Überprüfung von Wasserleitungen mit akustischer Technologie in Norwegen

Determining the remaining useful life of water pipes can be challenging. A Norwegian water company recently tested a new method based on the use of Echologics' already proven acoustic technology. The field tests are intended to help the water supply company to facilitate the planning of the maintenance and rehabilitation of the water network.

Sending sound waves through water pipes to locate leaks is a well-known approach because the country's water and sanitation authorities are already using this method. The same technology can also be used to determine the wall thickness of underground water pipes. The results of this test can be used to estimate the remaining useful life of the pipe. The method is to send sound waves through the water pipe and sense the speed of sound to determine the thickness of the pipe wall. The method can be applied to a variety of pipe materials and has been demonstrated in the field tests on pipes made of cast iron and asbestos cement.
