Oil and natural gas are the important components of energy, and pipelines are the preferred way for their
transportation. However, with the increase of service time, oil and gas pipelines have serious corrosion failure problems.
Herein, the corrosion status of buried oil and gas pipelines in China was clarified, the common corrosion failure types of
the buried pipelines were summarized, the mechanism of acid corrosion, microbial corrosion, stress corrosion cracking
and hydrogen damage of oil and gas pipelines was discussed, and the effects of environmental factors such as temperature,
corrosive anions, cathodic protection potential, magnetic field, and alternating current on pipeline corrosion were analyzed.
In addition, discussion was performed for the present status of inadequate study on corrosion failure of buried oil and gas
pipelines and the mechanism and laws that are not cleared completely, so as to provide reference for the selection of research
direction of corrosion failure of buried oil and gas pipelines in the future.
