Le degr\u00e9 de d\u00e9formation n'est pas le m\u00eame, comme le chanfreinage du joint ou du manchon, la rugosit\u00e9, la forme, le contr\u00f4le de la tol\u00e9rance n'est pas raisonnable, ce qui conduit \u00e9galement \u00e0 l'\u00e9chec du flambage.<\/p>\n\n\n\n<p>Traitement : Les infiltrations d'huile au niveau du flambage doivent \u00eatre remplac\u00e9es par des tuyaux en caoutchouc. Et prendre les mesures suivantes : am\u00e9liorer le processus de production, contr\u00f4ler les tol\u00e9rances dimensionnelles du tuyau, de l'\u00e2me et du manchon ; choix raisonnable du mat\u00e9riau de l'\u00e2me et du manchon, duret\u00e9 appropri\u00e9e, pour s'assurer que la d\u00e9formation apr\u00e8s le flambage ne d\u00e9passe pas la diff\u00e9rence ; en fonction des diff\u00e9rents lots de tuyaux, l'ampleur du flambage doit \u00eatre ajust\u00e9e de mani\u00e8re appropri\u00e9e, ou le manchon de la bo\u00eete de jonction doit \u00eatre redessin\u00e9 pour s'assurer que l'ampleur du flambage est appropri\u00e9e. La quantit\u00e9 de flambage doit \u00eatre ajust\u00e9e en fonction des diff\u00e9rents lots de tuyaux, ou le manchon de la bo\u00eete \u00e0 bornes doit \u00eatre redessin\u00e9 pour garantir une quantit\u00e9 de flambage appropri\u00e9e.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Ce qui pr\u00e9c\u00e8de n'est qu'une analyse de certains modes de d\u00e9faillance courants des tuyaux, et propose les m\u00e9thodes de traitement correspondantes.
