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.
