A pipeline body safety management method

Abstract

The invention provides a pipeline body safety management method based on welding seam intelligent evaluation and big data comprehensive analysis. The pipeline digital management system is used to manage the completion data, third-party construction, high consequence areas and other information, and the weld film digital management system realizes the management of the weld electronic film; Step 2, according to the location information and the weld number, the weld film is Align with the weld information of the as-built data to realize the function of abnormal weld identification and subsequent processing; step 3, on the basis of reviewing the abnormal internal detection of the weld with negative film, review the internal detection signal of the weld without negative film, find If there are abnormal welds, and excavation verification is carried out, if the safe operation conditions are not met after excavation, repair them in time.

Description

technical field [0001] The invention relates to the technical field of pipeline management, in particular to a pipeline body safety management method based on weld intelligent evaluation and big data comprehensive analysis. Background technique [0002] In recent years, there have been many pipeline safety accidents, which have caused serious economic losses and social impacts. How to effectively manage the intrinsic safety of pipelines has become an urgent concern for all pipeline operating companies. [0003] Welds are an important feature of pipelines and one of the main causes of many accidents. It can be seen that their quality directly affects the intrinsic safety of pipelines. Nowadays, some progress has been made in the digitalization of weld film, and X-ray image processing, defect identification and analysis have been basically realized. The use during the construction phase of a project is extremely rare. [0004] At present, most weld non-destructive testing n...

Problems solved by technology

[0004] At present, most weld non-destructive testing negatives are stored at constant temperature and humidity, and manually evaluated. A few of them are stored in an independent system after being digitized by professional equipment, and cannot be intelligently evaluated or combined with other big data for comprehensive analysis and evaluation, especially for completed projects. The old pipeline with incomplete data is a big problem, or the quality management during the construction period, a lot of information, it is difficult to correspond with the welds one by one and find out which are redundant negatives and which welds have no negatives

[0005] The technical scheme described in the Chinese patent "CN108665452B Pipeline Weld Film Scanning Storage and Weld Defect Identification Method and System" realizes the scanning storage and defect identification of weld film, and this method realizes the digital management of existing weld film , but in terms of intelligent evaluation and comprehensive evaluation with other big data, it is impossible to do it. At the same time, it is impossible to manage the non-film welds that have not been put into storage

[0006] At the same time, in the era of big data, the intrinsic safety of pipelines involves all aspects, and it is not enough to judge only by electronic films of welds, especially for pipelines that have been put into operation and have incomplete data, such as: the quality of welds without films, and the lack of completion data during the construction period , Periodic internal and external inspection data during the operation period, stress concentration pipe sections, changing surrounding environment, high-consequence areas, etc., are all factors that need to be considered in intrinsic safety management. At present, there is no perfect method or process in China
