- 20 - ABSTRACT OF THE DISCLOSURE An extrusion die, particularly for double-walled thermoplastic pipes, includes an extrusion head, a nozzle, two concentric hollow mandrels carrying die lips and an additional cooling mandrel. The lips have threaded adjusting members to vary the sizes of the die gaps, the lips for the inner wall being provided with electrical heaters. The concentric mandrels have a spider with members for its radial adjustment. The cooling mandrel has substantially annular channels for a coolant, communicating with each other by means of a sharply skewed opening and combined into a number of sections to control intensity of heat exchange.
