As can be seen from comparison of examples 10-12 and Table 4, the corrosion rate of the pipeline is reduced to about 6% after the compound agent is added, and the pipeline is better protected.

As can be seen by comparing example 13, examples 14 to 15 and by combining Table 4, N-trimethylol methyl-2-aminoethanesulfonic acid and cinnamaldehyde further improve the cleaning effect of the detergent and the protection effect on the pipe.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
