JD7 Limited products

The system is used for 3” diameter pipework and above for complete asset condition examination and leak finding. Access through fire hydrants, 1.5in. and above pressure fittings, air valves, gate valves and Quadrina’s at full mains pressure.

Piloted in Northern Gas Networks (UK), in 2013 JD7 commercially launched its live gas insertion system capable of 100m travel.  This technology incorporates not only high resolution CCTV camera sensors but also a highly sensitive acoustic sensor coupled with a sonde. The acoustic sensor is used for precise leak detection pinpointing in all materials and pressures.

The JD7 Investigator LightTM is a fully integral pressurized pipe inspection and leak detection system designed for harsh environments. Designed for 3in. diameter pipework and above for complete asset condition examination and leak finding. Access through fire hydrants, 1.5in. and above pressure fittings, air valves, gate valves and Quadrina’s at full mains pressure.

The JD7 Voyager is the most advanced ROV Crawler system on the market and is compatible with water, gas and industrial pipelines. The system is a long range 5000m capable crawler with full high resolution laser profiling technology incorporated. The system offers both tethered and untethered configurations. In tethered mode 1km is achievable, allowing full control.

The Jd7 PipeScan+ is an internal ultrasonic manipulator incorporating focussed ultrasonic probes coupled with a hi resolution camera system and 512Hz sonde. The PipeScan+ allows pipework of all materials to be scanned whilst remaining in service, allowing a full dimensional survey to be achieved including multiple wall thickness measurement, corrosion and flaw identification along with lining thickness.
