The V750 vacuum box has been designed for operators and according to API 650/653 recommendations. Bubble (or vacuum box) leak 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 bottom plate welds. of the tank and the welds of the wall and bottom joint plate.
Features
- Designed according to API 650/653 recommendations.
- Weld inspection length 750 mm (29.53 in.), 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 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 in large lap welds.
- Electric or compressor driven vacuum pump.
High and Low Pressure Models
Vacuum boxes are rated for 20 in. of Hg (10 psi / 0.7 bar) recommended for tanks in service or 10 in. of Hg (5 psi / 0.4 bar) recommended for new tanks. The V750 models are rated at 20 inches Hg, but if you are interested in a low pressure model the V600LP and V400LP models are available.
