This project was carried out as a study of effect of pipe diameter different and different pressure in piping system by using Acoustic Emission technique. The objective of this research is to investigate the flow rate in the piping system due to the pipe diameter difference and pressure different and evaluates type of signal produce from the acoustic emission technique for each type of pipe diameter in piping systems. A test rigs consist of a galvanized steel pipe that have two different diameters to run the experiments. The liquid that has been used is water and it controlled by the ball valve to setting the three different pressures. The source of the AE signal was from the ball valve that controlled the pressure but the effect of different diameter also play it roll because it can give a different flow rate that will show either the flow of water is low or high turbulent flow. The signal was captured using AE sensor with help of Acoustic Emission Detector 2.1.3 software. For all pipe diameter and pressure, the values of hits, counts and RMS (average, minimum and maximum) were recorded and analyzed. All the value recorded was compared to the different of pipe diameter and different pressure. The result shows that there almost no AE activities on the pipe that has big diameter compare to the smaller one. The conclusion has shown that the big pipe diameter will secure the safety because of the flow of the water that enter the pipe is low in flow rate and produced low turbulent flow compare to the small pipe diameter.
