Title
(EN) METHOD FOR CONNECTING TWO REINFORCED THERMOPLASTIC TUBES
(FR) PROCEDE DE RACCORDEMENT DE DEUX TUBES EN MATERIAU THERMOPLASTIQUE RENFORCE
Abstract
(EN)
The invention concerns a method for connecting two tubes (18A, 18B) of same diameter made of reinforced thermoplastic material. The ends (24, 26) of the two tubes (18A, 18B) are firstly butt-welded along a circumferential weld seam (28). After welding (28), an outer casing (30) made of reinforced thermoplastic material is mounted over substantially the whole length of the circumferential weld seam (28) overlapping on either side of the weld seam (28) on the end sections of the two tubes (18A, 18B). The outer casing (30) is heated and radially pressed until the outer casing (30) and the end sections of the tubes (18A, 18B) become interpenetrated.
(FR)
L'invention concerne un procédé de raccordement de deux tubes (18A, 18B) de même diamètre en matériau thermoplastique renforcé. Les extrémités (24, 26) des deux tubes (18A, 18B) sont d'abord soudées bout à bout suivant une soudure périphérique (28). Après réalisation de la soudure (28), une enveloppe externe (30) en matériau thermoplastique renforcé est rapportés sur l'essentiel de la longueur de la soudure périphérique (28) en débordant de part et d'autre de la soudure (28) sur les tronçons d'extrémité des deux tubes (18A, 18B). L'enveloppe externe (30) est chauffée et pressée radialement jusqu'à interpénétration de l'enveloppe externe (30) et des tronçons d'extrémité des deux tubes (18A, 18B).
