ABSTRACT:
A steel eyejoint for receiving the end of a pipe and attaching itself to a frame is made of a pair of half members. Each half member consists of a flat head section formed with an attaching hole and a tail section extending from the head section. The head section has an annular flow path defined thereinside which is in communication with the attaching hole and with the inside of the tail section. An opening edge of one half member is partly overlapped with that of the other. The two half members are brazed together along the overlap line between the opening edges.
