ABSTRACT:
A hot pipeline is welded to a flange which is supported by brackets connected to a nozzle. The pipeline with a flange can expand freely radially. Welded to the other end of the flange is a pipe, which can withstand an axial temperature gradient between a temperature T.sub.1 at the pipeline and flange, and a temperature t.sub.2 at a compensator and the nozzle. The axial expansion of pipe is accommodated by the compensator, which is welded to the pipe and at its other end to the nozzle. The pipeline, the flange, the pipe and the compensator are subject to the difference between pressure p.sub.2 in the vessel and the pressure p.sub.1 in the pipeline.
