<p><P>PROBLEM TO BE SOLVED: To provide a light-weight flexible pipe joint made of titanium having excellent durability against chemicals and sea water, flexibility, expansion property, and torsion absorptivity. <P>SOLUTION: An end of a flexible metallic pipe 20 presses and crashes in an axial direction an angular part of a pipe wall to form a flange shape locking part 21. A coupling member 24 of a flange 22 is held between the flange shape locking part 21 and the angular part 25, and a flange body 23 of the flange 22 is prevented from being disengaged by the coupling member 24. The pipe wall of the flexible metallic pipe 20 is made of titanium. An annular member 26 of titanium having a packing seat surface 27 is overlapped to the flange shape locking part 21, whereby padding of a welding 34 is performed over an outer peripheral part of the flange shape locking part 21 and an outer peripheral part of the annular member 26. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
