Underground Pipeline Cathodic Protection Online Monitoring System

At present, the underground water pipe leakage corrosion has become large petrochemical enterprise faces one of the important problems to be solved. The corrosion of the water pipe bad directly affect the petrochemical enterprise production water, water and fire water for living, etc; In addition, the corrosion of the water pipe leakage on the pipeline and the theme of the pipeline foundation structure stability of the influence. Therefore, the water pipe and pipe anticorrosion check the cathodic protection is to solve the pipeline safety and efficiency management important method, also is the important guarantee of the pipeline running smoothly.Delivery pipe line of cathodic protection effect reflected in potential test the effectiveness of the proposed method and data analysis of the scientific nature. When can direct test out lines or to polarization potential polarization potential, can more easily control pipe potential. But in some cases, there is a line of cathodic protection with only to reach a potential pipeline electrolyte low potential to protect pipelines, still there is a serious corrosion, the main cause is the cathodic protection of failure. At the same time, the pipeline cathodic protection potential is a dynamic parameters of every a pipeline of cathodic protection potential in different environment, different period, different positions are not all the same, rely on the way of paper records to can not meet every pipeline corrosion protection situation horizontally and vertically contrast analysis of the requirements, and thus can not grasp pipeline cathodic protection effect, the dynamic change, will eventually affect delivery pipe line underground cathodic protection effect and efficiency.This paper first underground water pipe of cathodic protection and related materials and structure of anti-corrosion and research status of cathodic protection at home and abroad were studied and discussed, analyzed and summed up the present a mature technology and method. Second, to solve the petrochemical enterprise in service of the water pipe anticorrosion, and combining the status of pipeline in service and related corrosion data, based on B/S structure as the foundation, the design and developing a set of underground water pipe cathodic protection on-line monitoring system, the realization of petrochemical enterprise internal operation of the underground line delivery cathodic protection online monitoring. Delivery pipe line underground cathodic protection online monitoring system to establish and maintain the delivery pipe line of all the basic information database, delivery pipe line pipeline corrosion parameters database and stray current library and information database, using data collection technology and mobile communication technology realize the automatic acquisition and pipe potential upload,. According to the actual pipeline in service and the related data of cathodic protection, of the pipes to the cathodic protection system to protect the potential for the analysis, risk that high pipeline section, there are some pointed maintenance in advance, prevent loss of accident of may, and improve the management of cathodic protection pipe quality, improve the working efficiency of the cathodic protection.
