JD7 Inline Pipe Inspections

The “JD7” pressurised pipe inspection and leak detection system allows all pipework, over 3” diameter, to be examined for condition and leaks whilst operating the network at full pressure. Introduced through existing hydrants and valves it creates no disruption for consumers. Similar to SAHARA Pipeline Inspection System:

The JD7 is designed for live inspection of large diameter water mains, the Pipeline Inspection System is one of the most accurate tools available for detecting leaks, pockets of trapped gas, and structural defects in complex networks of large diameter water mains.
 

This advanced technology leads to a range of benefits including:

  • Elimination of excavation costs
  • Pinpoint leaks in all pipe materials
  • Underground network management
  • Assess pipe structural integrity
  • Environmental impact through non- excavation
  • Identify leaks and resulting unaccounted for water
  • Monitor general pipe condition through leakage
  • Prove pipe integrity at critical network crossings (e.g. road and rail)

LDS1000™
The LDS1000™ system is the most advanced long distance CCTV and leak detection system available for use within pressurised trunk mains. The LDS1000™ is capable of 1000m surveys and includes state of the art High Definition CCTV technology coupled with ultra-high response hydrophone technology for precise leakage and acoustic surveys. All technology is compiled into one small sensor head, allowing all systems to be run together which drastically increases survey distances per day.

 

JD7Investigator™
The Investigator is a pressurised pipe inspection and leak detection system for 100m investigations within distribution water mains. The systems camera and hydrophone technology is matched for 3in. to 12in. diameter pipework for complete asset condition examination and leak finding. Unlike any other commercially available technology, the Investigator can be launched through fire hydrants, pressure fittings, air valves, gate valves and Quadrina’s at full mains pressure. The Investigator is capable of 100m travel with and against the water flow.

JD7Investigator+™
The JD7Investigator+ is a pressurised pipe inspection and leak detection system for 100m investigations within Trunk water mains. The systems camera and hydrophone technology is matched for 12in. diameter pipework and above for complete asset condition examination and leak finding. The Investigator+ can be launched through, pressure fittings, air valves, gate valves and Quadrina’s at full mains pressure. The Investigator+ is capable of 100m travel with and against the water flow.

HydrantCam™
JD7’s Hydrant Camera is the most unique product and won the UKSTT innovation award for the technology. The system is a true none-excavation technology and can be past up to 20m with or against the water flow by passing through fire hydrants. To date over 4,000 individual investigations have been carried out through fire hydrants. The technology includes the capability to navigate past loose jumper hydrants, buried hydrants and pillar style hydrants. Over 88% success rate is now achievable using this technology.

JD7Pipescan™
The PipeScan is an External NDT Manipulator designed specifically for pipework to allow precise condition assessment and evaluation. The system uses multiple ultrasonic probes to measure parent material, pit depths and general corrosion. The system is fully automatic and traverses electronically around the circumference of the pipework. For defect analysis there is a XY raster sequence that can be installed. Using this system, allows accurate remaining life expectancy of the pipework to be calculated where thousands of measurements can be acquired in minutes. The NDT system is designed and controlled by JD7 Group specifically for the water industry.


JD7Pipescan+™
The PipeScan+ is an internal NDT system, which is designed to be inserted through Air Valves or pressure points with an internal diameter of 2.0in. upwards. The systems are focussed to achieve wall thickness readings within all pipe sizes, including Cast Iron pipework. The system uses the water within the pipe as the couplant, allowing multiple readings to be performed. The system incorporates limit sensors, which ensure precise positioning for wall thickness measurements. Maximum operating pressure is 16 bar.

JD7ROV
The ROV has been designed for use within large bore pipe work targeted at water, gas and oil industries.
