WIPO Patent Application WO/2019/021821
Kind Code:

Abstract:
Provided is a mechanical pipe joint with which bending fracture of a pipe to be connected can be effectively prevented even when subjected to bending deformation. Also provided is a pipe joint structure with which pipes to be connected can be connected with a simple structure by using such a pipe joint. The pipe joint is configured so as to seal between an outside pipe body (12), an inside pipe body (14) that is coaxially inserted inside the outside pipe body (12) and that provides between itself and the inner surface of the outside pipe body a gap into which a pipe to be connected (32) is inserted, and the pipe to be connected (32) that is inserted by means of a seal means arranged between the outside pipe body (12) and the inside pipe body (14), where the outside pipe body (12), the pipe to be connected (32), and the inside pipe body (14) are secured by crimping. The outside pipe body (12) protrudes farther outward in the axial direction than the ends of the inside pipe body (14).
