Page 18: Guidance To Effective Acoustic Leak Detection
When a leak is produced in a metallic pipe the leak noise will transmit well through the pipe. It does not travel so well through a plastic pipe. This means that a leak Xmic 24/01/05 MAN-095-0001 Revision B... - Page 19 If there are no accessible contact points or if the pipe is of non-metallic material, use the microphone foot for listening, placing the foot over the pipe route in the area of the suspected leak. Move along the pipe route listening at each accessible pipefitting Xmic 24/01/05 MAN-095-0001 Revision B...
