L'acier duplex de JISCO\u00a0<\/strong>P\u00e9trole <\/strong>Fait une autre grande r\u00e9ussite\u00a0: entre dans le domaine du haut de gamme<\/strong><\/h2>\n

Il y a quelques jours, parall\u00e8lement \u00e0 l'op\u00e9ration r\u00e9ussie de fond de trou d'alliage r\u00e9sistant \u00e0 la corrosion enroul\u00e9 2205 tuyaux en acier inoxydable<\/a> dans le champ p\u00e9trolif\u00e8re de Changqing de la China National Petroleum Corporation, il a marqu\u00e9 l'entr\u00e9e de l'acier duplex JISCO 2205 du p\u00e9trole dans le domaine haut de gamme.<\/p>\n

\"Duplex

La corrosion est un probl\u00e8me mondial auquel l'industrie p\u00e9troli\u00e8re est confront\u00e9e. Dans l'exploitation du p\u00e9trole et du gaz, la corrosion du sulfure d'hydrog\u00e8ne, du dioxyde de carbone, des ions chlorure et d'autres milieux est l'une des raisons importantes de la d\u00e9faillance des tuyaux. Environ un tiers des gisements de p\u00e9trole et de gaz dans le monde contiennent du sulfure d'hydrog\u00e8ne. Les gisements de mon pays, Sichuan, Changqing, Chine du Nord, Xinjiang et Jianghan, sont tous des gisements de p\u00e9trole et de gaz contenant du soufre. Le tube spiral\u00e9 en acier inoxydable alli\u00e9 2205 r\u00e9sistant \u00e0 la corrosion a une r\u00e9sistance \u00e0 la pression interne et externe de plus de 30% sup\u00e9rieure \u00e0 celle de l'acier au carbone ordinaire, ce qui est particuli\u00e8rement adapt\u00e9 aux environnements de travail \u00e0 forte corrosion. Avec l'aide de JISCO, le tube spiral\u00e9 fortement alli\u00e9 a fourni de nouvelles options pour augmenter et stabiliser la production des anciens puits contenant des milieux corrosifs tels que le sulfure d'hydrog\u00e8ne et le dioxyde de carbone dans le champ de gaz Xiagu du champ p\u00e9trolif\u00e8re de Changqing.<\/p>\n

\"Les tubes enroul\u00e9s ont des exigences \u00e9lev\u00e9es en mati\u00e8re de r\u00e9sistance \u00e0 la corrosion de l'acier inoxydable, et un contr\u00f4le par ultrasons est n\u00e9cessaire pour chaque m\u00e8tre, ce qui exige une tr\u00e8s grande puret\u00e9 de l'acier.\" Chen Xingrun, ing\u00e9nieur responsable de la branche acier inoxydable de JISCO Hongxing Co., Ltd. a pr\u00e9sent\u00e9 : \"L'aust\u00e9nite des tubes enroul\u00e9s Il y a des inclusions fragiles autour de l'interface de phase avec la ferrite, ce qui provoquera un rel\u00e2chement et des fissures pendant le processus de pliage des tubes, ce qui entra\u00eene une d\u00e9tection incoh\u00e9rente des d\u00e9fauts.\"<\/p>\n

Face \u00e0 des exigences particuli\u00e8res, chinois fournisseur de raccords de tuyauterie en acier inoxydable<\/a> JISCO a d\u00e9velopp\u00e9 une technologie sp\u00e9ciale de contr\u00f4le de l'inclusion pour l'acier inoxydable duplex 2205, qui a r\u00e9solu efficacement ce probl\u00e8me. \"La composition de notre acier inoxydable duplex 2205 est contr\u00f4l\u00e9e avec pr\u00e9cision, et l'\u00e9quivalent de r\u00e9sistance \u00e0 la piq\u00fbre est stable au-dessus de 35. Les produits ont \u00e9t\u00e9 inspect\u00e9s par les clients et tous sont qualifi\u00e9s.\" Chen Xingrun a d\u00e9clar\u00e9 : \"Cette ann\u00e9e, nous fournirons plus de 100 tonnes de plaques en acier inoxydable duplex 2205 n\u00b0 1, qui ont \u00e9t\u00e9 utilis\u00e9es pour fabriquer des tubes enroul\u00e9s pour le p\u00e9trole.\"<\/p>\n
