Title (EN) FLEXIBLE PIPE CONNECTOR AND METHOD OF USING THE SAME
(FR) RACCORD DE TUYAU SOUPLE ET SON PROCÉDÉ D'UTILISATION
Abstract:
(EN) A flexible pipe connector (200) for joining a pressurised mains pipe to a service pipe, the connector comprising: • a corrugated longitudinal body portion (202) having a first end (208), a second end (210) and an internal bore therebetween, said longitudinal body portion further comprising a plurality of corrugations spaced along the length thereof, the corrugations defining a maximum internal diameter of the bore at a peak 204 of a corrugation and a minimum internal diameter of the bore at a trough (206) of a corrugation; • a first spigot socket (212) at said first end of the longitudinal body portion; and • a second spigot socket (214) at said second end of the longitudinal body portion; • wherein for a defined volumetric flow rate, the head loss of a fluid flowing through said body portion is no greater than if the fluid were flowing in a smooth bored pipe of the same length and having the same internal diameter as the first and second spigot sockets; and • wherein the minimum internal diameter of said corrugated internal bore is greater than the maximum internal diameter of said first and second spigots.
(FR) L'invention concerne un raccord de tuyau souple (200) pour relier un tuyau principal mis sous pression à un tuyau de service, le raccord comprenant : • une partie de corps longitudinale ondulée (202) ayant une première extrémité (208), une seconde extrémité (210) et un alésage interne entre celles-ci, ladite partie de corps longitudinale comprenant en outre une pluralité d'ondulations espacées le long de la longueur de celle-ci, les ondulations définissant un diamètre interne maximal de l'alésage au niveau d'une crête (204) d'une ondulation et un diamètre interne minimal de l'alésage au niveau d'une dépression (206) d'une ondulation ; • une première douille à bout uni (212) au niveau de ladite première extrémité de la partie de corps longitudinale ; et • une seconde douille à bout uni (214) au niveau de ladite seconde extrémité de la partie de corps longitudinale ; • pour un débit volumétrique défini, la perte de charge d'un fluide s'écoulant à travers ladite partie de corps n'étant pas plus grande que si le fluide s'écoulait dans un tuyau à alésage lisse de même longueur et ayant le même diamètre interne que les première et seconde douilles à bout uni ; et • le diamètre interne minimal dudit alésage interne ondulé étant supérieur au diamètre interne maximal desdits premier et second bouts unis.
