を特徴とする長尺パイプ製造装置。 The lower mold is provided with a forming table that supports a metal tape to be formed, and the forming table is arranged as a pair on the forming table so that the distance between the tip ends thereof becomes gradually narrower in a symmetrical manner. and a pair of molding members for forming a tube by gradually rolling the metal tape from both edges in the width direction, and the upper mold is configured to roll the metal tape toward the forming table between the two molding members. The metal tape is formed into a tube using a triangular former configured to have a tapered shape that acts as a pressing force, and then the joints of the formed metal tape are welded with a welding torch to form a long length. In a long pipe manufacturing apparatus for manufacturing pipes, a preforming roll device is provided at a position before the metal tape is put into the triangular former to round and preform both edges in the width direction of the metal tape with upper and lower edge rolls, The long pipe is characterized in that the maximum width of the surface of the upper die in contact with the metal tape is selected to be smaller than the width of the metal tape excluding the width of the portion of the metal tape where both edges are formed by the edge rolls. Manufacturing equipment.
