Oil And Gas Pipelines Cathodic Protection On-line Monitoring System For Research

Today's oil and gas transmission pipeline is the main channel of domestic oil and gas transmission,so the oil and gas pipeline corrosion protection is still a classic issues concerned by the people,and the cathodic protection system is in recent years the domestic primary scheme to solve the problem of oil and gas pipeline corrosion,with the development of the cathodic protection technology and the demand of pipeline construction is increasing,cathodic protection in domestic mainly collected in accordance with the schedule of artificial records,high workload,data entry is not stable,not real-time data analysis,is still the people need to solve all these problems.problems.In this paper,the oil and gas pipelines cathodic protection of online monitoring system for research,first of all,according to the selected topic background and significance of the cathodic protection are analyzed in classification at home and abroad,summarizes the method of cathodic protection are sacrificing anode protection,impressed current protection and drainage protection,then according to the types of protection of cathodic protection and good relations in various type of protection in practical use,in the rule of maximum protection potential,100 mv polarization and GPRS communication technology under the condition of on-line monitoring system for cathodic protection of the hardware and software of singlechip processor system and PC data to study the interactive display,and ultimately through the scene of the actual presentation to complete this thesis.
