Inspecting and monitoring for biofouling and corrosion
- Structural Integrity Associates, Inc., San Jose, CA (United States)
Electric power generation plants typically use untreated surface water to transfer heat from various components to the ultimate heat sink for the plant. There are a variety of degradation mechanisms that can affect flow, heat transfer rates or structural integrity. Many times the systems are degraded by fouling and corrosion. This paper discusses the failure modes, particularly microbiologically influenced corrosion (MIC), as well as the tools and methods used for inspection and monitoring of these degradation mechanisms. In addition, the capability of an advanced inspection system, using laser profilometry and advanced analytical features in a single probe are presented. 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.
