ABSTRACT:
With a metal pipe comprising a double-pipe section connected with a single-pipe section, the double-pipe section in which dead water remains has a lesser degree of heat transfer effect so that it cannot be heated to a steady state. According to the present invention, firstly the single-pipe section starts to be heated and after a predetermined time the double-pipe section starts to be heated. After a predetermined time, the heating of the double-pipe section is stopped and then after a predetermined time the heating of the single-pipe section is stopped, whereby improvement of stresses in the inner wall surface of the pipe can be attained.
