Introduction<\/h2>\n

Il existe deux cat\u00e9gories de tubes carr\u00e9s en acier : les tubes sans soudure et les tubes soud\u00e9s. Ces tubes sont largement utilis\u00e9s dans les applications industrielles et structurelles. Leurs proc\u00e9d\u00e9s de fabrication sont tr\u00e8s diff\u00e9rents. Ils se distinguent \u00e9galement par leurs propri\u00e9t\u00e9s m\u00e9caniques et leur structure de co\u00fbts.<\/p>\n

Il est essentiel de tenir compte de la capacit\u00e9 de charge de ces tubes lors du choix du type de tube appropri\u00e9. Il est \u00e9galement important que les fabricants de machines prennent en compte la r\u00e9sistance \u00e0 la pression de ces tubes. Leur durabilit\u00e9 et l'efficacit\u00e9 de leur fabrication constituent \u00e9galement des enjeux majeurs.<\/p>\n

Processus de fabrication<\/h2>\n

Les billettes d'acier rond massif sont utilis\u00e9es dans la fabrication de\u00a0tubes carr\u00e9s sans soudure<\/b><\/strong>. Pour obtenir un tube creux, cette billette est chauff\u00e9e puis perc\u00e9e. Pour obtenir une section carr\u00e9e, le tube est form\u00e9 par laminage ou \u00e9tirage \u00e0 froid. Ce proc\u00e9d\u00e9 ne n\u00e9cessite aucun cordon de soudure. Ces tubes pr\u00e9sentent une \u00e9paisseur de paroi uniforme.<\/p>\n

Les bobines ou bandes d'acier sont utilis\u00e9es dans\u00a0tubes carr\u00e9s soud\u00e9s<\/b><\/strong>. Il est n\u00e9cessaire de former \u00e0 froid le mat\u00e9riau pour lui donner une forme rectangulaire. Ensuite, on utilise une m\u00e9thode de soudage \u00e0 haute fr\u00e9quence ou par r\u00e9sistance pour souder le mat\u00e9riau le long du joint.<\/p>\n

R\u00e9sum\u00e9 des avantages et des inconv\u00e9nients<\/h2>\n

Les avantages des tubes carr\u00e9s sans soudure et des tubes carr\u00e9s soud\u00e9s sont les suivants :<\/strong><\/p>\n

Les tubes carr\u00e9s sans soudure pr\u00e9sentent une excellente r\u00e9sistance m\u00e9canique. Ils offrent une meilleure fiabilit\u00e9 structurelle. Le risque de fissuration est tr\u00e8s faible sur ces tubes.<\/p>\n

Les tubes carr\u00e9s soud\u00e9s pr\u00e9sentent l'avantage d'\u00eatre disponibles dans une large gamme de dimensions. Ils offrent une bonne flexibilit\u00e9 de fabrication. Gr\u00e2ce \u00e0 un processus de fabrication plus rapide, leur co\u00fbt de production est faible.<\/p>\n

Les limites des tubes carr\u00e9s sans soudure et des tubes carr\u00e9s soud\u00e9s sont les suivantes :<\/strong><\/p>\n

Son cycle de fabrication est plus long. Les tubes carr\u00e9s sans soudure ont un co\u00fbt de production plus \u00e9lev\u00e9. Ce mat\u00e9riau n'est disponible qu'en tr\u00e8s grandes dimensions.<\/p>\n

Les tubes carr\u00e9s soud\u00e9s pr\u00e9sentent une faible r\u00e9sistance \u00e0 la pression. Leur cordon de soudure peut c\u00e9der sous l'effet de contraintes extr\u00eames. Il existe un risque de d\u00e9fauts dans les tubes lors du soudage, souvent dus \u00e0 une fabrication de mauvaise qualit\u00e9.<\/p>\n

Analyse des co\u00fbts<\/h2>\n

Le co\u00fbt est l'un des principaux facteurs d\u00e9terminants dans les achats industriels.<\/strong><\/p>\n

La production n\u00e9cessite le per\u00e7age de billettes, le laminage \u00e0 chaud, l'\u00e9tirage \u00e0 froid et plusieurs op\u00e9rations de finition. tubes carr\u00e9s sans soudure<\/strong>. Ces proc\u00e9d\u00e9s entra\u00eenent une complexit\u00e9 suppl\u00e9mentaire et une consommation d'\u00e9nergie accrue. La fabrication de tubes sans soudure est donc plus co\u00fbteuse que celle des tubes soud\u00e9s.<\/p>\n

L'utilisation de syst\u00e8mes de soudage automatis\u00e9s et de bandes d'acier am\u00e9liore l'efficacit\u00e9 de la production de tubes carr\u00e9s soud\u00e9s<\/strong>. Cela permettra de r\u00e9duire au minimum les co\u00fbts de main-d'\u0153uvre et le gaspillage de mat\u00e9riaux.<\/p>\n

Applications<\/h2>\n

Les tubes sans soudure peuvent \u00eatre utilis\u00e9s dans une vaste gamme de produits et de syst\u00e8mes. En raison de leur r\u00e9sistance \u00e0 la pression, la demande pour ces tubes dans les applications industrielles est tr\u00e8s forte. Les syst\u00e8mes p\u00e9troliers et gaziers ainsi que les \u00e9quipements hydrauliques utilisent largement ces tubes. On les retrouve \u00e9galement couramment dans les canalisations \u00e0 haute pression et les \u00e9changeurs de chaleur. L'ing\u00e9nierie structurelle et les machines porteuses privil\u00e9gient ces tubes.<\/p>\n

Les tubes soud\u00e9s sont utilis\u00e9s dans la fabrication de ch\u00e2ssis automobiles. Ils permettent \u00e9galement de r\u00e9aliser des constructions de b\u00e2timents et des structures m\u00e9talliques. Ils offrent de bonnes performances dans la fabrication de meubles. Ces tubes sont \u00e9galement privil\u00e9gi\u00e9s dans les projets de fabrication.<\/p>\n

Comment choisir entre des tubes carr\u00e9s sans soudure et des tubes carr\u00e9s soud\u00e9s<\/h2>\n

Les ing\u00e9nieurs doivent tenir compte des normes et sp\u00e9cifications du secteur lors du choix de ces tubes. Ils doivent \u00e9galement prendre en consid\u00e9ration la capacit\u00e9 de charge m\u00e9canique des tubes avant de les s\u00e9lectionner. Les caract\u00e9ristiques de l'environnement corrosif et le proc\u00e9d\u00e9 de fabrication constituent \u00e9galement des facteurs importants \u00e0 prendre en compte.<\/p>\n

Conclusion<\/h2>\n

Tout ce qui pr\u00e9c\u00e8de montre que les tubes carr\u00e9s sans soudure pr\u00e9sentent une r\u00e9sistance m\u00e9canique et une r\u00e9sistance \u00e0 la pression sup\u00e9rieures. En revanche, les tubes carr\u00e9s soud\u00e9s sont plus \u00e9conomiques. La flexibilit\u00e9 de production est bonne pour ces tubes.<\/p>\n

Le choix doit d\u00e9pendre des exigences du projet. Les conditions d'exploitation et le budget du projet constituent \u00e9galement des facteurs d\u00e9terminants.<\/p>","protected":false},"excerpt":{"rendered":"
