On-line Inspection Technology and Robot for Pipeline

Abstract

In the paper,the present situation of pipeline inspection technology is summarized,its current principle is presented,the main points of technology for in - pipe inspection robot are analyzed and the key research progresses are dis- cussed,which consist of flow field modeling and simulation,passing capacity,speed and gesture of movement control,miniaturi- zation,inspection precision and orientation precision of differential - pressure - driven in - pipe inspection robot,chaos dynamics methods for the evolvement behavior of pipe steel crack group in corrosion environment,and residual life prediction methods of pipeline.The study results put a firm basis for further research.
