摘要：

The results of an in-tube inspection of two gas pipelines of a single 110-km section of a multiline pipeline route are analyzed. The manifestations of the corrosive and stress-corrosive forms of damaging in the pipeline section are quantitatively compared. It is shown that for the existing differences between the gas pipelines with respect to the number of corrosive flaws and the nature of their distribution, the data for one of the gas pipelines of the route are insufficiently representative for the other pipelines in order to judge unambiguously the location and the degree of the damage development by the stress-corrosive cracking mechanism or in the result of corrosion.
