Claims

[Scope of utility model registration request]

In a pipe joint that connects a union nut to a union adapter welded to the end of a pipe, a regular hexagonal surface with the same dimensions as the union adapter or rubber hose fitting used as a pair is formed on the outer circumferential surface of the union nut. ,
The outer circumference of the union adapter, from the middle of the outer peripheral surface that does not fit into the union nut to the welded end, is formed into a cylindrical surface with a diameter that is approximately equal to or greater than the diagonal distance of the regular hexagon of the union nut. A piping joint characterized in that the remaining outer peripheral surface is formed with at least 2,000 opposing faces having the same dimensions as the width across opposing faces of the regular hexagon of the union nut.
