IPC: F16L55/00
Filed: 2001-08-27
Abstract: PROBLEM TO BE SOLVED: To enable an article transportation facility, such as the pneumatic powder feeding facility, etc., of a converter to surely prevent the occurrence of a secondary accident or disaster caused by the leakage of a transported article or fluid by surely detecting in an early stage such a deficit as the perforation of a transport pipeline, such as a pneumatic pipeline, liquid feed pipeline, etc., caused by wear, corrosion, etc., by means of a relatively simple inexpensive device. SOLUTION: Double-pipe abnormality detectors 20 for transportation pipeline are installed to the transporting direction changing sections 5a, 5b, and 5c which are the specific wearing sections of the pneumatic pipeline 5 of the pneumatic powder feeding facility. The pressure P2 between the inner pipe 21 and outer pipe 22 of each detector 20 is preset to meet P3 >P2 >P1 (wherein, P3 is the internal pressure of the pipeline 5 during pneumatic feeding and P1 is the internal pressure of the pipeline 5 while the pneumatic feeding is stopped) and always monitored.
