Abstract

Process for the production of tubes of thermoplastic material, characterized in that it comprises extrusion molding a thermoplastic material consisting at least predominantly of a propylene polymer, of high molecular weight, linear and crystalline using an extrusion die having an annular opening, mounted in an extruder maintained at a lower temperature than said matrix is maintained, and the thermoplastic material leaves the annular opening at a temperature of up to 100ºC above its melting point.
