PURPOSE: A connection method of a supply and drain pipe integrated with a one-end collar is provided to simultaneously perform melting and integral combination by using a pipe melting part and melting connecting part to an one-end collar melting device. CONSTITUTION: A connection method of a supply and drain pipe integrated with a one-end collar is as follows. A fuse connection part(22) is located on one side of a separate sill(23) and is heated in the inside diameter fusion part in 190~240°C for 8~10 minutes. A pipe fusion part(11) is located at one end of the supply and drain pipe. The pipe fusion part is heated along with the fuse connection part in the external diameter fusing part in 190~240°C for 8~10 minutes. The fuse connection part and pipe fusion part keep concentricity to be integrally fused.
