Ultrasonic guided wave transducer that can be built into the inspection pipeline

Abstract

The present invention discloses an ultrasonic guided-wave energy transducer capable of being arranged in a detection pipeline. The ultrasonic guided-wave energy transducer includes a connector assembly, an electrical separation tee, a connecting pipe and an ultrasonic guided-wave energy transducer mechanism, the connector assembly, the electrical separation tee and the connecting pipe are sequentially connected, the ultrasonic guided-wave energy transducer mechanism is arranged at the end part of the connecting pipe and extends into the interior of a metal pipe, a ventilation end shaft and a seal end shaft are integrally connected by a core-connection shaft, the ventilation end shaft and the seal end shaft are respectively sleeved by two compressing sleeves, an electromagnetic coil structure is arranged on the core-connection shaft between the ventilation end shaft and the seal end shaft; a silicone tube sleeves outside the electromagnetic coil structure, both ends of the silicone tube are respectively pressed between one side compression sleeve and the ventilation end shaft and the other side compression sleeve and the seal end shaft; a magnetostriction strip material is welded on to a strip material supporting frame, two fixing rings of the strip material supporting frame respectively sleeve the two compressing sleeves. The ultrasonic guided-wave energy transducer can be arranged in a pipeline for detection, in the external, only simple gas charge and discharge is needed, the nondestructive testing whole process is simplified, the detection efficiency is improved, and the ultrasonic guided-wave energy transducer is suitable for batches of detection tasks.

Description

technical field [0001] The invention relates to the technical field of ultrasonic guided wave nondestructive testing, in particular to an ultrasonic guided wave transducer that can be built into a testing pipeline. Background technique [0002] With the development of social industry, the industrial and civil use of pipelines has increased dramatically. In order to ensure the safe use of pipelines, the task of pipeline inspection is becoming increasingly heavy. However, most of the ultrasonic guided wave transducers currently on the market for non-destructive testing of pipelines are coated on the outer surface of steel pipes or other profiles for testing. However, for some special occasions, such as it is inconvenient to place probes on the outer surface of brackets or special-shaped materials, and the small outer diameter cannot achieve better coupling effects, etc., it is impossible to use external construction probes for detection. In addition, the external installation...

Problems solved by technology

However, for some special occasions, for example, it is inconvenient to place probes on the outer surface of brackets or special-shaped materials, and the small outer diameter cannot achieve better coupling effects, etc., so it is impossible to use external construction probes for detection.

In addition, the external installation of most non-destructive testing probes is relatively complicated at present, and it often takes several processes to complete, and the efficiency of batch testing is low
