| 成果简介 | NOVELTY - Invention relates to operation of main gas pipelines (MG). To locate the defective weld inside the protective case, the end of the protective case is opened. Then, distance from case edge to defective weld is measured. To provide access for radiographic control to the defect, a process hole is cut on the protective case with dimensions that provide installation of a magnetic film, and radiographic inspection is carried out. After radiographic inspection, the film is removed, and a conclusion is made on the degree of danger of the defective welded joint. Process hole is closed with an insulating coating. Both pits are filled with soil for reduction to initial state. USE - Measuring. ADVANTAGE - Development of method for identification of defective welded joint by radiographic method, detected by in-line technical diagnostics (ITD) inside protective case at road crossing without gas transportation stop and reduction of labour intensity of diagnostics works on defective section of main line. 2 cl, 9 dwg |
