Abstract
A method for producing a biaxially oriented tube from thermoplastic material, wherein a tube 5 in preform condition is extruded from thermoplastic material using an extruder which is provided with an extruder die head having an inner die member, the inner die member forming a lumen in the tube in preform condition, wherein the tube in preform condition is subjected to a temperature conditioning by one or more tempering devices so that a tempered tube is obtained having an orientation temperature which is suitable for the 0 thermoplastic material, and wherein use is made of an expansion device in the lumen downstream of the extruder, said expansion device including: - a non-deformable expansion part having a gradually increasing diameter to a maximum diameter at a downstream end thereof, which expansion part is contacted by the tube and exerts an expanding force on the tube so as to bring about expansion of the 5 tempered tube in circumferential direction, - a run-off part adjoining the expansion part at the downstream end thereof, wherein the method includes drawing the tempered tube over the expansion device using a drawing device which is arranged downstream of the expansion device and acts on the tube, in such a manner that said tube is drawn over the expansion device and transformed from a 0 tube in preform condition into a biaxially oriented tube with thermoplastic material being oriented in axial direction and in circumferential direction, wherein said biaxially oriented tube is cooled, and the run-off part of the expansion device has a reduced diameter section having a smaller diameter than the maximum diameter of the expansion part, 25 wherein use is made of at least one outer diameter ring member that is arranged at the location of the reduced diameter section of the run-off part of the expansion device and around said reduced diameter section, and wherein the oriented tube passes through the at least one outer diameter ring member while being in contact with said at least one outer diameter ring member, the outer 30 diameter ring member and the reduced diameter section being dimensioned such that seizing of the oriented tube between the run-off part and the at least one outer diameter ring member is avoided, the inside of the oriented tube being radially spaced from the reduced diameter section, and in that the oriented tube is cooled externally while passing over the run-off part by 35 a first external cooling device.
