Pressure-Decay Measurements Improve Bubble-Point Test
Abstract
Technique reduces by factor of about 100 minimum detectable flaw size in bubble-point test. By measuring rate of slow leakage, flaws as small as about 10-4 in. 2 (0.06mm2) are detected. Since technique does not require observation of screen, tests run on screens already installed inside tanks and pipes.
