Title
(EN) APPARATUS AND METHOD FOR JOINING MOLECULARLY ORIENTED PIPE
(FR) APPAREIL ET PROCÉDÉ D'ASSEMBLAGE DE TUYAU À ORIENTATION MOLÉCULAIRE
Abstract
(EN)
A pipe pining system and pipe joint are shown in which two sections of molecularly oriented pipe are joined using heat shrinking techniques. A first section of pipe is provided having a straight, pre-formed socket with art internal diameter and with an end opening having enough clearance to allow a mating spigot section having a given external diameter to be inserted into the socket end opening. After the spigot end is inserted to a given depth, the socket is heated sufficiency so that the internal diameter of the socket end comes into contact with the external, diameter of the spigot end, the molecularly oriented pipe being in a rubbery state and exhibiting a low elastic modulus which allows the socket end to conform tightly to the spigot end external diameter without deforming the spigot end.
(FR)
L'invention concerne un système d'établissement de joint de tuyaux et un joint de tuyaux, dans lesquels deux sections de tuyau à orientation moléculaire sont raccordées. Une première section de tuyau est pourvue d'un embout femelle droit préformé ayant un diamètre intérieur connu et d'une ouverture d'extrémité ayant suffisamment de jeu pour permettre à une section mâle correspondante ayant un diamètre extérieur donné d'être insérée dans l'ouverture de l'extrémité femelle. Une fois que l'extrémité mâle est insérée à une profondeur donnée, l'embout femelle est chauffé de manière suffisante pour que le diamètre intérieur de l'extrémité femelle vienne en contact avec le diamètre extérieur de l'extrémité mâle, le tuyau à orientation moléculaire étant dans un état caoutchouteux et présentant un faible module d'élasticité qui permet à l'extrémité femelle d'épouser étroitement le diamètre extérieur de l'extrémité mâle sans déformer l'extrémité mâle.
