Document Type and Number:
WIPO Patent Application WO/2013/105181
Kind Code:
A1
Abstract:
[Solution] In the spherical exhaust pipe joint (X), a spherical band-shaped sealing body (36) is fitted to and fixed on a pipe end (42). The spherical band-shaped sealing body (36) abuts against a flange (43) and is seated thereon. A radius-enlarging section (47) formed from an Fe-Cr stainless steel containing 17.00-19.00 mass% of Cr is fastened on the downstream-side exhaust pipe (44), and the inner surface (48) of the concave spherical surface (45) is in sliding contact with a composite surface (40) wherein a surface (38) obtained from a reinforcing material (5) in the outer surface (37) of the outer layer (35) of the spherical band-shaped sealing body (36) and a surface (39) obtained from a solid lubricant are intermixed.
