DEVICE FOR SUPPORTING A PIPING SYSTEM WHOSE THICKNESS IS LOW IN RELATION TO THE DIAMETER

摘要

The invention relates to a device for supporting a pipe whose thickness is low relative to the diameter. The support device comprises a rigid collar 3 surrounding the pipe 1 in such a way as to AN ANNULAR SPACE AROUND THEREOF AND A DEFORMABLE ANNULAR ELEMENT 6 RADIALLY DISPOSED BETWEEN THE PIPE 1 AND THE COLLAR 3. THE DEFORMABLE ELEMENT 6 IS CONSISTING OF AT LEAST TWO ANNULAR SECTIONS 6A, 6B, 6C ARRANGED ONE FOLLOWING FROM THE OTHER AROUND THE PIPING 1. EACH OF THE SECTORS 6 CONTAINS TWO ENVELOPED SHEETS 7, 8 AND AN ELASTIC SHEET 10 IN THE FORM OF CYLINDER PORTIONS. THE ELASTIC SHEET 10 IS IN SUPPORT ON THE ENVELOPED SHEETS 7, 8 THROUGH AXIAL RODS 11, 12, REGULARLY SPACED AND PLACED IN QUINCONCE ON EITHER ELASTIC 10. / P / P The invention applies, in particular, to the support of secondary pipes of a fast neutron NUCLEAR REACTOR COOLED BY LIQUID SODIUM. / P
