PROBLEM TO BE SOLVED: To provide a simple means for monitoring a wear condition in a pipe line of a pipe conveyer, in particular, in a bent part where severe wear is generated. SOLUTION: In this pipe conveyer 10, the pipe line 12 is arranged to be circulated according to a conveying route, a feed port 13 and a discharge port 14 for a conveyed subject are provided in a midway of the pipe line 12, a conveying means is laid to allow circulation inside the pipe line, and a wear- resistant replaceable component is attached to the bent part of the pipe line 12. In the pipe conveyer 10, a wear loss judge-determining means is fitted to the replaceable component. In concretely saying, a wear loss judge-determining pin or a wear loss judge-determining plate is embedded as the wear loss judge- determining means in the replaceable component, the replaceable component is formed into jacket structure, an inside of the jacket is brought into a fixed pressure, and a pressure detector is attached to detect fluctuation of internal pressure in the jacket.
