METHOD FOR FIXING PIPE ON VESSEL AND A VESSEL WITH PIPE

摘要

PROBLEM TO BE SOLVED: To provide a method for fixing a pipe on a vessel and a vessel with a pipe improving sealing property in inserting and fixing the pipe on a wall part of the vessel to suppress manufacturing cost. SOLUTION: A part of a bottom wall part 16 is dented upward to form a dent part 17 at a center part of the bottom wall part 16 of the vessel 10 composed of conductive material and a through hole 18 is formed on the bottom wall part 16 composing the dent part 17. A cylindrical part 21 of a flow out pipe 20 composed of conductive material is inserted in the through hole 18 from inside of the vessel 10 and a flange part 2 formed on an upper end side of the cylindrical part 21 to project in a radial direction is received at a inner wall surface of the dent part 17 (bottom wall part 16) of the vessel 10. The flange part 22 of the flow out 20 and the dent part 17 of the vessel 10 are jointed over all around by resistance welding (a resistance welding part 30). A lower end edge of the flow out pipe 20 and a bottom surface of the bottom wall part 16 having the flow out pipe 20 attached are set at roughly same position (same height).
