1. A method for producing a glass-like carbon pipe comprising the steps of pouring a resin into a mold for forming a main portion of the pipe, said mold having a first and second opening formed therein; positioning a first mold section at said first opening of said mold for forming a tapered male threaded portion on a first end of the pipe; positioning a second mold section at said second opening of said mold for forming a tapered female threaded portion on a second end of the pipe; producing a plurality of pipe-shaped thermosetting resin molded articles in said mold, each having said male and female threaded portions by centrifugal molding; heat treating the integrated thermosetting resin molded articles to completely cure the article; carbonizing the completely cured molded articles to produce the glass-like carbon pipe; and integrating the plurality of pipe-shaped thermosetting resin molded articles by joining said male and female threaded portions of the molded articles so as to form the pipe.
