PR-186-123716-R01 Analysis of Line Pipe Manufacturing Materials and Construction Practices

The objective of this work is to:

- Summarize, in spreadsheet format, historical API pipe specification requirements related to metallurgical attributes of the pipe,

- Collect pipe property data for a wide range of pipe sizes, grades, and vintages,

- Solicit subject matter expert input regarding the likelihood that pipe surface features and other attributes are sufficiently unique to allow pipe manufacturer and/or grade to be unambiguously determined, and to

- Describe nondestructive in-situ analysis methods that can be used on operating pipelines to determine metallurgical properties.
