Abstract

TUYAU METALLIQUE POUR FLUIDE A HAUTE PRESSION A PAROI EPAISSE SOUMIS A UN TRAITEMENT THERMIQUE DE MANIERE A PRODUIRE UNE TENSION RESIDUELLE SUR LA SURFACE EXTERNE ET UNE COMPRESSION RESIDUELLE SUR LA SURFACE INTERNE. CE RESULTAT EST OBTENU EN CHAUFFANT LA SURFACE EXTERIEURE JUSQU'A LA TEMPERATURE DE TRANSFORMATION DU METAL ET SIMULTANEMENT OU PRESQUE DE REFROIDIR LA SURFACE INTERNE PAR PASSAGE D'UN MILIEU REFROIDISSEUR. ON UTILISE DE PREFERENCE DES TUYAUX EN ACIER STS35 OU SUS304L AVEC DES DIAMETRES EXTERIEURS DE 6 A 35MM ET DES DIAMETRES INTERIEURS DE 2 A 12MM.METAL HOSE FOR THICK WALL HIGH PRESSURE FLUID SUBJECT TO HEAT TREATMENT SO AS TO PRODUCE RESIDUAL TENSION ON THE OUTER SURFACE AND RESIDUAL COMPRESSION ON THE INTERNAL SURFACE. THIS RESULT IS OBTAINED BY HEATING THE EXTERIOR SURFACE TO THE METAL TRANSFORMATION TEMPERATURE AND SIMULTANEOUSLY OR NEARLY COOLING THE INTERNAL SURFACE BY PASSING THROUGH A COOLING MEDIUM. STS35 OR SUS304L STEEL PIPES WITH OUTSIDE DIAMETERS OF 6 TO 35MM AND INTERNAL DIAMETERS OF 2 TO 12MM ARE PREFERREDLY USED.
