PURPOSE:To facilitate the insertion work by a method wherein a container is sealed after pipe-expanding liquid has been charged in said container of a heat pipe and inserted in a hollow metal pipe and, after that, the pipe-expanding liquid is heated up to the predetermined temperature. CONSTITUTION:A container 1 is sealed at its temporary sealing part 8 after pipe-expanding liquid 4-1 has been charged in the container 1 of a heat pipe. After that, the container 1 is inserted in a hollow metal pipe 5 and then the pipe-expanding liquid 4-1 is heated up to the predetermined temperature so as to expand the container 1 in order for the container 1 to be inserted to the hollow metal pipe 5. Due to the method as mentioned above, the similar adherence to the shrinkage fit between metals can be obtained with a simple operation and yet without employing any special device. |
