SEALING METHOD FOR COILED PIPE

A method of manufacturing pipe coils (1) comprising extruding molten polymer (3) compound through a tool (5, 7, 9); cooling and cutting the polymer (3) to form a pipe (1); sterilising the inside of the pipe (1) and sealing each end (19) of the sterile pipe (1) with at least one sealing means (29, 33...

Beschreibung
Zusammenfassung:	A method of manufacturing pipe coils (1) comprising extruding molten polymer (3) compound through a tool (5, 7, 9); cooling and cutting the polymer (3) to form a pipe (1); sterilising the inside of the pipe (1) and sealing each end (19) of the sterile pipe (1) with at least one sealing means (29, 33, 35), wherein the at least one sealing means (29, 33, 35), maintains the sterility of the pipe (1). La présente invention concerne un procédé de fabrication de serpentins en tube (1) qui consiste à extruder un composé de polymère fondu (3) à l'aide d'un outil (5, 7, 9) ; à refroidir et couper le polymère (3) afin d'obtenir un tuyau (1) ; à stériliser l'intérieur du tuyau (1) et fermer de manière étanche chaque extrémité (19) du tuyau stérile (1) à l'aide d'au moins un dispositif d'étanchéité (29, 33, 35), ledit dispositif (29, 33, 35) permettant de conserver la stérilité du tuyau (1).
