Description

Technical Field

[0002] Steel pipes are indispensable turnover materials in construction projects. They are not only used in large quantities, but also frequently erected and dismantled. After the steel pipes are erected, they are exposed to the sun and rain for a long time, and are subjected to load impact. Therefore, it is easy for the surface paint to fall off and rust to occur. After disassembly, rust removal and anti-corrosion maintenance work are required, so steel pipe rust removal equipment is needed.

For example, during the rust removal process, the above patent fixes the steel pipe by the fixing cylinder, which will cause the part of the steel pipe located inside the fixing cylinder to be unable to be rusted, resulting in the appearance of an un-rusted area.
