چکیده

Gas pipe failure caused by inner corrosion defects is one of the risk factors for the unscheduled shutdown of a plant. The pipes must be inspected to reduce the risk, but this requires a great amount of time and money, since gas pipes are quite long. This research proposes a screening method for the efficient inspection of gas pipes caused by aqueous corrosion. This screening method consists of three stages and includes thermographic and ultrasonic testing. We have developed new thermographic testing to find sludge in a pipe and to measure its wall-thinning distribution. The measuring principle and examples of the application of thermographic testing are introduced in this paper.

On-power Detection of Pipe Wall-thinned Defects Using Ir Thermography in Npps

The number of aging nuclear power plants (NPPs) has increased recently. Accordingly, the number of operational interruptions has increased due to malfunctions of the NPPs secondary systems. These cases occur in the secondary systems of NPPs with a range of structures due to fatigue, wall-thinned defects, corrosion, etc. Of these problems, wall thinned defects occur in the pipes by the diffusion...

Defect detection of pipes using shearography and lock-in infrared thermography

Dept.of Mechnical Design Eng., Chosun Univ., 375 Seosuk-dong, Dong-gu, Gwangju, Korea, [email protected] In this study, shearography and infrared thermography were used for measuring the wall thinning defects of the nuclear power plants pipes. It is very important to measure the wall thinning defects inside the pipes, because the wall thinning defects cause damage or destruction of the pipes. T...

Infrared thermography for high-temperature pressure pipe

High-temperature pressure pipelines are extensively used in petrochemical plant and power stations. Severe pits or wall loss defects can be internally produced after a certain period of time due to media corrosion and cavitation erosion. These defects finally lead to leakage of the pipes. In order to search for a good non-destructive method for these defects, a large pipe testing installation w...
