  • Telemetry system for the bi-directional communication of data between a well point and a terminal unit situated on the surface
    Patent number: 7416028
    Abstract: A telemetry system for bi-directional communication of data between a well point and a terminal unit situated on a surface, which can be used inside drilling or production strings. The system includes data transmission and optional reception devices. An active vehicle, which can be equipped with plural automation levels, ranging from purely tele-operated to completely autonomous, is provided for unwinding and pulling a connection line, capable of moving inside a drilling or production string, or a passive vehicle, moved by a deploying cable and a suitable winding/unwinding device, in particular a winch. A connection line, containing electric conductors and/or one or more optical fibers of the transmission and optional reception devices is provided between a well point and its corresponding point situated inside the vehicle or on the surface.

  • Automatic orbital welding machine, and a welding process for pipes of a bundle of a heat exchanger
    Publication number: 20040094514
    Abstract: The present invention relates to an electric arc automatic orbital welding machine (3) for carrying out butting welding between pipes of a bundle (2) and a cylindrical body (1) in heat exchangers, in which a cam mechanism (5) receives a circular motion around an axis (9) therefrom and generates an axial reciprocating motion along the same axis (9) and orthogonal to the plane of rotation so that the torch (7) describes the same spatial path which coincides with the intersection line between the pipe segment (2) and the cylindrical body (1).
