Abstract: On the basis of the current research situation on management technology of natural gas pipeline integrity, the framework process of management of natural gas pipeline integrity is summed up and main content of the management of natural gas pipeline integrity is systematically expounded.main factors that affect the safety of the pipeline and accident consequences of natural gas pipeline are analyzed, and pipeline integrity test is presented. Measures for controlling natural gas pipeline's corrosion are advanced and proposal for developing management of gas pipeline integrity is put forward at the same time.
