Bubble leak testing of tank bottom plate welds and shell to bottom plate welds The BHFTECH vacuum box has been designed for the operators according to API 650/653 recommendations. Bubble leak or vacuum box testing is an integral part of tank inspections as required by the American Petroleum Institute (API) and other international standards associations to establish the condition of tank bottom plate welds and shell-tobottom plate welds Flat Bottom Vacuum Box Features Designed to API 650/653 recommendations 750 mm (29.53 in) weld inspection length, improves inspection times and reduces operator fatigue Integrated LED lights provide the required light Flat Bottom Full Transparent intensity as specified by API and ASME inspection standards Screen glare and shadows from external light sources are eliminated Calibrated vacuum relief valve ensures the correct vacuum is generated, too high a vacuum can damage Inside Corner Vacuum Box the vacuum box and cause injury to the operator Bubble Leak Testing Superior build quality with robust cast aluminum body Two-stage seal design to improve initial vacuum, especially on large lap welds Electric vacuum pump or compressor driven Model No Flat Bottom box for testing butt welds on flat surfaces Inside Corner Vacuum Box Bubble Leak Testing Corner vacuum boxes are specifically designed for testing the inside corner, where the bottom meets the sidewall at 90 degrees Complete Transparent Flat Bottom box for testing butt welds on flat surfaces 110 General Patters Road.

More Efficient: Vacuum Box LEDs 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...
