Диагностирование состояния металла трубопроводов на основании тепловизионного мониторинга

Abstract

The work is devoted to the application of the thermal method of nondestructive testing to diagnose the development of internal defects in pipelines during transportation of technological flows of liquids and gases. When transporting process flows on the walls of pipelines, corrosion of the material occurs. Through thermophysical modeling, the process of defect development was investigated. (thinning the wall). Test samples with embedded defects of different depths were developed. A stand and experimental technique were developed. Studies have revealed the dynamics of the temperature field in places of defects and defect-free zones of the sample. The results obtained make it possible to forecast the time to reach the critical level of the temperature anomaly at the defect site.
