Description

technical field

[0001] The invention relates to a rust removal device, more particularly to a rust removal device for the inner wall of a pipeline, and belongs to the technical field of rust removal and polishing equipment. Background technique

[0002] With the development of industrialization, the development of technical fields such as construction industry and pipeline transportation is advancing by leaps and bounds. In these application fields, a large number of steel pipes of different diameters and lengths are involved and used.

[0003] Among them, in addition to the factors of design, production and installation, the service life of buildings using steel structures and various pipelines has a significant causal relationship with the rust removal and anti-corrosion engineering of steel structure materials; in addition, rust removal of steel is more important. It is the key point of coating and anti-corrosion engineering. It is also for this reason that the rust remo...
