Device for Centering and Clamping Tubular Parts, Comprising Means for the Real-Time Mesurement and Regulation of the Moisture Content

摘要

The invention relates to a device for centring 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 centring and clamping two conduits that are to be welded, optional leak-tight patition 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 the real-time measurement of the moisture content of the protective atmosphere and means ( 3 ) for the real-time regulation of the moisture content as a function of said measurements, such that the moisture content of the atmosphere is maintained below a pre-determined threshold value.
