The steel pipe (continuous oil pipe) online intelligent monitoring equipment is a new type of non-destructive testing technology that integrates industrial Internet + magnetic memory AI weak magnetic sensing technology + machine vision recognition monitoring technology for full lifecycle safety monitoring of steel pipes (continuous oil pipes). Through the integrated application of this technology in oilfield safety production, it enhances the perception, monitoring, early warning, disposal, and evaluation capabilities throughout the full lifecycle of steel pipes (continuous oil pipes), realizing the transformation from static analysis to dynamic perception, from post-event emergency response to pre-event prevention, and from manual detection to intelligent monitoring, thereby improving the intrinsic safety level of steel pipes (continuous oil pipes). The equipment is fixedly installed at an appropriate position on the operating path of the steel pipe (continuous oil pipe). It continuously and uninterruptedly collects magnetic energy potential difference information distributed and memorized in the volume elements of the steel pipe (continuous oil pipe) through weak magnetic sensing, and defect information collected by machine vision intelligent recognition technology. This enables real-time qualitative, quantitative, and positional detection, as well as big data quantitative analysis of various damages caused by strength loss, such as fatigue cracks, wear, deformation, corrosion pits, mechanical damage, etc.; as well as manufacturing quality defects including weld defects, through holes or blind holes in the pipe, groove defects, surface scratches, ovality, impact pits, and other defects of various grades. Thus, it achieves accurate assessment of the current safety status and full lifecycle of the steel pipe (continuous oil pipe).
