Abstract

PURPOSE: To prevent the spherical portion of the outer surface from breaking by a structure comprising a ring-shaped reinforcer made of metallic mesh; a mixture of a solid lubricant packed into the reinforcer and a metallic fiber; and an expansive graphite sheet that forms a sealing layer on the spherical portion of the outer surface, etc. CONSTITUTION: Seal body 10, which has through hole 11 in its inner face and spherical portion 12 of the outer surface, comprises a ring-shaped reinforcer 1' made of metallic mesh; a mixture of a solid lubricant and a metal fiber with a diameter of 10 to 200 μm and a length of 100 to 800 μm; and an expansive graphite sheet so as to form a seal body for a spherical pipe joint. Further, the mesh of reinforcer 1' is filled with graphite, molybdenum disulfide or the like. In addition, the expansive graphite sheet covers reinforcer 1 and forms a sealing layer 13 for integrally sealing the through hole 11 in the inner face and the spherical portion 12 of the outer surface. As a consequence, failure and defect of the tip of the seal body does not occur. Further, the sealing effect against the leakage of gas can be maintained during a long period of time.
