LEISTER vacuum leak detection cover/negative pressure leak detector

Application: Tank weld vacuum box detector/vacuum leak detection cover is used in tank weld leakage testing with reliable performance. If there is leakage in the weld after vacuuming, the foaming material coated on the surface of the weld will generate bubbles and the weld defects will be detected. Features: The tank weld vacuum box detector/vacuum leak detection cover is lightweight and easy to carry for non-destructive testing. It can detect lap/butt welds on the bottom plate of any size tank.
Operation: Carry out air pressure test on the double weld, seal both ends of the weld, insert a pressure leakage measuring needle at one end, and then inflate the cavity with air pressure. If there is no change in pressure for a few minutes after inflation, the quality of the weld is qualified. If there are any changes, apply detection fluid. For local joints such as hole repairs, joints, etc., use the vacuum detection method.
