Embodiment Construction

[0077] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0078] Such as figure 1 As shown, a pipeline non-destructive testing equipment provided by the present invention includes a mobile carrier 1 and a probe detection component 2. The probe detection component 2 is fixed or rotatably mounted on the mobile carrier 1, and the probe detection component 2 passes through the movement of the mobile carrier 1 in the pipeline. The inner wall of the pipeline is detected by moving, and the detection content of the probe detection component 2 can be determined according to the detection probe 24 with different detection functions that is carried according to actual needs.

[0079] Under normal circumstances, the axis line of the mobile carrier 1 is parallel to the axis line of the pipeline, and the mobile carrier 1 can automatically advance in the pipeline or advance with the flu...

Abstract

The invention discloses pipeline nondestructive testing equipment, and relates to the technical field of nondestructive testing, wherein the pipeline nondestructive testing equipment comprises a mobile carrier and a probe detection assembly; the mobile carrier moves in a pipeline along with fluid in the pipeline or moves through an advancing mechanism; the probe detection assembly comprises a detection part mounted on the mobile carrier, the detection part is provided with a detection end, and a detection probe is packaged in the detection end; and the pipeline nondestructive testing equipment further comprises a data processing unit, a first signal conditioning unit and a second signal conditioning unit, the detection probe comprises an excitation coil, a receiving coil and a passive resonance coil, and the passive resonance coil is located between the excitation coil and the receiving coil. Magnetization treatment equipment does not need to be additionally introduced during detection, so that the size of the system is greatly reduced, the requirement of the detection system on the internal cleanliness of the pipeline is reduced, the pipeline passing ability of the detection system is improved, and the cost overhead of the system is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a pipeline non-destructive testing equipment. Background technique [0002] Pipeline integrity is an important factor related to the safety of oil and gas transportation. Pipeline owners are very concerned about this. Failure of pipeline integrity due to pipeline corrosion or oil drilling and other damage methods will lead to major economic losses, environmental and social impacts; therefore, it is necessary to Regularly inspect the pipeline to find failures such as pipeline corrosion, deformation, leakage, etc., so as to ensure the safe and reliable operation of the pipeline. [0003] At present, methods such as magnetic flux leakage testing and ultrasonic testing are widely used in pipeline defect detection, and have become an important pre-control method to ensure safe transportation of pipelines, and are of great significance to eliminate pipeline risk factors...
