Abstract

PURPOSE: To obtain joining of pipes without requiring particularly high working accuracy and without receiving any effect of heat by forming the specific one or more steps annular bulges over the entire circumference of the end of the pipe to be joined through press fitting, on the outside circumference of said pipe.
CONSTITUTION: The end of a suction pipe 8 to be joined to, for example, the suction port 7 of a cylinder 6 of a compressor is provided with one or plural steps of annular bulges 14 formed by drawing over the entire circumference of the outside circumference thereof. The outside diameter (d1) thereof is slightly larger than the inside diameter (d0) of the suction port 7. If such suction pipe 8 is press-fitted into the suction port 7, the bulges 14 are inserted into the suction port 7 while making plastic or elastic deformation, whereby both are joined.
