Les diff\u00e9rences entre les vari\u00e9t\u00e9s de tubes soud\u00e9s sont principalement dues \u00e0 la diversit\u00e9 de leurs proc\u00e9d\u00e9s de fabrication. Dans le paysage de la fabrication et du soudage des tuyaux, deux m\u00e9thodes de fabrication excellent - ERW et EFW, produisant des tuyaux soud\u00e9s. Tubes ERW<\/a> et EFW, respectivement.\u00a0<\/span><\/p>\n

Les deux m\u00e9thodes peuvent pr\u00eater \u00e0 confusion en raison de leurs noms similaires et de la soudure \u00e9lectrique impliqu\u00e9e dans les deux processus de fabrication. Cependant, elles sont diff\u00e9rentes \u00e0 bien des \u00e9gards.\u00a0<\/span><\/p>\n

Pour s\u00e9lectionner le bon tube pour vos projets d'ing\u00e9nierie et de structure, vous devez savoir comment diff\u00e9rencier les tubes ERW et EFW, car ils ont des sp\u00e9cifications diff\u00e9rentes.

Processus de fabrication des tubes ERW et EFW<\/h2>\n

\"Processus<\/p>\n

Processus de fabrication des tubes ERW<\/b><\/p>\n

Dans le proc\u00e9d\u00e9 ERW, les t\u00f4les ou les bandes de bobines sont form\u00e9es \u00e0 froid. En leur donnant une forme cylindrique, ces bandes sont ensuite soud\u00e9es par ERW (Electric Resistance Welding). Il s'agit de chauffer les bords des bandes m\u00e9talliques \u00e0 l'aide d'un courant \u00e9lectrique \u00e0 haute fr\u00e9quence (ou \u00e0 basse fr\u00e9quence). Ensuite, \u00e0 l'aide du rouleau presseur ou des matrices, elles sont assembl\u00e9es pour former Tubes ERW<\/a> avec des coutures longitudinales.<\/span><\/p>\n

Dans les applications modernes, le soudage par r\u00e9sistance \u00e9lectrique \u00e0 haute fr\u00e9quence est privil\u00e9gi\u00e9. Il permet d'obtenir des joints solides et durables sans utiliser de mat\u00e9riau d'apport. Bien qu'une utilisation \u00e0 basse fr\u00e9quence soit possible, plusieurs d\u00e9formations peuvent \u00eatre observ\u00e9es, notamment un collage inad\u00e9quat des soudures, des fissures en crochet et de la corrosion.<\/span><\/p>\n

Apr\u00e8s le soudage, les coutures ext\u00e9rieures peuvent \u00eatre coup\u00e9es pour les rendre ind\u00e9tectables. En m\u00eame temps, les coutures int\u00e9rieures sont laiss\u00e9es telles quelles.<\/span><\/p>\n

Processus de fabrication des tubes EFW<\/b><\/p>\n

Le proc\u00e9d\u00e9 EFW, \u00e9galement appel\u00e9 soudage \u00e0 l'arc ou par faisceau d'\u00e9lectrons, utilise un arc \u00e9lectrique pour faire fondre ou comprimer les bords m\u00e9talliques. Ils sont ensuite fusionn\u00e9s pour former des tubes EFW cylindriques avec un joint longitudinal, comme dans le proc\u00e9d\u00e9 ERW. Dans ce cas, la pressurisation n'est pas n\u00e9cessaire, car les bords sont fondus et fusionnent uniform\u00e9ment. Toutefois, l'EFW peut utiliser ou non des mat\u00e9riaux d'apport.<\/span><\/p>\n

          Dans quels domaines le tube ERW est-il utilis\u00e9 ?<\/h2>\n

          En tant que m\u00e9thode couramment utilis\u00e9e pour la fabrication de tubes soud\u00e9s, les tubes ERW sont largement utilis\u00e9s dans les applications de transport de m\u00e9dias. Les applications industrielles couvrent divers secteurs. Il s'agit notamment du chauffage, de la ventilation et de la climatisation, de la plomberie, du p\u00e9trole et du gaz, de l'industrie \u00e9nerg\u00e9tique, de l'a\u00e9rospatiale, de la lutte contre les incendies, etc.<\/span><\/p>\n

          Quelles sont les applications des tubes EFW ?<\/h2>\n

          L'EFW est une alternative \u00e9conomique \u00e0 la m\u00e9thode de fabrication des tubes par soudage. Elle permet de produire des tubes \u00e0 haute r\u00e9sistance m\u00e9canique et \u00e0 haute r\u00e9sistance \u00e0 la corrosion. Les tubes EFW sont utilis\u00e9s dans des applications \u00e0 haute pression qui n\u00e9cessitent des tol\u00e9rances serr\u00e9es. Les applications concernent des secteurs industriels tels que la chimie, l'agroalimentaire et la p\u00e9trochimie.<\/span><\/p>\n

          Conclusion<\/h2>\n

          Les tubes ERW et EFW sont tous deux des tubes soud\u00e9s et sont utilis\u00e9s dans divers secteurs industriels. Il est essentiel de comprendre les deux types de tubes les plus couramment utilis\u00e9s afin de garantir une s\u00e9lection ad\u00e9quate pour votre projet. Choisissez toujours le tube apr\u00e8s avoir \u00e9valu\u00e9 vos besoins. S\u00e9lectionnez-le en fonction des exigences sp\u00e9cifiques de l'application. Celles-ci comprennent la pression, le fluide transport\u00e9, la temp\u00e9rature et votre budget.\u00a0<\/span><\/p>","protected":false},"excerpt":{"rendered":"
