The embodiment of the invention provides a cathode protection pipe section extraction method and device. The method comprises the following steps: establishing a cathode protection logic diagram of atarget pipeline; extracting a cathode protection pipe section along the cathode protection logic diagram based on an extraction starting point, wherein the extraction starting point comprises a firstextraction starting point, and the first extraction starting point is a potentiostat in the cathode protection logic diagram; and generating a logic management subsection diagram of a target pipelinecathode protection system according to the extracted cathode protection pipe section. The method can achieve datamation and informatization of the whole cathode protection system, and the system is more convenient to manage. When the cathode protection system of the target pipeline is managed according to the logic management subsection diagram, a cathode protection current is provided for each extracted cathode protection pipe section by the potentiostat or a sacrificial anode, so that the current densities of the extracted cathode protection pipe sections are the same, and conveniences in the management process are improved.
Description
technical field [0001] The invention relates to the technical field of cathodic protection, in particular to a method and device for extracting cathodic protection pipe sections. Background technique [0002] Existing steel pipelines for transporting oil, natural gas and other gases and liquids are usually buried underground, and the soil environment in which they are located may be relatively complex, so corresponding anti-corrosion measures need to be installed to prevent pipeline corrosion. Existing pipeline anticorrosion is mainly achieved by means of anticorrosion layer and cathodic protection. Among them, the principle of cathodic protection is to provide a protective current through a potentiostat or a sacrificial anode, so that the protected steel pipe acts as a cathode, inhibiting electron migration and preventing metal oxidation. In the specific work process, the effectiveness of cathodic protection needs to be tested. In the existing detection process, it is dif...
