Abstract

La presente invención se refiere a manguito plegado para junta de tubos, caracterizado en que comprende: un tubo que tiene una sección transversal circular; un manguito de sección transversal circular telescopado sobre el tubo; una pestaña que contiene un anillo de sello en un extremo del manguito; y un anillo de sello contenido dentro de la pestaña que contiene el anillo de sello; la pestaña que contiene el anillo de sello habiendo sido compresivamente reducida en acoplamiento con la circunferencia exterior del tubo, y el manguito y el tubo habiendo sido plegados en un lugar espaciado del extremo mencionado para inmovilizar el manguito contra movimiento axial y circunferencial en relación con el tubo; cuando menos dos pliegues que se extienden hacia adentro de la periferia exterior del manguito y tubo respectivo y cada no se extiende en arco de la circunferencia del manguito y tubo respectivos sobre un radio constante de manguito y tubo respectivos, tomado desde el eje longitudinal de manguito y tubo, estos pliegues respectivos, están separados uno del otro circunferencialmente del manguito y tubo mediante puntales provistos por porciones que se extienden axialmente del manguito y tubo del radio original del manguito y tubo respectivos, estos pliegues son cada uno cóncavos hacia adentro de la superficie exterior del manguito y tubo respectivos; y los pliegues respectivos incluyen cada uno porciones que divergen radialmente hacia afuera en los extremos opuestos respectivos de los pliegues que se extienden circunferencialmente.The present invention relates to a folded tube joint sleeve, characterized in that it comprises: a tube having a circular cross section; a sleeve of circular cross-section telescoped on the tube; a flange containing a seal ring at one end of the sleeve; and a seal ring contained within the tab containing the seal ring; the flange containing the seal ring having been compressively reduced in engagement with the outer circumference of the tube, and the sleeve and tube having been folded at a location spaced from the aforementioned end to immobilize the sleeve against axial and circumferential movement relative to the tube; at least two folds extending inward from the outer periphery of the respective sleeve and tube and each not arcing the circumference of the respective sleeve and tube over a constant radius of the respective sleeve and tube, taken from the longitudinal axis of the sleeve and tube, these respective folds, are circumferentially separated from each other of the sleeve and tube by struts provided by axially extending portions of the sleeve and tube of the original radius of the respective sleeve and tube, these folds are each concave inward from the surface exterior of the respective sleeve and tube; and the respective folds each include radially outwardly diverging portions at the respective opposite ends of the circumferentially extending folds.
