ABSTRACT:
There has been provided a delivery system for conditioning molten thermo-plastic material, wherein a first pipe member, having an inlet at one end adapted to receive the material and an outlet at an opposite end for delivering the material therefrom at a desired homogeneity is coupled at its inlet end to a furnace. An insulated shell structure, having at least one fluid inlet and outlet therein, is located concentrically about the first pipe member and defines a closed insulated space thereabout. The shell is adapted to receive heat exchange fluid for circulation from the inlet to the outlet in said closed space for removing heat from the thermo-plastic material flowing through the pipe member. Means is provided for shielding inside surfaces of space between the shell and the pipe member from deleterious ambient including a purge fluid which may act alone as the heat exchange fluid.
