\u00c0 propos des applications du tuyau duplex 2205<\/h2>\n

Tuyau duplex<\/a> est largement utilis\u00e9 dans divers domaines en raison de ses avantages uniques. Il se r\u00e9sume comme suit :<\/p>\n

\"Duplex<\/a><\/p>\n

Industrie des p\u00e2tes et papiers<\/strong>: L'industrie des p\u00e2tes et papiers est la premi\u00e8re industrie de transformation \u00e0 duplexer l'acier. L'utilisation d'acier biphas\u00e9 \u00e0 la place des marmites en acier inoxydable 304 et 316 aust\u00e9nitique \u00e0 l'acide sulfurique et \u00e0 l'acide sulfurique am\u00e9liore la r\u00e9sistance \u00e0 la corrosion et la r\u00e9sistance du cuiseur vapeur, tout en r\u00e9duisant l'\u00e9paisseur de la paroi et le poids total du cuiseur vapeur. C'est \u00e9galement un march\u00e9 important pour l'inventeur de l'acier duplex 2205, Outokumpu, Su\u00e8de.<\/p>\n

Industrie de transformation chimique<\/strong>: L'industrie de transformation chimique a un large \u00e9ventail d'applications et des conditions de travail compliqu\u00e9es. Les r\u00e9servoirs de stockage pour la conservation de l'acide phosphorique industriel par voie humide sont g\u00e9n\u00e9ralement en acier inoxydable aust\u00e9nitique de type 316L ou 317L, mais les parois sont \u00e9paisses. Avec l'acier duplex 2205, la r\u00e9sistance est presque le double de celle du 316L et du 317L, et l'\u00e9paisseur de la paroi peut \u00eatre r\u00e9duite, r\u00e9duisant ainsi l'importance et le co\u00fbt du r\u00e9servoir. Parall\u00e8lement, dans l'environnement industriel de l'acide sulfurique, notamment en pr\u00e9sence d'ions chlorure, le 2205 pr\u00e9sente une meilleure r\u00e9sistance \u00e0 la corrosion locale que l'acier inoxydable aust\u00e9nitique ordinaire.<\/p>\n

Industrie du raffinage<\/strong>: L'industrie du raffinage est l'un des domaines qui utilise le plus d'aciers duplex. Il est principalement utilis\u00e9 dans la distillation atmosph\u00e9rique et sous vide, l'hydrod\u00e9sulfuration par craquage catalytique et d'autres dispositifs, et est utilis\u00e9 au pays et \u00e0 l'\u00e9tranger. En outre, les aciers duplex sont de plus en plus utilis\u00e9s dans la production de gaz acide et de p\u00e9trole, et sont principalement utilis\u00e9s comme syst\u00e8mes de canalisations pour le rev\u00eatement des canalisations, onshore et offshore, et les \u00e9changeurs de chaleur.<\/p>\n

Industrie p\u00e9trochimique<\/strong>: L'environnement corrosif des industries p\u00e9trochimiques et chimiques est caract\u00e9ris\u00e9 par une temp\u00e9rature de r\u00e9action \u00e9lev\u00e9e, et le milieu contient souvent une concentration \u00e9lev\u00e9e ou moyenne de chlorure, qui est facile \u00e0 induire. fissuration par corrosion sous contrainte<\/a> en acier inoxydable.<\/p>\n

Industrie alimentaire et des boissons<\/strong>: La production de l'industrie agroalimentaire est g\u00e9n\u00e9ralement trait\u00e9e dans des solutions chaudes contenant des ions chlorure. Les aciers duplex pr\u00e9sentent des avantages uniques dans la fissuration par corrosion sous contrainte.<\/p>\n

Transport<\/strong>: En raison de la haute r\u00e9sistance et de l'excellente r\u00e9sistance \u00e0 la corrosion de l'acier duplex, il pr\u00e9sente de grands avantages lorsqu'il est utilis\u00e9 dans la production de citernes chimiques. Il r\u00e9duit le poids du navire et r\u00e9duit la consommation de carburant. A cet \u00e9gard, le plus utilis\u00e9 est l'acier duplex 2205. Dans le m\u00eame temps, il peut r\u00e9pondre \u00e0 la r\u00e9sistance \u00e0 la corrosion des mat\u00e9riaux requis pour la cargaison.<\/p>\n

Industrie de la construction de murs<\/strong>: Dans les zones c\u00f4ti\u00e8res, l'air est rempli de l'atmosph\u00e8re marine \u00e9vapor\u00e9e de la mer, o\u00f9 la concentration en ions chlorure est beaucoup plus \u00e9lev\u00e9e que l'air int\u00e9rieur, de sorte que le mat\u00e9riau r\u00e9sistant \u00e0 l'eau de mer est n\u00e9cessaire. La r\u00e9sistance \u00e0 la corrosion des aciers duplex pr\u00e9sente cet avantage, et sa haute r\u00e9sistance r\u00e9duit \u00e9galement le poids. \u00c0 l'heure actuelle, de nombreuses plates-formes p\u00e9troli\u00e8res offshore utilisent de l'acier duplex pour fabriquer des murs antid\u00e9flagrants.<\/p>\n

De plus, l'acier duplex a \u00e9galement \u00e9t\u00e9 utilis\u00e9 avec succ\u00e8s dans les \u00e9changeurs de chaleur de traitement de l'eau, les conduites d'eau chaude et les chauffe-eau.<\/p>","protected":false},"featured_media":5213,"template":"","categories":[186],"tags":[],"class_list":["post-5244","blog","type-blog","status-publish","has-post-thumbnail","hentry","category-stainless-steel-knowledge"],"yoast_head":"\nAbout The Applications Of Duplex 2205 Pipe - Stainless Steel Pipe and Fittings | KAYSUNS<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.kaysuns.com\/fr\/blog\/sur-lapplication-du-tube-duplex-2205\/\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"About The Applications Of Duplex 2205 Pipe - Stainless Steel Pipe and Fittings | KAYSUNS\" \/>\n<meta property=\"og:description\" content=\"About The Applications Of Duplex 2205 Pipe Duplex pipe is widely used in various fields due to its unique advantages.
