Pipeline quality gas is normally dried in Triethylene Glycol (TEG). This paper explores how TEG vapor can exist in a pipeline in a similar manner to water, and possibly lead to corrosion. TEG vapor can condense at long distances down a gas pipeline as the line cools.

This paper presents a recent effort to further minimize the threat of corrosion by wet ammonium chloride salt. Includes advances in fundamental understanding salt behavior, predictive mdeling, integration of models with process and operations.
The purpose of this paper will be to: (a) review published literature to characterize and classify speciation related to the types of impurities encountered in opportunity crudes; and (b) describe and categorize published case studies of corrosion in crude unit overhead operations.
This paper illustrates how appropriate use of predictive flow models and pipeline inclination profiles, in conjunction with dew point analysis, improves the prediction of locations susceptible to internal corrosion.
This standard, SSPC-SP 7 (WAB)/NACE WAB-4, defines the "Brush-Off" level of surface cleanliness for wet abrasive methods. One of five wet abrasive (WAB) levels: (White Metal, Near-White Metal, Commercial, Industrial, Brush-Off)
