ABSTRACT:
A spherical sealing body is to be inserted in a space defined by three of an end edge of an exhaust pipe on upstream side, a flange fixed on an outer periphery of the exhaust pipe on upstream side, and a concave spherical portion disposed on an end edge of an exhaust pipe on downstream side. The spherical sealing body comprises a wire mesh body obtained through weaving or knitting a fine metal wire, the metal mesh body has a cylindrical inner circumferential surface of the exhaust pipe on upstream side, a convex outer circumferential surface to be fitted in the concave spherical portion, and a bottom surface on large diameter side to be abutted against the flange. A refractory material is filled in meshes and clearances of a part of the wire mesh body corresponding to the convex outer circumferential face and the bottom face.
