Problems solved by technology

[0003] At present, most of the pull tests of existing in-line detectors use dry linear pull test devices, which do not simulate the effects of pull tests in liquid environments.
On the other hand, the pull test pipeline has a small number of defects and cannot effectively cover more types of defects, which affects the effective test coverage of the defect quantification algorithm
[0004] The embodiment of the present invention provides a linear pull test device and a pull test method for a detector in a pipeline, which solves the influence of the pull test in an unsimulated liquid environment in the prior art, and the number of defects in the pull test pipeline is small , can not effectively use the artificial intelligence method to determine the quantitative relationship between the defect signal and the defect position, category, length, width, and depth information

Abstract

The invention provides a pipeline inner detector linear traction test device and a traction test method. The pipeline inner detector linear traction test device comprises a test liquid tank, a main winch, an auxiliary winch, a sending support, a receiving support, a traction test tube and a pipeline inner detector, wherein the required pipeline damage can be simulated in the traction test tube, the pipeline inner detector starts from the sending support under the action of the main winch and / or the auxiliary winch and moves to the receiving support through the traction test tube, and a plurality of types of defects are pre-arranged in the traction test tube and are used for being detected by the pipeline inner detector to obtain test data.

Description

technical field [0001] The invention relates to the technical field of in-pipeline detector testing, in particular to a linear pull test device and a pull test method for an in-pipeline detector. Background technique [0002] Pipelines are an important way of long-distance transportation of oil and natural gas. Pipelines work under high pressure, long distances, and harsh external environments. Due to various reasons such as transmission medium corrosion, stress, construction damage, and natural disasters, various defects will occur on the pipe wall. , These defects are very harmful to the safe operation of the pipeline, and early detection of defects is an important means to guide pipeline maintenance work and maintain pipeline integrity. At present, the most common in-service detection method for pipeline defects is the in-pipeline detection technology. After the development of the in-line detector is completed, its performance needs to be comprehensively tested and teste...
