Probability of detection (POD) tests are a standard way to evaluate a nondestructive testing technique in a given set of circumstances, for example "What is the POD of lack of fusion flaws in pipe welds using manual ultrasonic testing?" The POD will usually increase with flaw size.
The first efforts to use ultrasonic testing to detect flaws in solid material occurred in the 1930s. [1] On May 27, 1940, U.S. researcher Dr. Floyd Firestone of the University of Michigan applies for a U.S. invention patent for the first practical ultrasonic testing method.
The removal method is controlled by the type of penetrant used. Water-washable, solvent-removable, lipophilic post-emulsifiable, or hydrophilic post-emulsifiable are the common choices. Emulsifiers represent the highest sensitivity level, and chemically interact with the oily penetrant to make it removable with a water spray. When using solvent ...
A defect detector would sound like this: (This was the read out of CSX train Q452-05 by the Campville Defect Detector on April 6, 2019. The defect detector is located at Campville, Florida, on the CSX Wildwood Subdivision.) CSX EQUIPMENT DEFECT DETECTOR. MILEPOST 7-0-0-POINT-1. NO DEFECTS. NO DEFECTS. TOTAL AXLES 7-3-8. TRAIN LENGTH 1-3-7-6-4 ...
The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...
One effect that can cause crack propagation is the presence of water and other liquids. When fluid fills a small crack and a train passes over, the water becomes trapped in the void and can expand the crack tip. Also, the trapped fluid could freeze and expand or initiate the corrosion process. Parts of a rail where defects can be found: head ...
