Abstract:

The objective of this project is to build a pre-commercial device, improve its performance to detect multiple buried pipes, and evaluate the pre-commercial device at utility sites. In the past, Gas Technology Institute (GTI) and SoniVerse Inc. (SVI) with support from Operations Technology Development, NFP (OTD) have developed an acoustic-technology-based technology to detect buried natural gas pipes, with emphasis on detecting buried polyethylene (PE) pipes. The concept is to send the acoustic signal into the ground and detect the reflected signal from the pipe at ground level. The device has been referred to as Emulator, and was successfully tested in the laboratory and at several utility locations under a variety of field conditions to detect both metal and PE pipes buried up to 5 feet. The Emulator consists of a laptop computer, off-the-shelf data acquisition module, high power class D amplifier, deep cycle car battery, and exchangeable sensor modules. The work conducted under this U.S. Department of Transportation, Pipeline and Hazardous Materials Safety Administration (DOT/PHMSA) project improved/developed and built an integrated, hand-held device – pre-commercial unit – to detect buried pipes. The integrated device was successfully tested at several field sites. The detection of buried natural gas pipes, especially PE pipe, will assist the gas industry and pipe locator companies to locate pipes before excavations/construction. This will reduce the third party damages to the underground utilities, increase safety of the natural gas distribution system, and reduce gas industry operating costs.
