How Does Vacuum Box Testing Work?

A vacuum box is placed over the weld or component to be tested, and a vacuum is applied inside the box. Soap solution or a similar medium is applied to the area. If leaks are present, bubbles form in the solution, providing a clear visual indication of defects.

Benefits of Vacuum Box Testing

Cost-Effective

Vacuum Box Testing is a straightforward and efficient inspection method that requires minimal equipment and preparation. It’s a highly economical way to detect through-thickness leaks in components and welded joints, especially during construction or routine maintenance.

Highly Visual

One of the key advantages of this technique is the immediate and visual confirmation it provides. The formation of bubbles under vacuum pressure offers a clear and easily interpretable indication of any leaks or defects, making it easier to assess and document the results.

Non-Destructive

As a non-invasive testing method, Vacuum Box Testing does not alter, damage, or degrade the material being inspected. This makes it ideal for ongoing maintenance programmes where component preservation is critical.

Versatile

Vacuum Box Testing can be applied to a wide range of flat and curved surfaces, and is suitable for both in-field and workshop environments. It’s commonly used across various industries including oil and gas, marine, power generation, and infrastructure, for everything from small tank welds to extensive pipeline systems.
