Is visual inspection effective? Overall, the visual inspection method on its own cannot produce the same quality results as other nondestructive testing (NDT) methods. For one, it cannot detect certain minute flaws regardless of how keen an eye or how much experience an analyst has. Even the use of visual aids and tools is sometimes insufficient—and even minor defects may develop into ...

Sewer systems are costly to construct and even more costly to replace, requiring proper asset management. Sewer asset management relies to a large extent on available information. In sewer systems where pipe corrosion is the dominant failure mechanism, visual inspection by closed circuit television (CCTV) and core sampling are among the methods mostly applied to assess sewer pipe condition. This ...

Electromagnetic detection is a very important non-destructive testing method and is widely used. Magnetic flux leakage is a magnetic method of nondestructive testing that is used to detect corrosion and pitting in steel structures, most commonly pipelines and storage tanks. The basic principle is that a powerful magnet is used to magnetize the steel. When used in combination with other methods, ...

ABSTRACTA condition assessment study for the Water Works and Sanitary Sewer Board of the City of Montgomery’s (MWWSSB’s) West Catoma Interceptor (WCI) was conducted in 1998 and 2003. The WCI was evaluated in 1998 using core sampling, closed-circuit television, and manhole (MH) inspections. Approximately 193 MHs and 65,000 linear feet (LF) of pipe were inspected. A subsequent study conducted in ...
