Abstract

A process for production of large calibre plastic tube, in which a hollow thermoplastic profile of rectangular cross-section is extruded and is coiled on a drum helically with contiguous turns with adequate deformability, and in which during the coiling operation the turns are welded together at the contact surfaces by a butt-welded seam under axial pressure and heat. The hollow plastic profile is moulded in an extrusion tool to form a multi-cell profile having outer profile walls and cell-forming webs and at the same time and/or thereafter, by internal cooling of the outer profile walls and the cell-forming webs, is sized and given a design strength which is stable up to a predetermined critical pressure. The calibrated mufti-cell profile is again heated at the contact surfaces to the welding temperature of the thermoplastic material. The butt-welded seam between the turns is welded with an axial pressure below the critical pressure of the design strength. Extrusion tools for performing the process are also described.
