The leak analysis test on the SS 316L sanitary pipe which was soaked in a pH 4 solution aims to determine the exact cause of the leak in the pipe. Pipes that are filled with acid with a pH of 4 will sometimes leak and according to the technician, the leak is caused by the acid in the pH 4 solution in the pipe. Therefore, this test is to confirm that the damage is caused by an acid with a pH of 4. It turns out that it is true that an acid with a pH of 4 can cause erosion of the pipe, which over time can cause the pipe to leak. This test uses a gravimetric test method which aims to find out how much weight the object erodes in 24 hours / 1440 minutes.
