Corner Vacuum Box DELTA-VB300-2
Corner Vacuum Box DELTA-VB300-2
The Corner Vacuum Box DELTA-VB300-2 is a specialized tool designed for leak testing welded joints in sheet metal structures. Its corner-specific design makes it ideal for inspecting inside corners, such as where the bottom meets the sidewall at a 90-degree angle. Compact and precise, it’s perfect for testing tank bottoms, protective shells, vessel components, and other structures with one-sided seam access. As part of the DELTA-VB vacuum flaw detection system, it delivers accurate and reliable results for non-destructive testing (NDT).
The Corner Vacuum Box DELTA-VB300-2 is designed for use with an external vacuum pump. The vacuum pump is not included in the standard scope of delivery and can be ordered additionally.

Principle of Operation
The Vacuum Box DELTA-VB300-2 uses the bubble emission method to pinpoint leaks in three steps:
- Preparation: The welded joint is pre-coated with a foaming indicator solution.
- Testing: A vacuum chamber creates an air pressure drop over the test area.
- Detection: Visual identification of through-hole defects is achieved by observing gas bubbles forming in the foaming solution.
This method ensures fast and accurate leak detection, even in challenging corners.
