Problems solved by technology

[0003] Ultrasonic internal inspection of pipelines uses ultrasonic thickness measurement technology to judge the corrosion of pipelines, and uses the principle of ultrasonic pulse reflection. Therefore, during the inspection process, the sound beam must be perpendicular to the inner wall. If it is slightly deflected, it may not be possible to obtain an ultrasonic signal of sufficient strength.
However, it is difficult for the ultrasonic thickness measuring device to ensure that the sound beam is always perpendicular to the inner wall due to factors such as vibrati...

Abstract

The invention relates to a spherical densely-covered type probe ultrasonic thickness measurement device used for detection in a pressure pipeline. The invention aims at providing the device capable of satisfying a thickness measurement requirement of a large diameter pipeline, especially an elbow. And the device possesses characteristics of good stability during a motion process, high detection precision, high detection efficiency and the like. The spherical densely-covered type probe ultrasonic thickness measurement device used for detection in the pressure pipeline is characterized in that the device comprises a spherical shell, a spherical outer cover, several ultrasonic probes and a signal processing apparatus; the several ultrasonic probes are uniformly distributed on the spherical shell and are connected to the signal processing apparatus in the spherical shell through leads; the spherical outer cover covers an outer wall of the spherical shell and is provided with several through holes which correspond to positions of the ultrasonic probes.

Description

technical field [0001] The invention relates to the technical field of detection in pressure pipelines, in particular to an ultrasonic thickness measuring device for spherical densely distributed probes used for detection in pressure pipelines. Background technique [0002] As one of the five major modes of transportation, pipelines are the main means of transporting key energy media such as oil and natural gas. They play a vital role in the development and stability of the national economy and are the "lifeline" of the national economy. With the implementation of major projects such as "West-to-East Gas Transmission" and "Sichuan-to-East Gas Transmission" and the rapid development of urbanization, pipeline transportation has increasingly shown strong development due to its advantages of high efficiency, low cost, safety and reliability potential. Corrosion is the defect that is most likely to occur in the use of metal pipelines. During the use of pressure pipelines, with t...
