ABSTRACT:
A device for heating plastic pipe comprising a hollow annular housing with an inner surface including a plurality of dispersed perforations, and an inlet conduit attached to the housing. The inlet conduit is adapted to be connected to a source of heated air so the air can circulate through the device. In one embodiment, the annular housing is elongated and the perforations are uniformly dispersed around the inner surface. The inlet conduit is attached to the housing's midpoint and the inlet conduit and housing are made from sheet metal. The inlet conduit of the device is of such a diameter that the device can be slideably received on an automobile's exhaust pipe so the heated exhaust can circulate through the device in order to heat the plastic pipe.
