Description

Wear-resistant pipe with boss

Technical Field

The utility model relates to a wear-resisting pipe, in particular to take wear-resisting pipe of boss.

Background

In modern industrial production, the transportation of many materials is involved, and pipelines are mostly used for transporting materials. The pipeline is abraded inevitably due to the flowing of materials, the abrasion of different materials to the pipeline under different working conditions is different, the pipeline is worn out in the long term, the materials leak, and the economic loss of enterprises and the environment around the pipeline are polluted. Therefore, how to effectively solve the problem of pipe abrasion is an important problem in industrial production. For this situation, most of the prior art use wear-resistant materials for lining pipes to solve the wear problem. The existing wear-resistant pipe consists of an outer sleeve steel pipe, a wear-resistant material pipe and a binder, wherein the wear-resistant material pipe and the outer sleeve steel pipe are filled with the binder to fixedly bond the wear-resistant material pipe of a lining, and the wear-resistant material pipe, the wear-resistant material pipe and the inner sleeve steel pipe are integrated to form a wear-resistant composite pipe. The single-piece length of the wear-resistant composite pipe does not exceed 12 meters generally, and a plurality of wear-resistant composite pipes are required to be connected together to form a whole wear-resistant pipeline in a long wear-resistant pipeline. In the process, whether the butt joint between the wear-resistant composite pipes is parallel and level or not and whether the central axes of the two composite pipes are on the same line or not play a vital role in the service life of the joint. In reality, the misalignment of the central axes can be affected due to the limitations of raw materials or production processes, or different installation capabilities, or the harsh installation environment, so that the central axes cannot be aligned completely. Therefore, dislocation of the central axis leads to dislocation between the two composite pipes, after the pipeline runs for a period of time, dislocation positions of the pipeline can generate material accumulation or dislocation grinding or a medium downwards along the dislocation, the binder between the wear-resistant material pipe and the outer sleeve steel pipe is impacted and worn, the binder does not have any wear resistance, the binder is quickly washed away by the medium in the pipeline, the wear-resistant material pipe is separated from the outer sleeve steel pipe, larger dislocation is generated, meanwhile, the medium can wear the outer sleeve steel pipe after the binder is washed away, the outer sleeve steel pipe can be worn in a short time, and the composite pipe cannot be used continuously after being worn, and only can be maintained or replaced. Thereby causing several serious consequences. Firstly, the leakage of the medium for wearing the pipeline destroys the surrounding environment and causes local environmental pollution. Secondly, the medium in the pipeline is blocked due to the fact that the wear-resistant material pipe falls, and the machine cannot be normally operated to cause severe production accidents such as machine halt. And thirdly, the industrial production time is wasted, and the production efficiency and the economic benefit of enterprises are reduced. Fourthly, the labor intensity of production workers and maintenance workers is increased, and the risk of safe production is increased. Fifthly, a great deal of wear-resistant materials are wasted, the material purchasing cost of enterprises is increased, and the profit of the enterprises is reduced.

SUMMERY OF THE UTILITY MODEL
