Corrosion Properties of 20 # Pipelines Steel in Near-neutral Soils WANG Wen-he 1, a, YI Jun 1, b, SHEN Shi-ming2, c 1College of Safety Engineering, Chongqing University of Science & Technology, Chongqing, 401331, PR, China 1 Chongqing Academy of Safety Science and Technology, Chongqing, 401331, PR, China 2 Research Center of Engineering Risk Analysis Technology, SINOPEC, Nanjing, 210009, PR, China a wangwenhe518@163.com, byijun2366@yahoo.com.cn, csmshen@njut.edu.cn Keywords: Buried pipeline; near-neutral soil; corrosion mechanism; electrochemistry Abstract.
Y.J.Weng.et al [1-3] expressed that the electrochemistry behaviors of the metal material corrosion in soils have a different character in different stage by plentiful experiments; X.G.Li.et al [4-6] carried on research on soil corrosion tests chronically, they studied on corrosion mechanism and laws of X70 pipeline steel in KU'erle area in Sinking autonomous region and SU'geli area Inner Mongolia autonomous region deeply, which provides abundant datum to ensure safe operation for west-to-east natural gas transmission pipeline.
In the paper, the initial corrosion properties of the 20# steel in neutral soils along the jingling to Yangtze pipeline were studied, and the soil corrosive behavior and laws were discussed, which provided a reference for anti-corrosive design and cathode protection of buried pipeline materials. 1 Experimental procedure Specimens material is 20 # carbon steel, simulated solution is soils solution deployed according to the soils along jingling to Yangtze pipelines, the pH value is 6.5-8.0, and water content is large, and soil hole degree is small; analytical apparatus include SEM and XRD; electrochemical measurement system includes saturated copper sulfate electrode and graphite electrode, the polarization curves are measured by CHI electrochemical corrosion test system.
The main anodic corrosion mechanism reaction equations are as follows: Fe 2++ CO32→Fe CO3 Fe 2++ S2→FeS Except the soil electrochemical corrosion, corrosion of pipeline including partial corrosion in service, local corrosion and stray current corrosion should be researched and discussed necessarily. 3 Conclusions (1) As to 20# steel, in the near neutral soil, under the same buried time and temperature, 1 # and 2# specimen corrodes more seriously, and 3 # specimen corrodes less; the research results indicate that the corrosion property of soils along Yangtze River in Nanjing is higher; (2) EDS and XRD analysis indicate that: corrosion product of the 20 # steel pipe materials in three kinds of soils are mainly non-crystal; Fe (OH) 3 and Fe2O3, there are different degrees of sulfide, which has promoted the corrosion of 20 # steel; (3) From corrosion rates computed by weighted method and polarization curve, the results are accord with the surface corrosion
