Vacuum Decay Weld Leak Testing Methods, Test pressure: 0- -1 Bar

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-to-bottom plate welds 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 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 the vacuum box and cause injury to the operator 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
