Abstract
PURPOSE: To form a double-bend pipe without dividing and reuniting its outer pipe, by applying a bending work to a double blank pipe after filling up the gap between the outer pipe and inner pipe and the inside of the inner pipe, with a restraining packing medium.
CONSTITUTION: For manufacturing a jacketted line pipe, an inner pipe 1 is inserted into an outer pipe 2, and whose both ends are closed with flat plates 3 provided with a hole respectively. A packing medium 4 such as paraffin, in a viscous liquid state as a result of heating, is introduced 6 or fed under pressure through the hole of the plate 3 on one side, while purging 7 the inner air through the hole of another plate 3. The packing medium 4 is solidified by cooling, and then, a prescribed bending work is applied to the blank pipe. After completing the bending work, the whole blank pipe is heated and steam 8 is injected through the hole of the plate 3; hereby, the packing medium 4 is steamed off at 9 of the pipe, and a double-bend pipe is obtained.
