Applicability Analysis of Trenchless Corrosion Detecting Methods on Oil Pipeline
Today, oil pipeline leakage accidents have occurred frequently all over the world caused by corrosion damage and resulted in a lot of loss of life, economy and environment, so integrity management on pipelines can bring huge economical and social benefits. This issue summarizes the difficulties of traditional pipeline repair methods, i.e. need repair after excavation, big workload, the high cost of the project and even the impact on traffic, amenity and citizens' life and proposes the appraisal thought for the trenchless corrosion detecting based on the analysis of corrosive factors. There are some existing common methods of trenchless corrosion detecting, including leakage flux analysis, Ultrasonic analysis, potential gradient method, PCM detecting buried pipeline leakages, identifying anode corrosion tendency points, C-scan locating fracture spots at anticorrosion and thermal insulation layers analysis and metal corrosion loss method of detecting remained pipe wall thickness, etc. This issue analyses the adaptability of these methods for the pipeline maintenance and repair from the corrosive factors and circumstance and provides scientific advice and guidance for the security and reliable operation based on the advantages and disadvantages of these methods.
