Evaluation of Torsional Guided Waves for Inspection of Service Water 

Piping 

Product 10: 1000115

Abstract 

Sector Name: Nuclear 

Document Type: Technology Review 

Cost: $250 (US dollars) 

Long-range guided wave inspection techniques are useful for obtaining a comprehensive 

view of the condition of piping systems quickly and economically, induding areas which 

are difficult to access, by launching and detecting waves from a remote accessible 

location. Piping systems in electric power plants, particularly those for the service water, 

come in various configurations; for example, aboveground or buried, accessible or 

inaccessible, and bare, coated, or lined. One way to examine these pipes from an 

accessible location is to launch ultrasonic guided waves. Although guided wave 

technology has been available for some time, its application to service water piping 

systems has been limited because of the rapid attenuation of the longitudinal wave 

mode (L) currently used when surveying pipes that are water-filled and coated. Recent 

technology developments have made it possible to launch waves of torsional (T) mode 

that appear to be better suited for service water piping applications because they are not 

affected by the presence of water. 

To evaluate the effectiveness of this new technology, its performance relative to the 

longitudinal mode was investigated experimentally in the laboratory on bare and 

bitumen-coated, 6-5/S-inch-OD, schedule 40 (0.2S-inch-wall) pipe samples. The waves 

were launched using the magnetostrictive sensor (MsS) guided wave technology 

developed at Southwest Research Institute. The investigation found that the new Twaves exhibit better performance when surveying both bare and bitumen-coated pipes 

that are water filled. For these pipes the use of low-frequency waves (10kHz or less) to 

overcome the wave attenuation caused by the coating is required. T-waves were found 

to be superior to L-waves because of (a) the lack of dispersion and associated flexibility 

in choosing operating frequency and (b) the absence of water effects on the T -wave. For 

long-range inspection of bare pipes that are empty, both L- and T-waves are equally 

suitable. The results also indicated that long-range global inspection of pipes, induding 

bitumen-coated pipes, is viable using the guided waves. For routine field implementation 

and commercialization, further development and field evaluation of the long-range 

guided wave piping inspection techniques are recommended.

Abstract 

Sector Name: Nuclear 

Document Type: Technical Report 

In May 2007, EPRI conducted a Nuclear Power Plants Piping Integrity Workshop in 

which the integrity of buried pipes was identified as one of the top priorities. In October 

2007, EPRI conducted a follow-up Workshop on Buried Pipe attended by more than 40 

representatives from utilities and EPRI. At the conclusion of the October 2007 meeting, 

the utility attendees unanimously recommended that EPRI sponsor the development of a 

recommendations document for buried pipe to help plant engineers prevent and mitigate 

degradation and leaks in buried pipes. This report has been prepared to address that 

need.

Nondestructive Evaluation: Further Developments of Guided Wave

Abstract 

Sector Name: Nuclear 

Document Type: Technical Update 

Cost: $15,000 (US dollars) 

Guided wave examination is a relatively new nondestructive examination (NDE) 

technology that has some significant advantages over more traditional NDE technology. 

Guided waves can travel significant distances within components such as piping, tubing, 

plate, cable, or rod . The technology can be used to remotely examine relatively large 

inspection volumes quickly. Despite these benefits, guided wave examination has not 

been widely applied in the nuclear industry due in part to the complexity of applying the 

technology and interpreting the results. However, recent industry inspection needs such 

as examination of buried pipe cannot be met with traditional NOE technology_

For corroded piping in low-temperature systems, such as service water systems in 

nuclear power plants, replacement of carbon steel pipe with high-density polyethylene 

(HOPE) pipe is a cost-effective solution. The results documented in this report are 

intended to support development of the American Society of Mechanical Engineers 

(ASME) Boiler and Pressure Vessel Code Case N-75S. This case supports use of HOPE 

pipe in buried Section III, Division 1, safety-related piping applications. This document

445474C HOPE material. Testing methodology is similar to the methodology used in 

previous testing of cell classification 345464C HOPE material, covered in EPRI Report 

1013479. This report is freestanding and, therefore, the methodology and supporting 

theory detailed in Report 1013479 is restated.

This report makes recommendations for improving the safety and reliability of buried 

pipe. Since most buried pipe is constructed of carbon steel, it is the report's main focus. 

Other less commonly used materials, including reinforced concrete, cast iron, copper 

nickel, aluminum, and fiber-reinforced plastics, are discussed to a lesser extent. The 

report's recommendations will be presented to appropriate organizations for funding 

consideration in 2008 and beyond . Some recommendations apply to utilities; in addition 

to this report, these recommendations will be provided to members through 

presentations at related meetings and user groups.
