The corrosion resistance and risk assessment of pipelines are fundamental aspects of oil and gas transmission pipeline construction.Due to the unique characteristics of materials used in oil and gas transmission pipelines,such as exposure to outdoor environments and susceptibility to corrosion,they become key factors hindering pipeline quality and affecting the efficiency of oil and gas transportation.Strengthening the detection of corrosion resistance in oil and gas transmission pipelines is therefore a crucial measure to address these challenges.Based on this,this paper focuses on evaluating the corrosion resistance of oil and gas transmission pipelines and assessing the risks associated with corrosion,providing a scientific basis for selecting appropriate pipeline materials.The research findings indicate variations in corrosion resistance among different materials used in oil and gas transmission pipelines.By utilizing the fault tree analysis method to analyze corrosion risk factors in long-distance pipeline systems,the magnitude of risks can be determined.Targeted control measures for corrosion risk in oil and gas transmission pipelines are proposed,providing theoretical support for the safe operation and long-term stability of the pipelines.
