System and method for detecting and evaluating corrosion of buried pipeline

Abstract

The invention discloses a system and a method for detecting and evaluating corrosion of a buried pipeline, and belongs to the technical field of corrosion resistance of pipelines. The system comprises on-line soil corrosion detection equipment, on-line pipeline corrosion detection equipment and a corrosion evaluation and detection system, wherein the on-line soil corrosion detection equipment is arranged in the soil around a pipeline; the on-line pipeline corrosion detection equipment is arranged on a test pile of the pipeline; and the on-line soil corrosion detection equipment and the on-line pipeline corrosion detection equipment are respectively connected with the corrosion evaluation and detection system in a wireless data communication manner. By adopting the online-detection equipment, soil and pipeline corrosion data can be acquired timely, and the corrosion evaluation and detection system comprehensively and completely analyzes the monitored data of the soil and the pipeline; and the system can completely and systematically analyze the data relevant to the corrosion of the buried pipeline and timely evaluate the corrosion situation and the residual service life of the pipeline so as to timely judge the corrosion state of the pipeline.

Description

technical field [0001] The invention relates to the technical field of pipeline anticorrosion, in particular to a buried pipeline corrosion detection and evaluation system and method. Background technique [0002] With the rapid development of the national economy, the construction of buried pipelines has entered a stage of rapid development. The total mileage of buried pipelines that has been completed and put into operation has exceeded 100,000 kilometers. Corrosion and perforation incidents of pipelines occur from time to time, resulting in the loss of oil, gas and water, environmental pollution and personnel Huge damage, huge loss. Using reasonable technical means to evaluate pipeline corrosion and predict the remaining life of pipeline can effectively help pipeline management departments to manage pipelines, improve the efficiency, accuracy and scientificity of management, and reduce the harm caused by pipeline corrosion. Therefore, the corrosion assessment and life pr...
