| Summary: | Nuclear Radiation plays an important part in industrial application especially in radiography. Radiography is one of NDT techniques used for evaluation on material integrity or engineering structure. The tangential radiography method of large diameter pipes using the computed radiography system is a study or a method to determine the thickness of an industrial pipe. The process is being done using a radiographic system and the images produces were scanned, interpreted and analysed using the ISee program. From this program, we could actually manipulate or enhance the image to get a better picture of the image. We can also collect various dire information from this program. Apart from that, we can see if there is any cracks or reduction on the pipe's diameter due to corrosion or other externalities. This study is to compute or measure the diameter of the pipes without removing the insulation layer. This is important because in pipes used in industrial, it is very crucial to spot any weariness but at the same time using the most cost efficient, precise, and safest way possible. I used 2 pipes in this study. One with a diameter of 14 cm and width of 1cm while the other with a diameter of 6cm and a width of 0.2cm. The sizes of this pipes are chosen because these are the pipes similar to what is being used in the industry currently and we would like to simulate the actual procedures done on actual industrial pipes. Overall results shows that although some data are not exactly the same with the actual measurements, it is still can be used and any faults or errors may come from the one conducting the experiment, externalities or due to some errors in using the ISee program. However, this method has been proved to be very efficient and with further work done added with more experience,can be very precise. |
