Air cooler is a kind of equipment commonly used in long-distance natural gas pipeline stations.The corrosion condition of its tube bundle is the key factor affecting normal operation.This paper mainly analyzes the damage mode of the air cooler tube bundle in long-distance natural gas pipeline stations,adopts the on-site detection methods of ultrasonic thickness measurement,remote field eddy current testing and endoscope inspection,and evaluates the detection results to form a complete research method on the corrosion status of the air cooler tube bundle.
