Application of Sensors and Communication Gateway in Corrosion Monitoring System
Causes and hazards of corrosion
Oil and gas pipelines, pipelines for hazardous chemicals in refineries, storage tanks, etc. will be accompanied by corrosive substances such as sulfides, water-soluble acids, and water-soluble alkalis during use. In the process of production, processing and transportation, the production equipment and transportation pipelines are corroded. Mainly occur in low-temperature parts leak corrosion, high-temperature parts sulfur corrosion, and high-temperature parts naphthenic acid corrosion, which seriously affects the safety of the device, and even causes serious economic and social impacts; lack of long-term effective online inspection of on-site equipment and pipelines It is difficult to predict the risks of existing pipelines by using data analysis to predict the life of pipelines; the intervals between overhauls are too long, and it is difficult to measure the regular corrosion of overhead pipelines. Therefore, a device capable of online corrosion monitoring of pipelines is required.
Why should we monitor corrosion online?
Annual corrosion cost
● Design, processing and construction costs
● Material selection
● Increase the thickness
● Reduce corrosion
Operating costs
● Corrosion cost
● Corrosion maintenance related costs
● Reduce production running time
Limitations of manual corrosion measurement
● Problems caused by manual detection
● Human factors are too large
● Poor repeatability and reproducibility
● High cost in some harsh environments
Corrosion Monitoring System
The main function:
● Non-intrusive online corrosion monitoring, no pipeline damage
● Install sensors at designated locations to monitor changes in corrosion thickness in real time
● Corrosion measurement accuracy reaches 0.001mm
● It can calculate the corrosion rate, which is convenient for predicting the remaining life of the pipeline
● Corrosion cloud monitoring, check the corrosion status anytime and anywhere

Ex d IIB T4 explosion-proof design
Main advantages of online corrosion monitoring
Non-stop monitoring of low-risk pipelines, no need for periodic shutdown inspections, full use of pipeline in-service time, increase output value, and reduce inspection costs
Easy to operate, fast monitoring report, only one installation, no maintenance
No need for inspectors to periodically perform non-destructive inspections on corrosion
Automatic alarm to avoid losses caused by accidents caused by corrosion
Inspectors do not need to set up shelves, climb pipes and other dangerous behaviors for each inspection, which greatly improves the safety of monitoring/inspection personnel
Applicable to upstream, midstream and downstream companies in the oil and gas industry
● Oil and gas exploitation
● Oil and gas storage and transportation
● Refining and petrochemical
