\"Fabrication<\/h2>\n

Introduction<\/span><\/h2>\n

Les tubes en acier sont une n\u00e9cessit\u00e9 dans presque toutes les industries. Ils font partie int\u00e9grante de l'acc\u00e9l\u00e9ration du travail industriel et de l'efficacit\u00e9 des processus.<\/span><\/p>\n

Parmi les nombreux tubes en acier, les tubes sans soudure sont l'un des plus recherch\u00e9s. Gr\u00e2ce \u00e0 leurs propri\u00e9t\u00e9s m\u00e9caniques, ils offrent une meilleure durabilit\u00e9 que les tuyaux soud\u00e9s. Comme ils proviennent d'une billette de m\u00e9tal solide, ils sont plus r\u00e9sistants aux contraintes et \u00e0 la rupture. Ils sont souvent utilis\u00e9s dans des applications de haute pr\u00e9cision et de haute pression.<\/span><\/p>\n

Poursuivez la lecture de ce blog pour en savoir plus sur les tuyaux sans soudure et leur fabrication.<\/p>\n

<\/h2>\n

Qu'est-ce qu'un tuyau sans soudure ?<\/span><\/h2>\n

Les tuyaux sans soudure sont une variante de tuyaux en acier fabriqu\u00e9s sans joints soud\u00e9s, d'o\u00f9 leur nom. L'absence de joints r\u00e9duit les risques de rupture sous l'effet d'une pression et d'un stress intenses. Contrairement aux tuyaux soud\u00e9s, ils offrent des surfaces plus lisses et des diam\u00e8tres uniformes.<\/span><\/p>\n

Ces propri\u00e9t\u00e9s leur conf\u00e8rent une durabilit\u00e9 et une r\u00e9sistance \u00e0 la corrosion sup\u00e9rieures. Toutes ces caract\u00e9ristiques remarquables les rendent id\u00e9ales pour l'industrie p\u00e9troli\u00e8re et gazi\u00e8re et la construction.<\/span><\/p>\n

<\/h2>\n

Historique du d\u00e9veloppement des tubes sans soudure<\/h2>\n

L'histoire des tuyaux sans soudure remonte \u00e0 la fin du 19e si\u00e8cle. Avec les progr\u00e8s de l'industrialisation, divers proc\u00e9d\u00e9s de fabrication se sont progressivement d\u00e9velopp\u00e9s. En 1885, les fr\u00e8res Mannesmann ont invent\u00e9 une machine. Elle perce des trous \u00e0 travers des rouleaux. Cela permettait de transformer l'acier en tuyaux sans soudure. Cette invention a permis d'am\u00e9liorer les proc\u00e9d\u00e9s de laminage en 1891. Elle marque une nouvelle \u00e9tape dans la fabrication des tubes sans soudure.<\/p>\n

En 1903, le Suisse Ritteriefel invente la machine automatique \u00e0 laminer les tubes, qui am\u00e9liore encore l'efficacit\u00e9 de la production. L'av\u00e8nement des \u00e9quipements d'extension a donn\u00e9 naissance \u00e0 l'industrie moderne des tubes d'acier sans soudure. Cette \u00e9volution est due aux laminoirs continus et aux machines \u00e0 foncer les tubes.<\/p>\n

En 1930, l'introduction de laminoirs \u00e0 trois cylindres, d'extrudeuses et de laminoirs \u00e0 froid a favoris\u00e9 l'avancement de la technologie de fabrication des tubes sans soudure. Au milieu du 20e si\u00e8cle, les machines de d\u00e9tente et les flans de coul\u00e9e continue ont am\u00e9lior\u00e9 l'efficacit\u00e9. Les tuyaux sans soudure sont ainsi devenus plus comp\u00e9titifs que les tuyaux soud\u00e9s.<\/p>\n

Dans les ann\u00e9es 1970, les ventes de tubes sans soudure et de tubes soud\u00e9s \u00e9taient pratiquement identiques. Les tubes sans soudure n'ont pas de soudures et r\u00e9sistent \u00e0 des pressions \u00e9lev\u00e9es. Ils sont largement utilis\u00e9s dans les domaines \u00e0 haute r\u00e9sistance. Leur demande augmente de plus de 5% par an. Ils sont en train de devenir un produit de base sur le march\u00e9 mondial des tubes en acier.<\/p>\n

<\/h2>\n

Comment fabrique-t-on un tube d'acier sans soudure ?<\/b><\/h2>\n

La fabrication de tuyaux sans soudure commence par une solide billette d'acier. Ce morceau de m\u00e9tal est soumis \u00e0 un processus de chauffage pour atteindre une mall\u00e9abilit\u00e9 et une temp\u00e9rature id\u00e9ales. Ensuite, les ouvriers le percent et l'\u00e9tirent, le transformant en un tube creux.<\/span><\/p>\n

Ce tube est ensuite soumis \u00e0 un processus d'allongement et de laminage afin de r\u00e9duire son diam\u00e8tre. Au cours de ce processus, les ouvriers ins\u00e8rent un mandrin pour mesurer le diam\u00e8tre interne du tube. Une s\u00e9rie de traitements thermiques est mise en place pour obtenir les propri\u00e9t\u00e9s m\u00e9caniques du tube.<\/span><\/p>\n

Apr\u00e8s avoir atteint le diam\u00e8tre et la longueur souhait\u00e9s, le tube est refroidi. Les touches finales comprennent le post-traitement, tel que le polissage de la surface et le rev\u00eatement. Enfin, la machine coupe le tuyau sans soudure \u00e0 la longueur souhait\u00e9e.<\/span><\/p>\n

S\u00e9lection des mati\u00e8res premi\u00e8res<\/span><\/h3>\n

Les tubes sans soudure constituent une option durable pour diverses applications. Cependant, pour maximiser leur polyvalence, diff\u00e9rents mat\u00e9riaux doivent \u00eatre disponibles pour la transformation. La s\u00e9lection des mati\u00e8res premi\u00e8res est essentielle pour obtenir les propri\u00e9t\u00e9s id\u00e9ales du tube, notamment la r\u00e9sistance \u00e0 la traction, la limite d'\u00e9lasticit\u00e9 et la duret\u00e9.<\/span><\/p>\n

Voici les mat\u00e9riaux les plus courants pour la fabrication de tuyaux sans soudure :<\/span><\/p>\n

Acier au carbone<\/b>: Commun pour les tuyaux d'usage g\u00e9n\u00e9ral, offrant une bonne r\u00e9sistance et une bonne soudabilit\u00e9. Convient aux applications \u00e0 basse pression comme l'eau, le gaz et les syst\u00e8mes \u00e0 basse temp\u00e9rature.<\/span><\/p>\n

Acier alli\u00e9<\/b>: Compos\u00e9 d'\u00e9l\u00e9ments d'alliage tels que le chrome, le nickel et le molybd\u00e8ne. Cette composition permet d'obtenir une plus grande solidit\u00e9, une plus grande t\u00e9nacit\u00e9 et une plus grande r\u00e9sistance \u00e0 la chaleur et \u00e0 la corrosion.<\/span><\/p>\n

Acier inoxydable<\/b>: Garantit une r\u00e9sistance \u00e0 la corrosion et une robustesse exceptionnelles. Il est souvent utilis\u00e9 dans des environnements corrosifs, tels que la marine et le traitement chimique.<\/span><\/p>\n

\"Comment<\/h2>\n

Les \u00e9tapes de la fabrication en d\u00e9tail<\/span><\/h2>\n

Voici un guide plus d\u00e9taill\u00e9 sur la fabrication des tuyaux sans soudure.<\/span><\/p>\n

Chauffage<\/span><\/h2>\n

L'ensemble du processus de fabrication commence par le premier processus de chauffage. Avant de pouvoir bosseler l'\u00e9norme billette d'acier, il faut la passer dans un four \u00e0 une temp\u00e9rature d'environ 1 200\u00b0Celsius. Cette temp\u00e9rature extr\u00eame ramollit l'acier sans le faire fondre. \u00c0 la sortie du four, l'acier est incandescent et suffisamment mall\u00e9able pour les \u00e9tapes suivantes.<\/span><\/p>\n

Extrusion<\/span><\/h3>\n

Des outils rotatifs industriels percent la billette flamboyante pour cr\u00e9er une coquille creuse. Le processus d'allongement fait passer la coquille \u00e0 travers une s\u00e9rie de rouleaux robustes. La forme et la taille initiales du tube sont ainsi obtenues.<\/span><\/p>\n

Expansion du trou<\/span><\/h3>\n

Tout en dilatant le tube creux, les ouvriers continueront \u00e0 y forcer un mandrin. Cette \u00e9tape est cruciale pour obtenir un diam\u00e8tre interne lisse et une \u00e9paisseur de paroi uniforme. Le fraisage \u00e0 l'aide d'un mandrin implique un laminage et un \u00e9tirement continus pour obtenir les dimensions souhait\u00e9es.<\/span><\/p>\n

Refroidissement<\/span><\/h3>\n

Apr\u00e8s avoir obtenu la taille et les dimensions id\u00e9ales, le tube est progressivement refroidi. Ce processus de refroidissement se d\u00e9roule dans un environnement contr\u00f4l\u00e9 afin d'\u00e9viter les contraintes thermiques. Il permet \u00e9galement de conserver les propri\u00e9t\u00e9s m\u00e9caniques int\u00e9grales du tube. Le refroidissement complet du tube marque la solidification du tube dans son diam\u00e8tre final.<\/span><\/p>\n

Lissage<\/span><\/h3>\n

Les \u00e9tapes pr\u00e9c\u00e9dentes ne garantissent pas la r\u00e9ussite totale de la fabrication d'un tuyau parfait. M\u00eame apr\u00e8s le refroidissement, il y aura des d\u00e9formations et des courbures. C'est pourquoi les tuyaux doivent encore passer par une machine \u00e0 redresser. Des rouleaux ou une machine \u00e0 redresser exercent une pression contr\u00f4l\u00e9e pour aligner le tuyau. Cela permet de garantir que le produit final est g\u00e9om\u00e9triquement pr\u00e9cis et utilisable.<\/span><\/p>\n

Post-traitement<\/span><\/h3>\n

Le post-traitement peut comprendre le polissage de la surface, le filetage ou le traitement thermique pour am\u00e9liorer les propri\u00e9t\u00e9s. Les ouvriers peuvent \u00e9galement ajouter un rev\u00eatement de surface pour prot\u00e9ger le tube contre l'abrasion et la corrosion. Cette \u00e9tape permet de s'assurer que le tube r\u00e9pond aux normes d'application sp\u00e9cifiques.<\/span><\/p>\n

Contr\u00f4le de la qualit\u00e9<\/span><\/h3>\n

Le contr\u00f4le de la qualit\u00e9 v\u00e9rifie la pr\u00e9cision des dimensions, la r\u00e9sistance et les d\u00e9fauts de surface du tube. Des m\u00e9canismes d'essai s\u00fbrs, notamment des inspections aux rayons X et aux ultrasons, garantissent l'absence de d\u00e9fauts sur les tubes. Le tube est soumis \u00e0 une inspection finale avant d'\u00eatre exp\u00e9di\u00e9.<\/span><\/p>\n

Outre les tubes sans soudure lamin\u00e9s \u00e0 chaud, il existe \u00e9galement un type de tube sans soudure \u00e9tir\u00e9 \u00e0 froid. Tous deux offrent des propri\u00e9t\u00e9s distinctes n\u00e9cessaires \u00e0 des applications diff\u00e9rentes. Voici un examen plus approfondi des diff\u00e9rences de processus entre ces deux types de tuyaux.<\/span><\/p>\n

Tube sans soudure lamin\u00e9 \u00e0 chaud<\/span><\/h3>\n

Le point cl\u00e9 des tubes lamin\u00e9s \u00e0 chaud est que la billette est chauff\u00e9e \u00e0 environ ou un peu plus de mille degr\u00e9s Celsius. L'ensemble du processus consiste \u00e0 fa\u00e7onner le tube pendant qu'il est br\u00fblant.<\/span><\/p>\n

Ce processus permet de cr\u00e9er un tuyau qui est meilleur qu'un tuyau soud\u00e9 dans la plupart des cas. Cependant, le tuyau sans soudure lamin\u00e9 \u00e0 chaud reste inf\u00e9rieur au tuyau sans soudure \u00e9tir\u00e9 \u00e0 froid. Il pr\u00e9sente une finition de surface plus rugueuse en raison de l'oxydation et offre \u00e9galement une r\u00e9sistance \u00e0 la traction plus faible.<\/span><\/p>\n

Bien qu'il soit plus abordable et qu'il puisse r\u00e9sister \u00e0 l'application g\u00e9n\u00e9rale des tuyaux sans soudure.<\/span><\/p>\n

Tube sans soudure \u00e9tir\u00e9 \u00e0 froid<\/span><\/h3>\n

Les tubes sans soudure \u00e9tir\u00e9s \u00e0 froid sont le choix par excellence si vous recherchez un meilleur choix que les tubes lamin\u00e9s \u00e0 chaud. Le processus consiste \u00e0 travailler sur un tube lamin\u00e9 \u00e0 chaud \u00e0 temp\u00e9rature ambiante. \u00c0 partir de l\u00e0, le tube passe par une s\u00e9rie de processus de pilonnage ou d'\u00e9tirage \u00e0 froid. Le fait de travailler sur le tube tout en le refroidissant progressivement permet d'obtenir une plus grande r\u00e9sistance \u00e0 la traction. Il pr\u00e9sente \u00e9galement une surface plus fine et plus lisse.<\/span><\/p>\n

Cependant, les tubes sans soudure \u00e9tir\u00e9s \u00e0 froid sont plus chers que les tubes lamin\u00e9s \u00e0 chaud. Ils sont \u00e9galement plus exclusifs aux applications de haute pr\u00e9cision. Il s'agit notamment des syst\u00e8mes hydrauliques, de la construction automobile et des appareils \u00e0 pression.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
