Abstract

The invention provides a pipe, a preparation method of the pipe and a concrete machine. The pipe includes: a pipe body; a wear-resistant coating formed on the inner wall of the pipe body by thermal spraying; wherein the wear-resistant coating includes a ceramic material coating. The wear-resistant coating can prevent the material from directly impacting and wearing the pipe body, thereby preventing the pipe body from being abraded by the material and prolonging the service life of the pipe body. weight and production costs. The wear-resistant coating is an integral structure formed by thermal spraying. On the one hand, the structural stability of the integral structure is strong, and there is no structural connection section, which can effectively avoid structural damage or shedding. On the other hand, thermal spraying technology has the ability to form The advantages of high efficiency and strong stability can reduce the production cost of the pipeline and further improve the structural stability of the wear-resistant coating.

Description

technical field

[0001] The invention relates to the technical field of engineering machinery, in particular to a pipeline, a method for preparing the pipeline and a concrete machine. Background technique

[0002] In the current concrete pipeline, the inner layer of the double-layer pipe body is made of wear-resistant metal to reduce the abrasion of the concrete on the pipeline. However, the inner layer of the pipe is made of wear-resistant alloy, which has the problems of heavy weight and low service life.

[0003] Therefore, how to design a conveying pipeline with lighter weight and stronger wear-resisting life has become a technical problem to be solved urgently. Contents of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, a first aspect of the invention provides a pipeline.

[0006] A second aspect of the present invention provides a method for preparing a ...
