| Abstract: | Effective detection of the corrosion and deposit inside insulated pipes is a problem that must be solved in petroleum and chemical plants. Radiographic testing is an effective way, but complicated data processing is needed, such as quick and effective data extraction. The development of radiographic testing of insulated pipes and the ways of data extraction, as well as some unsolved problems and effective testing technologies are described. |
