The vacuum leak detection box for tank bottom welds is specifically designed for conducting vacuum leak tests. This box is constructed from thin sheet metal and forms a rectangular, bottomless enclosure. The top of the box is securely sealed with a thick glass panel, ensuring a clear view during testing. The base of the box is equipped with an airtight sealing ring made of sponge rubber, which allows the box to be tightly fastened to the tank's bottom surface. The exterior of the box is coated with reflective white paint to enhance visibility and reduce glare. A short suction pipe and an intake valve are installed on the side of the box for easy connection to a vacuum pump. During the test, soapy water is first applied to the weld area. The vacuum box is then placed over the weld, and the internal pressure is reduced to approximately 55 kPa, ideally below -70 kPa. While maintaining the vacuum, the operator carefully observes the inside of the box for any signs of bubbles. If bubbles appear, it indicates a leak, and that specific area should be marked for further welding or repair. This method ensures accurate and efficient leak detection, making it a reliable tool in quality control processes.
