FLAT BOTTOM VACUUM BOX BUBBLE LEAK TESTING

FLAT BOTTOM VACUUM BOX BUBBLE LEAK TESTING Vacuum box testing is a non-destructive examination (NDE/NDT) used for locating welding leaks. A vacuum box and a compressor create a high or low-pressure vacuum and a detergent solution is applied to the test area. The detergent bubbles help to identify the leaks within the created pressure envelope. The main objective of the Vacuum box testing technique is to locate leaks in welds due to through-thickness discontinuities. This is accomplished by applying a solution to a weld and creating a differential pressure across the weld causing the formation of bubbles as leakage gas passes through the solution. This testing is to be performed prior to any main vessel or tank testing following the completion of all welding. This article will briefly explain the leak testing procedure using the vacuum box method that can be used for all metals. 1-Flat Bottom box for testing butt welds on flat surfaces 2-Operates using compressed air • Dimensions: 600mm X 200mm X 150mm Note: Customized VACUUM BOX also available.

Inside Corner Vacuum Box Bubble Leak Testing

Inside Corner Vacuum Box Bubble Leak Testing Vacuum box testing is a non-destructive examination (NDE/NDT) used for locating welding leaks. A vacuum box and a compressor create a high or low-pressure vacuum and a detergent solution is applied to the test area. The detergent bubbles help to identify the leaks within the created pressure envelope. Corner vacuum boxes are specifically designed for testing the inside corner, where the bottom meets the sidewall at 90 degrees. Operates using compressed air. Dimensions: 500mm X 150mm X 150mm Note: Customized VACUUM BOX also available.
