Abstract

Una conexión de conducto expandible plástica y radialmente que incluye una primera superficie de sellado dispuesta próxima a un extremo de un miembro de pasador de la conexión y una segunda superficie de sellado dispuesta próxima a un extremo de un miembro de caja de la conexión. La primera y segunda superficies de sellado están sustancialmente opuestas entre sí durante la conexión del miembro de caja y el miembro de pasador. La conexión también incluye una primera superficie de holgura próxima a la primera superficie de sellado en el miembro pasador y una segunda superficie de holgura próxima a la segunda superficie de sellado en el miembro de caja. La primera y segunda superficies de sellado incluyen un dispositivo de antirotación. La primera y segunda superficie de holgura y la primera y segunda superficies de sellado cada una tiene un diámetro de tal manera que antes de la expansión radial plástica del miembro de caja y el miembro de pasador, las superficies de holgura están próximas entre sí y no hacen contacto la una con la otra, y no el dispositivo de anti-rotación. Después de la expansión plástica radial, la primera y segunda superficies de sellado desarrollan una presión de contacto, las superficies de holgura permanecen sin hacer contacto, y se engancha el dispositivo de anti-rotación.A plastic and radially expandable conduit connection that includes a first sealing surface disposed close to one end of a connection pin member and a second sealing surface disposed close to one end of a connection box member. The first and second sealing surfaces are substantially opposite each other during the connection of the box member and the pin member. The connection also includes a first clearance surface close to the first sealing surface in the pin member and a second clearance surface close to the second sealing surface in the box member. The first and second sealing surfaces include an anti-rotation device. The first and second clearance surface and the first and second sealing surfaces each have a diameter such that before the plastic radial expansion of the box member and the pin member, the clearance surfaces are close to each other and not they make contact with each other, and not the anti-rotation device. After radial plastic expansion, the first and second sealing surfaces develop a contact pressure, the slack surfaces remain without contact, and the anti-rotation device is engaged.
