Pipeline corrosion detection refers to in-pipeline detection with the purpose of detecting metal loss such as pipe wall corrosion. It is a basic method to understand the damage of pipelines in service in the working environment and ensure that defects and damage are detected before serious problems occur in the pipeline.
In the past, the traditional methods for detecting pipeline damage were excavation inspection or pipeline pressure testing. This method is very expensive and generally requires stopping the pipeline. Currently, corrosion detectors using magnetic flux leakage technology and ultrasonic technology are used for in-pipeline inspection, which can detect the size and location of corrosion pits, stress corrosion cracks, fatigue cracks and other damage.
