Abstract

The invention discloses an ultrasonic pipeline flaw detection device, which has the function of completing flaw detection tasks for buried and underwater concealed pipelines, and can realize automatic turning especially for long-distance transmission pipelines, and can remove dirt on the inner wall of the pipeline to realize accurate flaw detection. At the same time, the device proposed by the invention can simultaneously realize efficient flaw detection in the liquid-filled pipeline and the empty pipeline, and solve the technical problem that the prior art cannot work uninterruptedly under variable working conditions.

Description

Technical field [0001] The invention relates to a flaw detection device, in particular to an ultrasonic flaw detection device for a concealed pipeline. Background technique [0002] Under the effects of long-term oxidation, gas / liquid pressure, impurity impact, etc., buried or underwater oil pipelines and gas pipelines will cause damage to the inner surface of the pipeline and cracks inside, which may cause safety hazards. At present, there are many pipeline flaw detection technologies, mainly including ultrasonic testing, eddy current testing, magnetic particle testing, radiographic testing, penetrant testing, visual testing, infrared testing, microwave testing and so on. In contrast, ultrasonic monitoring technology is relatively mature, with the advantages of high data resolution, low monitoring cost, and simple structure. Ultrasonic flaw detection is a method that uses ultrasonic energy to penetrate deep into the metal material, and when one section enters another section, r...
