Intelligent flexible composite pipe for monitoring and repairing shaped old pipeline

Abstract

The invention discloses an intelligent flexible composite pipe for monitoring and repairing a shaped old pipeline. The intelligent flexible composite pipe has the functions of conducting monitoring in real time, conducting wireless transmission and conducting remote control. The intelligent flexible composite pipe is mainly applied to the field of fluid transportation of multiple areas like municipal administration, oil fields, industries, and ecological preservation areas. Besides, the shaped old pipeline is characterized in that in-situ repairing is conducted on an old steel pipeline which is seriously corroded and damaged, the cost of investment in replacing and renewing a large batch of new pipelines and conducting digging and excavating is avoided, the pipelines can be introduced on the basis of original old pipelines, non-excavation and non-replacement work is achieved, and the intelligent flexible composite pipe has the advantages of being high in pressure-bearing capability, high in pull-resistance, resistant to corrosion, resistant to scaling, high in flexibility, easy to curl and the like. Multiple sensors (pressure sensors, temperature sensors, flow detection sensors and the like) are embedded into the pipeline, the pipeline state can be monitored and detected in real time, information can be passed back to a receiving terminal through build-in optical fiber to be processed, and can also be transmitted to a center control unit through a GPRS, and thus integration of remote transmission and control is achieved.

Description

technical field [0001] The invention relates to the technical field of fluid transportation, in particular to an intelligent monitoring type flexible composite pipe for repairing old pipelines. Background technique [0002] After the steel pipeline has been transported for a long time, the transport medium will cause corrosion and damage to the pipeline in different scales. Due to the requirements of safe production and operation, it is necessary to excavate the original old pipeline, pull out the old pipeline, New pipeline laying, installation, welding, testing, backfilling and other multi-step and cumbersome processes also bring a great increase in cost investment. Contents of the invention [0003] In view of this, the present invention provides an intelligent monitoring type flexible composite pipe for repairing old pipelines, which can be pressed and deformed and placed in the old pipeline for repairing, with fewer steps, simple procedures and low cost. [0004] To a...
