PURPOSE:To make it possible to obtain a lining excellent in adherence and with uniform thickness by eliminating the influence of condensate by a method wherein a draining means of the condensate is provided on each closing jig, which is attached at the end of a pipe, of the end of a tube. CONSTITUTION:A draining means 10 of condensate 9, which accumulates in a tube 2, is provided on each closing jig 3, which is attached at the end of a pipe 1, of the end of the tube, so as to continuously discharge the condensate 9, which is formed through the condensation of vapor, outside the pipe in order to heat the tube with the vapor. Because no heat is absorbed by the condensate by continuously discharging the condensate outside the pipe under the heat and pressure of the tube, nonuniformities of the temperature in the pipe and the elongation of the tube are eliminated and tube lining which ensures the uniformities in thickness and in adherence over the whole periphery of the pipe, is made possible. |
