The JD7 Bullet™ is a pressurised pipework leak detection system, with hydrophone and CCTV capability, for 100mm diameter pipework and above. The Bullet™ can be used on transmission lines. Access to pipework is possible through full bore fire hydrants, 38mm and above fittings, air valves, gate valves and hot taps at full mains pressure.
The JD7 Bullet™ offers 500m leakage surveys from a single insertion point and utilises the flow of water within the pipe to propel the sensor head along the pipework. All data is captured on-board the sensor head and automatically analysed in minutes following retrieval from the pipe.
The system is mounted onto pipework through a selection of fittings and/or ‘hot tappings’. This process makes access into the pipework simple. The acoustic device is fully capable for use on all pipe materials and diameters, allowing the system to be extremely effective for leak detection on all pipework. The on-board camera technology allows an overview of the pipework to be understood. This is particularly useful on the smaller diameter pipework, however less effective on the larger pipework due to light levels diminishing.
The maximum distance for each insertion is 500m due to the length of the cable supplied with the system. During insertion the maximum distance achievable will be influenced by the internal pipe conditions, flow of water being present and number of accumulative bends present.
The JD7 Bullet™ software is used to analyse all data with an automatic report generation feature included. The software displays both video and acoustic data in a number of detail levels and is extremely simple to operate.
Designed for use in two modes – free swimming or tethered. The head is propelled through the system by the water flow. Both video and acoustic data are recorded for analysis with the Bullet™ software.
