Embodiment 1

[0032] The steel wire brush rust removal method inside the steel pipe of the present invention comprises the following steps:

[0033] A, make rolling wire brush, comprise the following steps;

[0034] (1) Make the rotating shaft hole frame according to the inner diameter of the pipe. see now figure 1 , figure 1 It is a schematic diagram of the structure of the rotating shaft hole frame of the embodiment of the present invention. As shown in the figure, the rotating shaft hole frame is a regular hexagonal prism round steel bracket welded by round steel. The length of the side edge 1 of the regular hexagonal prism is 150mm. The length is 50mm, and a regular hexagonal round steel bracket with the same bottom surface is inlaid inside the middle of each side edge length to increase the strength of the rotating shaft hole frame; The plane where the steel bracket is located is perpendicular to the axis of the rotating shaft. The diameter of the round steel is 10mm.

Abstract

The invention relates to a method for removing rust inside a steel pipe with steel wire brushes. The method is characterized by comprising the following steps of a, manufacturing the rolling steel wire brushes; b, providing a rotating shaft, making the rotating shaft penetrate into a steel wire brush rotating shaft hole, limiting the portion, close to the input ends, of the inner side through rotating shaft baffles, clamping the output ends through pins, and extending the rolling steel wire brushes into the metal pipe for rust removal operation. The method for removing the rust inside the steel pipe through the steel wire brushes has the advantages that the rolling steel wire brushes are simple in structure, convenient to manufacture and suitable for rust removal in various metal pipelines, operation is simple, the rust removal quality is good, the manufacturing cost of the rolling steel wire brushes is low, the steel wire brushes can be used repeatedly, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a method for removing rust inside a steel pipe, in particular to a method for removing rust with a steel wire brush inside a steel pipe. Background technique [0002] With the development of the domestic industrialization process, the technical fields such as construction industry and pipeline application have advanced by leaps and bounds. In these application fields, various types of metal pipelines are involved, and the functions of the pipelines are also diverse. As we all know, metal pipes must be derusted before use. Derusting the outer surface is relatively simple, but it is more difficult to derust the interior of the pipe. Efficient and fast removal of rust stains inside the pipeline will be the problem solving point and technological innovation point for enterprises in the application of pipeline technology. The inside and outside of DN50-DN450 metal pipes must be derusted. The known acid-base cleaning method is very ...
