechanical cleaning devices usually use brushes, grinding wheels or sandblasting to remove dirt, but the efficiency and effectiveness of mechanical devices may be limited when dealing with large steel pipes. Manual cleaning is labor-intensive, inefficient and difficult to ensure the consistency of cleaning. The chemical cleaning method dissolves dirt through chemical agents and sprays the agents directly on the outer wall of the steel pipe. Cleaning the surface of the steel pipe with chemicals can effectively avoid the problems of mechanical cleaning and manual cleaning. However, there is chemical residue on the surface of the steel pipe after cleaning with chemicals, which affects the service life of the steel pipe in the later period. Summary of the invention
