FLEXIBLE-PIPE JOINT
Document Type and Number:
WIPO Patent Application WO/2023/120520
Kind Code:
A1
Abstract:
Provided is a flexible-pipe joint that makes it possible to eliminate marking work by a builder, and that also makes it possible to easily identify any building defects. The flexible-pipe joint is a pipe joint 1 for connecting a bellows-shaped flexible pipe in which a plurality of peaks and troughs are alternately arranged in an axial direction. The pipe joint is a joint configured so that when the flexible pipe is inserted into the joint from one end section up to a prescribed location, the flexible pipe is thereby sealed and prevented from being dislodged. On one end section on the inner circumferential surface of the pipe joint, a mark assigning portion 9 is present which comes into contact with a cover body for covering the flexible pipe when the flexible pipe is inserted, and thus assigns a mark onto the cover body.
