Description

Technical Field

[0001] The utility model relates to the field of thermal insulation pipes, and in particular to a device for wiping the outer wall of a steel pipe after rust removal. Background Art

[0002] When making insulation pipes, the surface of the steel pipe must be derusted first. Rust removal is usually done by shot blasting machines. After shot blasting, a small amount of dust and fine particles will remain on the surface of the steel pipe. It may be necessary to wipe it to ensure that the surface is absolutely clean. Usually, dust and fine particles are not allowed to remain on the surface of the steel pipe when making insulation pipes.

[0003] The presence of dust and fine particles may have the following adverse effects: First, they may affect the bonding effect between the insulation material and the steel pipe surface, resulting in a loose bond between the insulation layer and the steel pipe, thereby reducing the insulation performance. Second, these impurities may form tiny corrosion spots on the surface of the steel pipe, which will accelerate the corrosion of the steel pipe over time and shorten its service life. In addition, impurities may also cause friction damage during construction and use, destroying the overall structure of the insulation pipe.

[0004] Therefore, in order to ensure the quality and performance of the insulation pipe, the surface of the steel pipe should be kept as clean as possible to avoid the presence of dust and fine particles. Utility Model Content
