“…In pipe applications, GUWs may propagate along the pipe's longitudinal direction and excite the entire cross-section [19,63,64], and therefore GUWs are effective when large inspection coverage is required. The advantage of GUW inspection is its ability to probe long lengths of the pipe, locating cracks and notches from few monitoring points, while providing full coverage of the pipe's cross-section [63][64][65][66]. In addition, by combining the methodology with opportune signal processing, the method is feasible for the permanent monitoring of the pipe's health.…”

pipe networks assure the transportation of primary commodities such as water, oil, and natural gas. The quantitative and early detection of defects in pipes is critical in order to avoid severe consequences. As a result of high-profile accidents and economic downturn, research and development in the area of pipeline inspection has focused mainly on gas and oil pipelines. Due to the low cost of water, the development of nondestructive inspection (NDI) and structural health monitoring (SHM) technologies for fresh water mains and sewers has received the least attention. Moreover, the technical challenges associated with the practical deployment of monitoring system demand synergistic interaction across several disciplines, which may limit the transition from laboratory to real structures. This paper presents an overview of the most used NDI/SHM technologies for freshwater pipes and sewers. The challenges that said infrastructures pose with respect to oil and natural gas pipeline networks will be discussed. Finally, the methodologies that can be translated into SHM approaches are highlighted.

“…Advantages of using guided waves include ability to perform inspection over long distances, usefulness in inaccessible areas and lack of necessity to remove extensive amount of pipe insulation. Use of long range guided waves for piping inspection is reported by Cawley (1996, 1997), Pei et (1996), Rose @J. (1996), Lowe et (1998), Bray a (1998), Alleyne et (2000) and Wassink et (2000).…”

“…The system can detect corrosion defects causing 5-10% loss of cross sectional area at a particular axial location. Another system (Rose et, 1996) uses a multi-element comb transducer. Generation of guided waves with different modes and frequencies by a comb transducer could be used to vary the sensitivity to different defect types and sizes.…”

SUMMARYNon-destructive testing is a key component of optimized plant inspection and maintenance programs.Risk based inspection, condition based maintenance and reliability centered maintenance systems all require detection, location and sizing of defects or flaws by non-destructive methods. Internal damage of geothermal piping by corrosion and erosion-corrosion is an ongoing problem requiring inspection and subsequent maintenance decisions to ensure safe and reliable performance. Conventional manual ultrasonic testing to determine remaining wall thickness has major limitations, particularly when damage is of a random and localized nature. Therefore, it is necessary to explore alternative non-destructive methods that offer potential benefits in terms of accurate quantification of size, shape and location of damage, probability of detection, ability to use on-line over long ranges, and economics. A review of non-destructive methods and their applicability to geothermal piping was performed. Based on this, ongoing research will concentrate on long range guided wave and dynamic methods.

“…Ultrasonic lamb wave are being used for interpretation of plates [1], multilayer structures [2], pipes [3], rails [4], elbows [5], honeycomb structures [6], composite plates [2], and so on; also for materials characterization [7] (mainly elastic modules and stiffness constants). It can be used successfully for insulated [8] and coated pipes [9] as well as for inspection of objects under the water [10].…”

“…The sensitivity of lamb wave to defects is greater than common ultrasonic method [11]. Lamb wave inspection is fast and its cost is so lower than common ultrasonic techniques or other inspection methods [3,10,11]. Angle probes, electromagnetic acoustic transducers [11], comb probe [12], immersion method [13] and laser ultrasonic technique [14] may be used for ultrasonic lamb wave testing.…”
