Abstract

Oppfinnelsen vedrører en fremgangsmåte og anordning for avkjøling av et ekstrudert termoplastrør (1), ved å lede et gassformig kjølemedium tangensielt mot den innvendige flaten av termoplastrøret (1) langs hele dens omkrets, hvormed det innvendige av termoplastrøret (1) deles opp ved hjelp av et beskyttende rør (8) til en utvendig ringformet strømningskanal (9) for avkjølingsmediet langs den innvendige flaten av termoplastrøret (1), og en sentrisk returkanal (10) gjennom hvilken en del av kjølemediet er ment å bli suget tilbake under påvirkning av strømmen av kjølemediet i den utvendige ringformete strømningskanalen (9), og for å bli omdirigert mot den innvendige flaten av termoplastrøret (1), oppfinnelsen er karakterisert ved at det kjølemediet er luft, og at det er kjøleutstyr (6) montert i returkanalen (10), hvormed i det minste temperatur og strømningshastighet for kjølevannet ført til kjøleutstyret (6), og muligens også av kjøleluften som mate inn i termoplastrør (1), justeres og reguleres basert på dimensjon og ekstrusjonshastighet av termoplastrøret (1) som tilvirkes.
