Research progress on corrosion and protection technology of oil and gas gathering and transmission pipeline
According to the corrosion problems of the gathering and gas pipeline,the pipeline material,ex-ternal corrosion and internal corrosion were analyzed;the chemical corrosion mechanism and electrochem-ical corrosion mechanism of pipeline corrosion were summarized,chemical corrosion was often accompa-nied by electrochemical corrosion,electrochemical corrosion was more common,and the harm was also more serious;multiple protective measures including pipeline material selection,coating protection,cath-ode protection and corrosion inhibitor protection measures were systematically introduced,and pointed that joint protection technology combined of corrosion technologies was the future development direction.
