Pipe clamping device

Abstract

A pipe clamping device that clamps a first pipe and a second pipe each other. The pipe clamping device comprises an annular case with central opening into which the first pipe and the second pipe are inserted; a tightening member movable between a tightening location where the tightening member tightens outer circumferential surface of the first pipe and the second pipe and a disengagement location where the tightening member does not impose pressure on the outer circumferential surface of the first pipe and the second pipe; and a stopper restricting radial movement of the tightening member such that diameter of the tightening member at the disengagement location does not extend beyond a predetermined number, the stopper being prepared in the annular case. The present disclosure provides easy clamping of pipes since the tightening member at a disengagement location has a predetermined diameter by the stopper of the case.
