Traceable pipeline

[0002] The tracer pipeline is an indispensable pipe material in the current social construction. It prevents the direction of the pipeline from being unknown after the pipeline is laid, and increases the maintenance cost in the later stage; while the existing tracer pipeline is to bury a metal wire in the pipeline, The pipe thus realized can be detected to achieve the purpose of tracing, and the expansion coefficients of the metal wire and the plastic are different, resulting in poor compatibility of the two materials, making it difficult to integrate the pipe and the metal wire; and the metal wire It is easy to be corroded, especially in a humid environment, and most of the pipelines are buried in the wet underground; when the pipeline is buried for a long time, the metal wire will also be corroded, which will cause the pipe to be untraceable

[0003] In addition, in the production process of the existing tr...

Beneficial effect of the present invention: by magnetic powder is put into non-magnetic color mark machine with co-extrusion extruder extruding on the outer wall of pipeline body under hot-melt state by magnetic powder with materials such as carrier resin as carrier, form tracer line, This makes the pipeline detectable; it solves the problem of complex process and waste of materials caused by setting metal lines in the pipeline through a special process in order to make the pipeline detectable and traceable in the prior art; it solves the problem of metal wire The expansion coefficient of the plastic is different, which leads to poor compatibility of the two materials, so that it is difficult to integrate the pipe and the metal wire; it solves the problem that the metal wire is easily corroded in the prior art, especially when it is wet In an environment where the pipeline is buried for a long time, the metal wire will be corroded, which will lead to the pro...
