The electromagnetic guide wave detection solution for fluid transmission pipelines in the petroleum and petrochemical industry uses electromagnetic guide wave technology to meet the rapid and accurate requirements of customers for long-distance pipeline corrosion detection.
Electromagnetic ultrasonic guide waves use electromagnetic fields as a medium to send and receive ultrasonic waves, so no ultrasonic coupling agent such as oil and water are required;
Since no coupling agent is needed, there is no coupling change problem, and the detection sensitivity is stable;
The guide wave has a long propagation distance, a small attenuation coefficient, and a high detection efficiency. For the rebar test in the air, the edge echo at 100 meters can be found.
