Flat bottom vacuum box bubble leak testing 30.00" L x 8.00" W x 1 1/2"H 800 mm x 200 mm x 35 mm More Efficient: Vacuum Box LED The optional built-in LEDs provide the recommended light intensity along the weld under test by API 650. 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 as you move around the tank Better Accuracy: Calibrated Gauge The V750 Vacuum Box comes 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: Vacuum Relief Valve Using a calibrated vacuum relief valve ensures 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 or injure the operator. Electric Pump or Compressor Driven The BHFTECH Boxes generates a vacuum using an electric pump or an Air Vacuum Generator (AVG), and an external compressor. Inspection companies tend to use the electric pump because it is more flexible, while construction companies tend to use AVG systems. High-pressure and Low-pressure Models Vacuum boxes are rated to 20 in of Hg (10 psi/0.7 bar) recommended for in-services tanks or 10 in Hg (5 psi/0.4 bar) recommended for new tanks. BHFTECH models are rated to 20 in of Hg.
