Non-Destructive Method For Repairing Pipes

One of the newest methods for repairing pipes is the use of a Non-Destructive Testing (NDT) method. This non-destructive testing method uses ultrasound to check for material flaws that are open to the surface. This method produces a visual indication of a flaw. This method is most often used to inspect welds, but it can also be used to check pipes, castings, bars, and plates.

A MAC system can evaluate the condition of pipe and embedment without causing any damage to the pipe or to its surroundings. The MAC system was developed by the Institute for Underground Infrastructure and Eau de Paris, which modified the technique for smaller diameter pipes. The instrumentation and control technology used in a MAC inspection can detect internal flaws. A MAC method can detect these defects without affecting the integrity of a pipe.


MAC systems are capable of identifying the position and condition of the pipe. It is able to detect damage and determine the condition of the embedded materials in a sewer. The MAC method is primarily used in large sewers, such as interceptor sewers. Failure of the fabric in a large sewer can cause leaks and deterioration. It is possible to detect a failing pipe’s fabric by using a MAC system.

A MAC system can be applied to large pipelines for structural assessment and rehabilitation. The MAC system provides dependable data for the selection of a rehabilitation method. For example, large interceptor sewers need rehabilitation to maintain their hydraulic capacity, leak-tightness, and stability. The failure of the fabric can lead to serious problems. And a MAC system is ideal for these problems. These specialized tools can be used to diagnose the condition of any pipe or embedment.

plumbers are capable of detecting the condition of a pipe, as well as its embedding. MAC is most useful for large interceptor sewers that have an extremely high hydraulic capacity and need to be leak-tight. The MAC system also helps determine the condition of smaller diameter pipes. It can also detect the presence of corrosion and failure of reinforcing wires. These MAC techniques provide reliable data for structural assessment and rehabilitation of large pipe networks.

CD tools direct ultrasonic waves into a pipeline’s wall to determine the condition of its welds and other internal components. The tools use transducers mounted on a flexible carriage at the rear of the tool. These transducers generate pulses and reflect them. Depending on the size of the pipe, up to ten simultaneous readings can be taken from different features and flaws.
