<p>PROBLEM TO BE SOLVED: To provide a pipe joint, obtaining a large flexing angle for a short scale while attaining a small diameter, light weight, and a low cost of a product total unit by eliminating necessity for a pressure resistant reinforced fiber and a coating rubber layer, which moreover can maintain seal performance stably over a long period. SOLUTION: One first pipe member 1 constituting at least internal peripheral surface part 1A by ceramics and two second pipe members 2, 2 similarly constituting at least internal peripheral surface part 2A by ceramics are connected flexibly in a range of fitting up the fellow spherical surface parts 1C, 2C, 1C, 2C formed in an end part of these members, and ring-shaped seal materials 7, 7 are interposed between each fitting up spherical surface part 1C, 2C, 2C, 2C.</p> |
