Abstract

A cylindrical nipple is firmly attached at one end by soldering or welding to a specific point on one of the pipes, the other end of the nipple is shaped so as to permit connection to the other pipe by means of an external compression ring. The nipple can be used as a branch union, in which case it is welded or soldered at one end to the external periphery so that the edge of the nipple around its whole circumference is in close contact with the pipe, or as a straight union, in which case one end of the nipple is welded or soldered to the inside or outside of the pipe end to form a projecting sleeve.
