The stress corrosion behaviors of submerged arc welding X80 pipe, widely used in the West-East Gas Project II, are studied in five typical soil simulation solutions: (1) made from brown desert soil collected from Hami of Xinjiang Province, (2) meadow solonchak collected from Yumen of Gansu Province, (3) cinnamon soil collected from Yichuan of Henan Province, (4) yellow-brown soil collected from Wuhan of Hubei Province, and (5) red oil collected from Zhangshu of Jiangxi Province, respectively). The results showed a certain degree of stress corrosion susceptibility of X80 pipeline steel studied in those soil simulation solutions, but they were not serious. The stress corrosion susceptibility of the X80 pipeline steel gradually decreases from Yumen (meadow solonchak) soil, Yichuan (cinnamon) soil, Wuhan (yellow-brown) soil, Hami (brown desert) soil and Zhangshu (red) soil. Serious pitting occurred on the specimen in red soil simulation solution. The corrosion behavior of X80 pipeline steel in the other four kinds of simulation solutions was governed by general corrosion, although there were a few pitting occurrences on local positions.

Stray current interference may cause pipeline corrosion, which will result in premature failure of pipeline and potential safety problem to the persons who would touch the pipe during the work. The results of systematic field survey of the AC interference on an oil products pipeline showed that the range of quasi-stable AC interference was more than 20 km. Moreover, the risk of two separate pipeline sections among them was medium or worse. The relationship among corrosion rate, AC interference voltage, and AC interference current density was summarized after on-site tests. Finally, some mitigation suggestions were proposed.

The surface potential distribution of buried X80 steel under cathodic protection was calculated by finite element method. After comparing the results of simulation and experiment, the advantages and disadvantages of the numerical simulation method used in the present paper were discussed.
