The invention provides a pipeline pulse cleaning technology. A metal sheet is arranged on the inner side of a bend channel of a pipeline to be cleaned. The technology concretely comprises the following steps of mixing non-newtonian liquid magnetic particles and a first cleaning fluid to form a mixed cleaning fluid; washing a fixed cleaning mixed fluid into the pipeline to be cleaned by utilizing high-pressure gas pulse, and introducing ultrasonic waves into the pipeline to be cleaned; inputting a second cleaning fluid with the temperature being 70-100 DEG C into the pipeline to be cleaned forsoaking; and inputting high-pressure aqueous vapor into the pipeline to be cleaned for washing. By adopting the pipeline pulse cleaning technology provided by the invention, through combined action ofhigh-pressure gas pulse, the non-newtonian liquid magnetic particles and the metal sheet, the problem of poor bend channel cleaning effect when the pipeline is cleaned is solved.
