Abstract

The invention discloses a steel pipeline online ultrasonic detection device and method. The device mainly comprises a water collecting tank, a driving device, a support rolling platform, a coupling device, an ultrasonic probe, a control system, an ultrasonic detector and a data collection system. The driving device drives the ultrasonic detection device to automatically move and detection along the surface of the detected pipeline through the control of the control system, thereby avoiding the problem of pipeline quality defect caused by the missing detection of the traditional non-continuously point-by-point measurement check method. The device is high in measurement precision, the measurement result is more accurately, the manpower labor is saved at the same time; the device is suitablefor the high-speed requirement of the online detection and can be extensively applied to the occasion needing the online detection.

Description

technical field [0001] The invention relates to the field of ultrasonic detection, in particular to an on-line ultrasonic detection device and method for steel pipelines capable of continuous detection of seamless steel pipes. Background technique [0002] Ultrasonic testing technology is a commonly used non-destructive testing technology, which is currently widely used in the quality testing of pressure vessels, oil pipelines, mechanical parts, etc. In recent years, with the rapid development of pipeline transportation, steel pipelines have been applied to many fields. Before the steel pipe is put into production, acceptance work is required, and the wall thickness of the steel pipe is an important acceptance index. In the current actual production, the measurement of the pipe wall thickness mainly relies on the operator to measure the thickness of the end of the pipe with a micrometer or use an ultrasonic thickness gauge to measure the pipeline point by point. These trad...
