Rapid Inspection of Tubing and Piping Due to Corrosion-Related Problems, Tri-Service Conference on Corrosion Proceedings.
Abstract
Military and commercial power-generating facilities often have failures to tubing and piping systems. In addition, marine tubing and piping systems are subject to increasing demands for better performance and longer service life. Primarily, the systems are degraded by fouling and corrosion. These can affect flow, heat transfer rates or structural integrity. This paper will discuss the failure modes, such as fouling and corrosion, particularly microbiologically influenced corrosion (MIC). MIC is the term for deterioration of metal by corrosion processes that occur either directly or indirectly as a result of the activity of organisms or their metabolites. Inspection methods for these degradation mechanisms are discussed. In addition, an advanced inspection system which integrates laser profilometry and fluorescence spectroscopy in a single probe is discussed. The probe scans the internal length of tube or pipe and generates a topographic map of the surface and characterizes the corrosion deposits to assess the severity of wall loss or pitting and the presence of deposits.
