The test pile is an essential part in the cathodic protection system, its main function is to detect the parameters of cathodic protection. Test pile also plays an important role in pipeline management and maintenance. The test pile must be installed along the pipe line according to its test function. The main components of the test pile are pile body, test wiring board, test wire and nameplate.


Pingsheng intelligent test pile automatically collects the data of pipeline protection potential, corrosion current, pipeline spontaneous potential, anode spontaneous potential and the voltage of the equipment's own battery regularly every day, and uploads the data to the cloud server regularly through the 4G/ NB-iot network.


The oil and natural gas long distance transportation pipeline mostly adopts anticorrosive coating and cathodic protection technology to prevent the anticorrosive coating from aging. Negative potential is applied to the pipeline by means of potentiostatic instrument or sacrificing anode, so that the pipeline forms cathode to the ground, forming protection and corrosion mitigation.


Intelligent test pile is an essential device in pipeline cathodic protection intelligent detection management system. It is mainly used for the detection of cathodic protection effect and operating parameters. Generally, one test pile is set along 1 ~ 2km of pipeline.


In the past, cathodic protection test piles were mostly tested manually by multimeter and tester (as shown in the figure above), which resulted in low efficiency, poor reliability and high risk, and was difficult to meet the requirements of cathodic protection monitoring of pipelines.


The intelligent test pile automatically collects the data of pipeline protection potential, corrosion current, pipeline spontaneous potential, anode spontaneous potential and battery voltage of the equipment at a regular time every day, and uploads the data to the cloud server regularly through the 4G/ NB-iot network.


The pipeline cathodic protection intelligent monitoring management system software is installed on the cloud server. The software is designed with B/S (browser/server) structure, and stores massive data with SQLSERVER database. It provides electronic map, data display, over-limit alarm, data query and various statistics and analysis functions. Support computer and mobile phone APP remote access.


The intelligent test pile is divided into two parts: the bolt body and the protective cover. The battery-powered intelligent monitor is installed in the protective cover to realize the functions of automatic data collection, automatic line switching, regular data uploading, and timely alarm of anomalies.
