Abstract
The utility model discloses a pipeline surface fault detection device. The pipeline surface fault detection device comprises a working table, wherein fixtures which are used for fixing a pipeline is arranged on the working table, a probe is further arranged on the working table, the probe is opposite to the pipeline which is fixed on the fixtures, and the probe is connected with an ultrasonic fault detector. The pipeline surface fault detection device has the advantages of being high in detection precision, safe and reliable, and good in stability.
Description
Technical field
The utility model relates to the detection technique application, particularly a kind of pipe surface failure detector.
Background technology
Along with the development of society, people have had more and more higher requirement to the quality of pipeline,
Therefore how pipeline being carried out production testing has just become an important topic.Due to the fine cracks and the scratch that exist many naked eyes can't see on pipe surface, the failure detector that therefore designs a pipe surface is just necessary.
Summary of the invention
The purpose of this utility model is in order to address the above problem, to have designed a kind of pipe surface failure detector.
Realize that the above-mentioned purpose the technical solution of the utility model is, a kind of pipe surface failure detector comprises worktable, worktable is provided with the jig for fixed-piping, also be provided with probe on worktable, and probe faces the pipeline that is fixed on jig, probe is connected with ultra-sonic defect detector.
The dynamic range of described ultra-sonic defect detector is not less than 30dB.
The lateral error of described ultra-sonic defect detector is not more than 2%.
The work centre frequency error of described probe is less than 10%.
The pipe surface failure detector that utilizes the technical solution of the utility model to make, detection speed is fast, and accuracy of detection is high, and is safe and reliable, good stability.
Description of drawings
Fig. 1 is the structural representation of pipe surface failure detector described in the utility model; In figure, 1, worktable; 2, pipeline; 3, jig; 4, probe; 5, ultra-sonic defect detector.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, it is the structural representation of pipe surface failure detector described in the utility model as Fig. 1, as shown in the figure, a kind of pipe surface failure detector, comprise worktable 1, worktable is provided with the jig 3 for fixed-piping 2, also is provided with probe 4 on worktable, and probe faces the pipeline that is fixed on jig, and probe is connected with ultra-sonic defect detector 5.Wherein, the dynamic range of described ultra-sonic defect detector is not less than 30dB; The lateral error of described ultra-sonic defect detector is not more than 2%; The work centre frequency error of described probe is less than 10%.
In the technical program, the dynamic range of ultra-sonic defect detector is not less than 30dB, and every grade is no more than 2dB, the ultra-sonic defect detector of preferred USD10, CTS-22 or three kinds of models of CTS-23.On the diaphragm surface of probe, scratches visible or mechanical damage cannot be arranged, the work centre frequency error of probe is less than 10%, T angle probe angular error and is not more than ± 2%, and angle probe incidence point deviation is less than ± 1MM.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; some changes that those skilled in the art may make some part have wherein all embodied principle of the present utility model, within belonging to protection domain of the present utility model.
