In view of problems existed in the application of pipeline integrity management and through deep analysis of typical accidents at home and abroad ，this book elaborated on technical standards of pipeline integrity，failure mechanism，and integrity assessment technologies of in line inspection，pressure test assessment and DA technologies (ECDA，ICDA,SCCDA)，which solve the problems of matching between inspection & detection signal and size accuracy. Corrosion assessment technology was focused on pipeline black powder and inhibitor prevention，inteal coating assessment，and fitness-for-purpose （FFP）assessment technology was given. for weld seam of pipeline，image processing and recognition technology for weld film includes image processing，defect feature extraction，defect classification and identification was proposed，and ultimately the welds defects was identified and found automatically.

This book also aims at the edge technology of pipeline integrity，and pipeline station facilities integrity was studied and full-size pipeline explosion assessment were done，guided wave tomography for quantification of corrosion damage in Fluid-Filled Pipes was produced. Some cases was quoted from pipeline operation and maintenance practice completely，which contribute to apply into the practice，so as to minimum the risk. This book mainly read for oil and gas pipeline operation and maintenance management personnel，and may for being engaged in the technical personnel and administrative personnel of the oil and gas storage and transportation and plumbing engineering refers.
