Abstract
A refrigerant piping unit includes a pipe and a joint coupled to the pipe. The pipe includes a main section, an end section and a bent section between the main section and the end section. The end section includes a flange portion adjacent to the bent section and a thick end portion opposite to the bent portion with respect to the flange portion in an axial direction. The flange portion is expanded in a radially outward direction and is engaged with the joint. The thick end portion is expanded in the radially outward direction and has a thickness greater than a thickness of the main section. The thick end portion has a groove on its outer surface. The end section has a flat inner surface extending continuously from an inner surface of the bent section throughout inside of the flange portion and the thick end portion.
