Pipelines that cross complex geological terrains are inevitably threatened by natural hazards, among which landslide attracts extensive attention when pipelines mountainous areas. The landslides typically associated with ground movements would induce additional stress on the pipeline. Such state of under interference seriously damage structural integrity Up to date, limited research has been done combined hazard and pipeline analysis. In this paper, a multi-parameter integrated monitoring...
The development of oil and gas pipelines in the direction large diameter, high pressure, steel grade has put forward higher requirements for pipeline inspection technology. Traditional magnetic flux leakage (MFL) internal techniques suffer from low micro-metallic defect rates are significantly affected by velocity effect. Similarly, eddy current (EC) technologies exhibit limitations capability wall defects noticeably influenced lift-off effects. This paper addresses these challenges...
Caliper pipeline inspection gauges (PIGs) are essential devices for ensuring the safe operation of oil and gas pipelines. However, traditional caliper PIGs cannot detect multiple pipe deformations at one time, equipment components complex be reused. With continuous improvement detection performance requirements in practical application fields, there is an urgent need a detector that can accurately quantify deformation along with simple structure. To this end, new type flexible PIG strain...
For natural gas pipelines across the area in southwest China(2470km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ), small baseline subset SAR interferometry (SBAS-InSAR) and differential InSAR (D-InSAR) are used to acquire deformation information of entire from 2016-07 2021-21 based on image data Sentinel-1A ALOS-2 high-resolution synthetic aperture radar (SAR). The results show that technology, as an emerging technical means...
