    • The invention relates to a device for centering and clamping conduits which are preferably made from alloy steel and which are positioned end to end in order to be welded to form a pipeline. The invention comprises: means for centering and clamping two conduits that are to be welded, optional leak-tight partition means which define an inerting chamber at the mating surface, and inert gas distribution means for creating a protective atmosphere at the mating surface. The inventive device also comprises at least means for regulating the flow of inert gas and/or the supply pressure of said inert gas as a function of the concentration of O2 measured in the protective atmosphere and/or the pressure measured within said atmosphere, such as to maintain the O2 content of the atmosphere below a pre-determined alarm threshold value and/or the pressure of the atmosphere below a pre-determined threshold value.

    • Clamp for mechanical parts such as tubes or pipes, comprising a flange (5) with parts (13A, 13B, 13C) connected to one another so as to be pivotable as far as a closed position in which they are continuous. A locking device may be actuated when the flange is closed. The clamp further comprises supports (55; 57) by which rails (49) are connected to the parts with limited freedom of relative movement. The adjacent end faces of the rails have mating surfaces forming a connection by positive locking, which is active in the vicinity of the closed position. Each connection guides the end faces relative to one another into a working position in which the rails (49) form a guide path for tools, and helps to maintain this position when the clamping device is actuated.
    • 用于诸如管或管的机械部件的夹具,包括具有彼此连接的部分(13A,13B,13C)的凸缘(5),以便能够枢转到其连续的关闭位置。 当法兰关闭时,可以致动锁定装置。 夹具还包括支撑件(55; 57),通过该支撑件,轨道(49)以相对移动的有限自由度连接到部件。 轨道的相邻端面具有通过正锁定形成连接的配合表面,其在关闭位置附近是活动的。 每个连接件将端面相对于彼此引导到工作位置,在工作位置,轨道(49)形成工具的引导路径,并且有助于在夹紧装置致动时保持该位置。

    • Device for working tubes, comprising a flange (5) recessed on the inside, with plates (13A, 13B, 13C) joined together so as to be pivotable, up to a closed position in which these plates are joined to form a crown, and a locking device for the flange. The adjacent ends of two plates have mating surfaces forming a connection by positive locking, this connection being active in the vicinity of the closed position of the flange (5). Each positively locking connection comprises two complementary surfaces (37) coming into mutual contact in the closed position of the flange. The locking device comprises at least one latch that can be actuated in this position, which acts on the adjacent ends of the plates to clamp their complementary contact surfaces against one another.
    • 用于工作管的装置,包括在内侧凹入的凸缘(5)与连接在一起以便可枢转的板(13A,13B,13C),直到这些板被接合以形成冠部的关闭位置,以及 用于法兰的锁定装置。 两个板的相邻端部具有通过正向锁定形成连接的配合表面,该连接在凸缘(5)的关闭位置附近是有效的。 每个正向锁定连接包括在凸缘的关闭位置中相互接触的两个互补表面(37)。 锁定装置包括至少一个可以在该位置致动的闩锁,其作用在板的相邻端部上,以将彼此互补的接触表面夹紧。

    • To abut hollow profiled parts, at least two frames includes actuators distributed in an equivalent manner to one another. Each actuator includes a portion which can be displaced in a plane common to the other actuators of the frame so as to project from the frame; the frames are each positioned in an end region of a respective part. The equivalent actuators are mutually opposed; the mobile portions of the actuators of one frame and of the actuators of the other frame are displaced into respective working positions, in which they exert forces on the wall of their respective part so that the end regions of these parts match one another; the parts are fixed to one another in their respective end regions.
