ABSTRACT:
A method for producing a glass-like carbon pipe is provided. The method comprises the steps of producing a plurality of thermosetting resin molded articles by centrifugal molding, said molded articles each having the shape of the sections of a pipe divided in the longitudinal direction and each provided with threaded or fitting portions; integrating these molded articles by joining at the threaded or fitting portions; and carbonizing the joined pipe to thereby produce a glass-like carbon pipe. This method is capable of producing a straight or bent pipe with excellent mechanical strength and gas sealability at the joint, and this method enables production of a pipe at a low cost since no machining is required for providing the threaded or fitting portions.
