A device for assembly of a flexible conduit element consisting essentially of a flexible ring-corrugated or helical-shaped bellows body which is displaced over an inner arbor in order to introduce a jacket into the corrugations of the bellows body, has an the inner arbor comprising actuating elements for engagement into the corrugations of the bellows body at an inner side thereof. The inner arbor has an axial length which can be adjusted.

Device for assembling a flexible conduit element

A sealing device for the sealed connection of two pipes placed end to end includes an upper component and a lower component. The upper component includes a frustoconical rib extending outward from a cylindrical end part and diverging upward into a first wall forming a return, an elastically deformable external skirt formed from a second wall connected to the frustoconical rib through the return, a circular groove defined between the rib and the skirt and formed by the first and second walls, and a retainer provided in a lower edge of the external skirt. The lower component is matable with the upper component and includes a third wall forming a frustoconical socket that flares upward, a fourth wall forming a frustoconical external skirt diverging downward, and a circular rib formed by merger of the third and fourth walls. The circular rib is sized to enter and come into elastic contact with an internal face of the groove and the retainer snap-fastens under the external skirt of the lower component to fasten the lower component to the upper component.

Device for the sealed butt connection of two metal pipes

A reinforced flexible pipe includes an impermeable hose and a reinforcement tube composed of an interlacement of flat rovings wound helically about the axis of the hose. Each flat roving is constructed of a plurality of filaments, such as wires. The interlacement of the coaxial reinforcement tube includes metal tapes helically wound about the axis of the hose and interlaced with the flat rovings.
