Abstract

PURPOSE:To prevent damages and considerably reduce welding time by cooling the welding portion while pouring water into the vinyl-chloride-lined steel pipe at the time of welding a flange to the pipe end of the vinyl-chloride-lined steel pipe. CONSTITUTION:A wooden plug 5 is mounted to one end 9 of a vinyl-chloride-lined steel pipe 1 and the pipe 1 is inclined so as to position its end 9 downward and is supported rotatably to a pipe support base 4. Next, in this state, a flange 2 is tentatively mounted to the end 9 and while water 8 is being poured into the pipe 1 from a hose 7, the welding portion is cooled. The flange 2 is welded while the pipe 1 is being rotated. Even if the inner vinyl chloride pipe 1' is heated by this welding, it is cooled by the water 8 and the water 8 is flowed out through water-flow holes 6. In addition, the water is constantly poured from the hose 7, and therefore no damages are given to the pipe 1'.
