Mobile arrangement for manufacturing a continuous pipeline

摘要

The invention relates to equipment for welding of pipelines, preferably within the oil and gas industries. A mobile arrangement for manufacturing a continuous pipeline comprises a resistance stub-welding apparatus 1 carried by the walls of the pipeline, an outer deburring device 7, and at least one pipe-laying device 2. A jib 3 of the pipe-laying device 2 is arranged to carry a supporting means 15 with carrying rollers 16 for carrying the pipeline 4. At the beam 3 of the pipe-laying device 2, a longitudinal support structure 6 is suspended according to the invention, the supporting means 15 being fastened thereto. The outer deburring device 7 is fastened to the front end of the longitudinal support structure 6, while the rear end of said longitudinal support structure 6 carries an induction-heating device 8 for thermal treatment of the weld.
