<p>PURPOSE:To make connection of pipes surely during and after work execution by providing a detecting part, actuated by the pipe inserted to a socket joint, in it and detecting a pipe connection condition by an output of the detecting part. CONSTITUTION:An electrical contact 6 is embedded in a socket joint 1 so as to be closed by pressing of the end of a pipe 2 fitted into the socket joint 1. The electrical contact 6 is housed in a vertical direction inside a partitioning inner flange 1a for pipe stopping of the socket joint 1, when an end face of the pipe 2, inserted into the socket joint 1, collides with this inner flange 1a, the electrical contact 6 is pressed from the outside and closed. An electric signal is confirmed by drawing out the electrical contact 6 outside the pipe 2 by a lead wire or the like. As a result, whether the pipe is mounted in an accurate position and angle or not can be easily confirmed during execution. While inspection can be attained to a minimum limit because the pipe can be surely connected simultaneously with completion of the execution.</p> |
