Abstract: Equalizing valve (1) comprising a duct (6) having an inlet section (7) and an outlet section (8), a seat (10) and a valve element (12) able to move between a closed position and an open position, characterized in that said duct is able to admit a flow in which, for any flow line (13) between said inlet section and said outlet section, the velocity vector (15) at a given point makes an angle with the velocity vector (14) in the inlet section which increases with the distance away from the inlet section, the angle between the velocity vector (16) in the outlet section and the velocity vector in the inlet section ranging between 80° and 150°, and in which the valve element, in the closed position, makes an angle of between 0° and 70° with the normal to the outlet section.

Abstract: The present disclosure describes a device for connection, by means of an injected assembly fluid, of a first and a second pipe elements for transport of liquid or gaseous fluid, the second element having a socket receiving an end of the first element, comprising a diffusion part for diffusion of the injected assembly fluid, the diffusion part being adapted to be arranged on a circumference of the first element and against an edge of the socket, said diffusion part having at least one opening for the injection of assembly fluid into said diffusion part. The diffusion part forms a chamber for collecting said assembly fluid and for distributing it circumferentially. The device comprises directing means allowing to actively direct the assembly fluid towards a connection space between the socket and the first element.

Abstract: In known manner, a pipe system comprises a group of tubes and couplings connecting a suction station to one or more suction openings, the tubes and couplings being equipped with low voltage electric conductors for transmitting an electric stop or start signal from the station. According to the invention, the conductors equipping the tubes are in the form of strips integral with the tubes. Such strips can also equip the couplings.
