Abstract

The extruded tubular material, particularly cross-linked polyethylene passes over the mandrel at 180 degrees C as it emerges from the extruder, to be expanded by 40%, the end of the mandrel decreasing by 1.5% diameter for the tubing to be cooled in the expanded condition. The purpose is to prevent damage or distortion to the material and altering the cross-linked condition by pulling it over a mandrel.
