Abstract: Responding to needs expressed by corrosion personnel, a consortium of natural gas transmission and distribution companies have developed a new tool called the Stray Current Mapper (SCM). This development started in 1997 and the product is now ready for marketplace introduction. During the development process, the members of the New York Gas Group (NYGAS) as well as several other gas companies and consortia were involved in several design iterations, field tests, and feedback sessions. This paper describes the tool, how it operates, and differences between dynamic and stray currents and the impact that they have on pipelines. It will also provide case studies where the SCM was used to identify the problem, aid in the selected solution, and then verify that the problem was solved.
