Vacuum boxes are an ideal tool for bubble leak testing, an economical and proven weld inspection method. Vacuum boxes allow detecting weld non-conformance and locate leaks for both new welds during fabrication, or in-service inspections during preventative maintenance. Very large leaks and small leaks can be detected simply and rapidly when using a good quality, commercial vacuum box.

Vacuum boxes are used in many industries and/or applications such as:

  • Petrochemical storage tanks (tank bottoms)
  • Railroad tank cars
  • Shipyards
  • Lap welds, butt welds, and shell to annular welds
  • Piping systems and pressure vessels
  • ERW pipes and pipelines

Not all Vacuum Boxes are born equal

Ergonomic design 
Unlike some home-made solutions, our vacuum boxes have been designed with the operator in mind. Integrated handles make it easy to position the box properly on almost any weld, in almost any environment. 

Superb illumination, all the time
Thanks to powerful, integrated LEDs, our vacuum boxes make it easy for operators to locate leaks. The internal LEDs eliminate the view window reflection that occurs when external lights are used to brighten the weld inspection area. You can easily turn the LEDs on and off, eliminating the need for you to move standard halogen floodlights. The optional built-in LEDs provide the recommended light intensity along the weld under test by API 650.

Better accuracy
Our vacuum boxes come with an industrial 50.8 mm (2 in) face pressure gauge rated to 762 mm (30 in) of mercury as required by ASME V Article 10–Bubble Test Vacuum Box Technique. The calibrated gauge offers the necessary confidence in your inspections by ensuring the proper recommended vacuum is generated.

Safer and quicker
Using a built-in calibrated vacuum relief valve ensures reaching the recommended vacuum under international standards. The advantage of such a valve is that once the necessary vacuum is achieved, the relief valve opens and maintains this vacuum, preventing it from damaging the vacuum box and keeping the operator safe.

More flexible 
Two different approaches exist to generate vacuum: using an electric pump (an Air Vacuum Generator – AVG), or using and external compressor.  Our vacuum pumps are available in different configurations, so you can use the approach you prefer, or both when opting for the “Dual” configuration. 

 

Did you know?

In order to perform a valid inspection using a vacuum box, it is important to remove any signs of rust, grease, oxide films, or other visible surface contaminants.
