During the past ten years a considerable amount of interest has been manifested in the study and mitigation of microbiological anaerobic corrosion. Mr. Raymond F. Hadley (1)(2)(3) and Professor T. D. Beckwith (4) have conducted extensive research work in connection with the study of this type of corrosion and have published invaluable information relating to the theory and mechanism involved in the process of anaerobic corrosion.
The discussion presented in this paper relates to a five-mile section of 63.413-pound, 24-inch, welded gas transmission line having a wall thickness of 0.250 inch and laid in the year 1930. The line was coated with a commercial, tar enamel, but was not wrapped.
Figure 1 shows a right-of-way plat of the line. The corrosive areas of primary concern are the single line crossing on the North Canadian River, and the mile long section of pipeline...
