Abstract

PURPOSE: To make the pipe expansion for the thin walled stainless steel pipe possible to be easily carried and to carry out surely and quickly the joining work for this pipe with the pipe joint, by specifically arranging the driver for holding and turning round the pipe expander, the ring holder supporting holder vise, and the pipe holding pipe vise.
CONSTITUTION: Two ears 21 of the ring holder 7, possessing the round hole 19 fittable to the diameter of the steel pipe B to be laid in the line, are set to the holder vise 5, and the tapered mandrel 10 of the pipe expander 8 is fixed to the chuck 12. The positioner 15 is turned round, and the plunger 16 fittable to the steel pipe diameter is selected, and the ring A is inserted into the hole 19 and is tightened. The steel pipe B is inserted into the vise 6, and the terminal end of the pipe B is inserted into the ring A and is fixed. Hereupon, the vise 6 is suitably travelled along the rail 3. Next, the driver 4 is similarly travelled toward the vise 5, the expander 8 is inserted into the steel pipe's terminal end, and the mandrel 10 is turned round, and besides, the driver 4 is automatically moved forward toward the vise 5. Hereby, the steel pipe's terminal end is expanded, and its outer surface penetrates into the saw- tooth type groove C of the ring A and is press-welded.
