Abstract
PURPOSE: To tightly fasten a shape tube and an internal tube and internally line the former by giving a relative temp. difference to the shape tube and the internal tube around the time for insertion, inserting the inside tube into the shape tube, increasing the opposing space, exerting tube expanding force to the inside of the internal tube thereby plastically expanding the same then giving the relative temperatures opposite from these of the above-mentioned temperatures to the shape tube and the internal tube.
CONSTITUTION: An internal tube 2 for lining made of stainless steel is inserted into the internally closed inside circumferential surface of the outside tube 1 of a shape made of, for example, carbon steel, and these are bent to a prescribed crooked shape. Thereupon, the outside tube 1 is heated with a coil heater around the outside circumference of the outside tube 1 and cooling water is flowed in the tube 2 to cool the tube 2, whereby the opposing space of the outside tube 1 and the tube 2 is increased. Thence, the tube 2 is pressed with the water therein and is thereby applied with tube expanding force, by which the tube 2 is plastically expanded and is closely adhered to the closed inside circumferential surface of the outside tube 1; thereafter, the liquid is removed from the inside of the tube 2 and water is jetted to the outside of the outside tube 1, then the outside tube 1 coolds and the tube 2 heats up and both fasten to each other tightly. It is equall to peform the heating of the tube 1 and the cooling of the tube 2 before the insertion.
