Abrégé
(EN)
A seismic coupling is provided for coupling a first longitudinal section of plain end plastic pipe (27) to a second longitudinal section of plastic pipe (67). The coupling is provided in two halves with a left half (21) being initially installed on the plain end of the first section of pipe. An internal shoulder (39) is fused onto the first section of pipe and a right half of the coupling (45) is then fused onto the left half to capture the first end of pipe within the coupling. The second pipe end is then installed within an end opening of the coupling and held in position by a connector (75) installed between the right half of the coupling and the second pipe end Internal seals are provided for sealing the first and second pipe ends within the interior of the coupling.

La présente invention concerne un couplage sismique permettant le couplage d'un premier tronçon longitudinal d'une conduite en matière plastique à extrémité lisse à un second tronçon de conduite en matière plastique. Le couplage est assuré en deux moitiés avec une moitié de gauche initialement installée sur l'extrémité lisse du premier tronçon de conduite. Un épaulement interne est fusionné sur le premier tronçon de conduite et une moitié de droite est ensuite fusionnée sur la moitié de gauche pour capturer la première extrémité de conduite au sein du couplage. La seconde extrémité de conduite est ensuite installée dans une ouverture d'extrémité du couplage et maintenue par un raccord installé entre la moitié de droite du couplage et la seconde extrémité de conduite. Des joints internes sont agencés pour étanchéifier les première et seconde extrémités à l'intérieur du couplage.
