Vacuum Box Testing provides an effective method of identifying leaks and through-wall discontinuities in weld seams, particularly on storage tanks and fabricated structures. A vacuum is created over the prepared inspection area while a solution is applied to the surface; any leakage through a discontinuity produces a visible indication. The technique provides clients with a practical and economical method of verifying weld integrity and identifying leaks before an asset is placed into service or returned to operation.
