である。In one example, the spacing between the pipes is so small that eight people cannot fit through it, the spacing between the rows is narrow enough for a person to walk sideways, and the pipe height is IOm.
In 2001 to 2002, when a centrifugally cast austenitic #thermal steel tube with a length of 8 to 4 meters was welded, there were no abnormalities, but as time passed, corrosion and cracks in the welded parts occurred. This may be caused by creep, and it is necessary to conduct a non-destructive test using ultrasonic flaw detection to check the life of the pipe.
discloses the prior art of this 'ik standing pipe inspection device. These devices are split into two units in order to be installed on standing pipes that are installed in a row.Ultrasonic flaw detection system@The probe can be displaced by a full angle around the axis of the brass tube and can be moved up and down in the longitudinal direction of the tube. , it is connected to the higher-level masochistic machine via complicated couplings, holders, etc., and the entire m1 of this device, including the drive mechanism and utilities, is quite heavy, and it is difficult to install this heavy object in a cramped place as mentioned above. It is quite difficult to replace.
