  • Is Visual Inspection an Effective NDT Method?

    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 ...

  • Comparison of core sampling and visual inspection for assessment of concrete sewer pipe condition

    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 ...

  • Heron Articulating Rigid Videoscope is perfect for inspecting Scuba Cylinders

    Scuba cylinders need to be visually inspected a minimum of once a year, and often times more frequently depending on the use of the cylinder. These inspections are done to ensure the ongoing safe use of these cylinders. Scuba divers rely on them completely when diving, and therefore they need to be maintained excellently. Scuba cylinders come in various sizes and hold air at pressures up to 300 ...

  • Magnetic Flux Leakage Testing Equipment

    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, ...

  • DAM GOOD ROVS - The inspection and maintenance of vital resource facilities is an integral part of any regions health and stability management program

    Providing consistent output while driving down inspection and maintenance costs is a key activity for those involved in the provision of such services, and requires the monitoring and assessment of relevant new technologies and techniques.

  • Process to Estimate Sanitary Sewer Pipe Remaining Life Provides MWWSSB Remedial Decision Information

    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 ...
