Methods, systems, and computer-readable storage media for accurate time delay estimation using coherent averaging. A plurality of out-of-bracket acoustical impulses are generated in a pipe segment of a fluid distribution system. Signal data representing the acoustical impulses sensed at two locations along the pipe segment are recorded. Precise timings for the generation of the acoustical impulses are obtained, and the acoustical impulses in the signal data recorded from the first location are averaged based on the precise timings to produce a near- sensor average impulse. Similarly, the acoustical impulses in the signal data recorded from the second location are averaged based on the same precise timings to produce a far-sensor average impulse. A time delay between arrival of the plurality of out-of-bracket acoustical impulses at the first and second locations is estimated from the timing of the near-sensor average impulse and the far- sensor average impulse.

A method of detecting leakage in a force main involves placing at least two spaced sensors on the force main. Liquid is pumped through the pipe by means of a pump. The pump is shut down for an interval of time, and during the period following pump shutdown while negative pressure is present in the pipe, signals are generated at the sensors due to noise or vibration resulting from fluid being drawn into the pipe. The position of a leak in the pipe is determined by correlating the leak noise signals generated while the pipe is under negative pressure. Alternatively, the invention can be applied to a pressurized pipe, in which case conditions of negative pressure can be deliberatively created for a period to draw in fluid from the outside.

The present invention is a plug system having a plug for insertion into a pipeline, wherein the plug system is insertable via a fitting attached to the pipeline. A pre-drilled aperture of the pipeline positioned normal to the cylindrically-shaped pipeline may interfere with a pig traveling through the pipeline. In one embodiment, the plug includes two coaxial cylindrical portions. A first cylindrical portion has a diameter greater than the aperture diameter, while the second cylindrical portion has a diameter less than the aperture diameter. Additionally the plug defines a hole that is oriented perpendicular to an axis of the cylindrical portions, wherein the diameter of the hole is approximately the size of inside diameter of the pipe. The plug has a retaining member to stabilize the plug system. When the plug is installed in the pipe it permit a pig to flow freely, thereby eliminating pigging hazards.

To perform a non-destructive condition assessment of a pipe carrying a fluid, an actual value representative of the propagation velocity of an acoustic disturbance propagating between two longitudinally separated points on the pipe is determined. A corresponding predicted value for the propagation velocity is computed as a function of at least one wall thickness parameter of the pipe by using a theoretical model for the propagation of acoustic waves in the pipe that assumes said pipe has a finite wall thickness with a predetermined circumferential thickness profile. The wall thickness parameter is then computed by matching the actual value with the predicted value, for example, by substituting the actual value in a formula predicting the theoretical value.
