Piping system

摘要

A piping system (100) includes a flare machining mechanism and a screw machining mechanism that machines the ends of pipes (22) by cold-pressed formation. The flare machining mechanism flares the ends of pipes (22) outward and the screw machining mechanism machines the outside of the pipe end into a convex screw and the inside of the pipe end into a concave screw are provided on the same rotor mechanism (1) and the same chuck. The piping system (100) is configured to execute flare machining and screw machining of the end of the pipe by exchanging the flare machining head (15) and the screw machining head (16).
