FIELD: oil-gas extractive industry, possible use for diagnostics of technical state of pipelines.
SUBSTANCE: corrosion speed indicator is mounted closely to pipeline, and its current indications are periodically read. Then indications of corrosion speed indicator are compared to appropriate threshold value. After that indication of corrosion speed indicator taken during a certain time period are summed and total values are compared to second threshold value. If received signals exceed at least one threshold value, emergency status of pipeline is predicted.
EFFECT: increased trustworthiness of predicting.
