Abstract

PURPOSE:To fit inside and outside tubes with uniform precision, by inserting the inside tube into the outside tube and flowing a cooling liquid to the inside tube before the work for expanding the diameter of the inside tube while agitating the cooling liquid cooling the inside tube uniformly to reduce the diameter and extending diameters of inside and outside diameters as one body. CONSTITUTION:An inside tube 2 is inserted to an outside tube 1, and cooling water supplying and discharging tubes 5 and 6 are fitted and sealed to ends 2' and 2'' of the inside tube 2. Turbin type fins 10 and 10 which turn the flow of cooling water 7 in the same direction and propellers 12 and 12 motors which are provided coaxially inside tubes 5 and 6 to flow cooling water are provided at ends of tubes 5 and 6. Propellers 12 and 12 are operaed to supply cooling water, and simultaneously, and electric heater 4 is heated and is brought into contact with the outside tube 1 to heat the outside tube 1, and the inside tube 2 is cooled by cooling water 7. Cooling water 7 is turned and flowed spirally by the supplying function of propellers 12 and 12 and the turning force applying function of fins 10 and 10. Consequently, the temperature distribution is not deflected in the circumferential direction, and the inside tube 2 is cooled uniformly to reduce the diameter without forming a staying space above even if vapor exists. Next, the inside diameter 2 is expanded and is brought into contact with the inside face of the outside tube 1, and these tubes are expanded as one body and are fitted and joined tightly uniformly.
