High-temperature industrial pipeline is commonly found in large-scale petrochemical plant,the laying method is complex,and it is difficult to find corrosion defect only by relying on statutory regular inspection and daily macroscopic inspection.The online monitoring method of high-temperature industrial pipeline based on combined ultrasonic technology was introduced,the basic principle,advantage,limitation and system composition were analyzed,and three cases were given.It has been proved in practice that the online monitoring method based on combined ultrasonic technology is an effective technical means to meet the corrosion monitoring of high-temperature industrial pipeline in service.
