ABSTRACT:
A production line for manufacturing corrugated pipe also has a calibrating basin for manufacturing smooth-walled pipe arranged between form paths of the corrugator when the paths have been separated. An extruder that normally feeds a molten plastic pipe blank to the corrugator for making corrugated pipe then feeds the pipe blank to the calibrating basin for making smooth-walled pipe, and other down-the-production-line equipment can be the same, too.
