Corrosion-resistant anti-aging MPP electric power pipe with self-repairing function

Abstract

The invention relates to the technical field of power pipelines, in particular to a corrosion-resistant anti-aging MPP power pipe with a self-repairing function, which comprises a pipeline main body and an isolating layer, the pipeline main body is a modified polypropylene layer, and the inner side of the modified polypropylene layer is sequentially connected with a lining layer and an insulating coating; an outer lining layer, a reinforcing layer and an anti-corrosion coating are sequentially connected to the outer side of the modified polypropylene layer, an inner repairing ring is fixedly installed in the pipeline body, a pipeline self-repairing structure with a vibration sensing function is installed in the inner repairing ring, and a check ring is fixedly connected to the pipeline body. The isolating layer is fixedly connected with an isolating layer self-repairing structure with a heat sensing function; and according to the MPP electric power pipe, the structural level improvement of the single-material MPP electric power pipe is carried out, the pipeline self-repairing structure and the isolation layer self-repairing structure are arranged at the connecting end of the pipeline, the problem of pipeline aging corrosion is solved in time, and the service life of the electric power pipe is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric power pipes, in particular to a corrosion-resistant and anti-aging MPP electric power pipe with self-repairing function. Background technique [0002] With the development of my country's economy, the construction of infrastructure is getting faster and faster, and among these infrastructures, the laying of power pipelines is undoubtedly very important. At present, most power pipeline systems use MPP power pipes as the main component. MPP power pipes use modified polypropylene as the main raw material, which does not require a lot of dredging, digging and damaging the road surface. It is used in special areas such as roads, railways, buildings, and riverbeds. It is widely used in construction projects such as laying pipelines and cables. MPP power pipe has the characteristics of high temperature resistance and external pressure resistance. [0003] However, the current MPP power pipes have poor...

AI Technical Summary

Problems solved by technology

[0003] However, the current MPP power pipes have poor corrosion resistance and anti-aging performance, and because two pipes generally need to be connected to form a pipe of the required length during use, the connection between the two pipes is generally prone to strength defects. It is more susceptible to erosion by the external environment, causing damage to the power tube, and the safety of the cables in the power tube is difficult to guarantee
