When you need to assess a pipeline, do you think it will work better to inspect it at no pressure or while it's under pressure? If you selected "under pressure", you're right, because a pressurized inspection mimics the system's normal operating conditions. But how do you inspect the system while it's under pressure? Using the camera Team EJP deploys in this type of situation, the JD7 Investigator. The Investigator provides some serious data in terms of video, acoustics and sonde measurements, helping track down your pipeline problems fast. Here's what you need to know:

What it is

PipescanThe JD7 Investigator is a non-disruptive pressurized water main camera that provides acoustic, CCTV and NDT assessment ability using a three-measurement head to record sonde measurements, a wide-angle CCTV video feed and a quality hydrophone. Used for industrial, gas and water lines, it provides easy access through a variety of standard valves, hydrants and fittings while maintaining pressure on the system to provide the best possible feedback on the pipeline's performance.

The JD7 Investigator's features

The Investigator has been designed with solid features that translate into real-world capability and testing capacity. Here are some of the basics:

  • It can be used in water, gas and industrial pipelines that have a diameter of 3" or greater to provide non-destructive testing of the line.
  • It can be inserted through a fire hydrant, air valves, gate valves, 1.5" or larger pressure fittings and Quadrina fittings, making it easy to insert.
  • It can withstand pressures up to 232 PSI, providing a good range for most applications.
  • With a cable length of 328 feet, you can inspect up to 600 feet of pipe from one location, limiting the amount of time spent in transit while tracking down a troublesome leak.Bullets For the Pipe
  • The camera head provides a wide-angle lens with an illuminated fixed focal in either a 22mm or 37mm stainless steel sensor head featuring quick release connectors.
  • The sensor head features a 512Hz high-powered sonde sensor and a hydrophone sensor featuring a 240 kHz omni-directional pickup for acoustic tracking of a leak.
  • The two heads are easily interchangeable and features a mechanized tilt to make it easier to locate the exact source of your problem or to get a view from multiple angles while investigating the situation.

Situations where it works well

The Investigator works well in a wide variety of conditions to meet a range of needs. Because it is easily handled, moved and operated by one technician, it's a great choice for small departments or teams where you need to make the absolute most out of any available manpower. When you need to perform regular inspections or quickly locate a problem leak, its adaptability and easy operation makes it a great choice. Its solid design and controls based on the Panasonic Toughbook series helps deliver serious performance while standing up to the rough field conditions where maintenance technicians often work.

When Team EJP hits the field, the JD7 Investigator is the main technology we use to detect leaks at client sites. We've found it to be an effective tool that meets a wide range of needs and consider it an indispensable piece of equipment.  Please contact us today for more information on solutions to your system's problems.
