摘要

The invention relates to an adjustable pipe bend which has at least two parts (10,10a) joined by flanges (12,12a) which incorporate an electrical fusion element in the form of a plastic annular disc (15) with a heater wire (16) located at or adjacent both surfaces of the disc (15). A number of embodiments of the invention illustrate different adjustable bends, the arrangement being that the bend is adjusted to a required position and then the heater wire (16) has a voltage applied to it to produce a heating current which causes the plastic annular disc (15) and adjacent plastic faces of the flanges (12,12a) to melt sufficiently to cause fusion between the two parts (10,10a) of the pipe.
