coude soud\u00e9 bout \u00e0 bout en acier inoxydable<\/figcaption><\/figure>\nLes d\u00e9fauts des raccords de tuyauterie soud\u00e9s bout \u00e0 bout sont \u00e9galement \u00e9vidents. Parce que le processus de soudage et le processus de moulage sont simples, les trous d'air, les soudures, les fissures, etc. sont faciles \u00e0 se produire et la pression est g\u00e9n\u00e9ralement moindre.<\/p>\n
Ci-dessous, nous nous concentrerons sur les d\u00e9fauts courants des raccords de tuyauterie soud\u00e9s et sur la fa\u00e7on d'\u00e9viter ces probl\u00e8mes.<\/em><\/p>\nLes d\u00e9fauts courants des raccords de tuyauterie soud\u00e9s bout \u00e0 bout sont sujets aux pores, aux fissures et aux soudures faibles. Les bulles sont dues au fait que le gaz br\u00fblant existe sous forme de bulles entre les interstices de soudage, qui sont g\u00e9n\u00e9ralement \u00e0 l'int\u00e9rieur. C'est difficile \u00e0 voir. Ce n'est que par inspection que vous pouvez le d\u00e9couvrir. La fa\u00e7on d'\u00e9viter est d'utiliser du carburant avec moins d'impuret\u00e9s, et l'autre est de nettoyer. Soudez l'apparence des plaques d'acier pour \u00e9liminer l'huile, le gaz et l'humidit\u00e9.<\/p>\n
La fissure fait r\u00e9f\u00e9rence \u00e0 la fissure caus\u00e9e par le sulfure entrant dans le m\u00e9tal fondu lors de la fabrication de tuyaux soud\u00e9s. La raison en est que la zone de s\u00e9gr\u00e9gation du soufre contient du sulfure de fer \u00e0 bas point de fusion et la pr\u00e9sence d'hydrog\u00e8ne dans l'acier. La mesure d'\u00e9vitement \u00e0 prendre est de nettoyer la surface de soudure. Et le nettoyage et le s\u00e9chage du flux.<\/p>\n
Le joint faible fait r\u00e9f\u00e9rence \u00e0 la possibilit\u00e9 d'un espace entre les deux plaques d'acier du tuyau soud\u00e9. Cela a un grand impact sur le tuyau soud\u00e9. La m\u00e9thode de d\u00e9tection la plus directe consiste \u00e0 supprimer l'eau d'essai pour voir s'il y a des fuites d'eau et \u00e9viter les mesures. C'est un bon moule, et les sp\u00e9cifications et les formes doivent \u00eatre faites conform\u00e9ment aux normes. Le joint soud\u00e9 est lisse et lisse, et il ne doit pas y avoir de rouille.<\/p>","protected":false},"featured_media":5217,"template":"","categories":[186],"tags":[],"class_list":["post-5559","blog","type-blog","status-publish","has-post-thumbnail","hentry","category-stainless-steel-knowledge"],"yoast_head":"\n
