\"tubes<\/p>\n

Les tubes d'acier utilis\u00e9s dans les op\u00e9rations industrielles se r\u00e9partissent en deux cat\u00e9gories : les tubes sans soudure et les tubes avec soudure. Il est essentiel de comprendre leurs diff\u00e9rences pour d\u00e9terminer lequel est le mieux adapt\u00e9 \u00e0 vos besoins.<\/p>\n

Aper\u00e7u des tubes en acier sans soudure<\/h2>\n

\"tube<\/p>\n

Tubes sans soudure<\/em><\/a>\u00a0sont consid\u00e9r\u00e9s comme plus solides et plus fiables que les\u00a0tuyaux<\/em>\u00a0en raison de leur structure uniforme et de l'absence\u00a0de<\/em>\u00a0les soudures ou les joints.<\/p>\n

Comme leur nom l'indique, les tubes en acier sans soudure n'ont pas de joint de soudure. La mati\u00e8re premi\u00e8re principale pour la fabrication des tubes sans soudure est la billette d'acier. Les billettes sont perfor\u00e9es \u00e0 l'aide d'un outil de per\u00e7age, ce qui donne un tube d'acier sans joint. Ces tubes sont droits et ne pr\u00e9sentent pas de coins ou d'angles soud\u00e9s. Les tubes en acier sans soudure sont fabriqu\u00e9s par laminage \u00e0 chaud, laminage \u00e0 froid ou \u00e9tirage \u00e0 froid. Les tubes en acier sans soudure ont une excellente r\u00e9sistance \u00e0 la flexion et \u00e0 la torsion. C'est pourquoi ils sont utilis\u00e9s dans des applications \u00e0 haute pression. Ils composent les tuyaux des plates-formes p\u00e9troli\u00e8res, les arbres d'entra\u00eenement des automobiles, les usines chimiques et les structures de soutien \u00e0 la construction.<\/p>\n

 <\/p>\n

Vue d'ensemble des tubes d'acier soud\u00e9s<\/b><\/strong><\/h2>\n

\"tube<\/p>\n

Les tubes d'acier soud\u00e9s sont \u00e9galement appel\u00e9s tubes d'acier soud\u00e9s. Les bandes ou les plaques d'acier sont des mati\u00e8res premi\u00e8res primaires. Parce qu'ils sont g\u00e9n\u00e9ralement ronds et couramment utilis\u00e9s dans le transport de l'eau, du p\u00e9trole et du gaz, ils pr\u00e9sentent un joint de soudure longitudinal le long de leur corps. Ils pr\u00e9sentent un cordon de soudure longitudinal le long de leur corps. Avec le post-traitement, ce cordon est \u00e0 peine visible. Au cours de la fabrication, des rouleaux donnent une forme cylindrique aux plaques d'acier. Les extr\u00e9mit\u00e9s sont soud\u00e9es selon le proc\u00e9d\u00e9 ERW ou SAW. Le traitement post-soudage garantit que le tube est dimensionnellement correct et qu'il r\u00e9pond aux exigences de r\u00e9sistance. Les tubes en acier soud\u00e9s sont principalement utilis\u00e9s dans les canalisations d'eau, de p\u00e9trole, de gaz ou d'eaux us\u00e9es. Ils sont surtout utilis\u00e9s dans l'industrie de la construction.<\/p>\n

 <\/p>\n

Diff\u00e9rences entre les tubes d'acier sans soudure et les tubes d'acier soud\u00e9s<\/b><\/strong><\/h2>\n

 <\/p>\n

Processus de production<\/b><\/strong><\/h3>\n

Alors que les tubes sans soudure sont fabriqu\u00e9s par extrusion et laminage de billettes, les tubes avec soudure sont fabriqu\u00e9s en assemblant des t\u00f4les d'acier par soudage. En raison de leurs diff\u00e9rents processus de production, ils pr\u00e9sentent des caract\u00e9ristiques diff\u00e9rentes. Par exemple, les tubes en acier soud\u00e9s contiennent du silicium, du soufre et du mangan\u00e8se. Ces \u00e9l\u00e9ments augmentent les performances de la soudure. En revanche, ils sont absents des tubes en acier sans soudure. En outre, en raison du processus de production laborieux des tubes sans soudure, l'ASTM autorise des irr\u00e9gularit\u00e9s d'\u00e9paisseur de paroi plus importantes que pour les tubes soud\u00e9s.<\/p>\n

 <\/p>\n

Structure et performance<\/b><\/strong><\/h3>\n

En raison de la p\u00e9n\u00e9tration de l'outil en acier lors de la perforation des billettes, les tubes sans soudure pr\u00e9sentent une excentricit\u00e9 plus \u00e9lev\u00e9e. Les tubes en acier soud\u00e9s sont fabriqu\u00e9s \u00e0 partir de t\u00f4les d'acier \u00e9tir\u00e9es et lamin\u00e9es et offrent une plus grande pr\u00e9cision au niveau de l'\u00e9paisseur. Les tubes en acier sans soudure ont une plus grande r\u00e9sistance \u00e0 la traction que les tubes avec soudure, mais ils ne conviennent pas au soudage. Il est plus facile de produire des tubes sans soudure \u00e0 parois \u00e9paisses et des tubes soud\u00e9s \u00e0 parois minces.<\/p>\n

 <\/p>\n

Co\u00fbt et efficacit\u00e9<\/b><\/strong><\/h3>\n

La fabrication de tubes en acier sans soudure est plus difficile que celle de tubes en acier avec soudure. Comme ils sont fabriqu\u00e9s en une seule longueur, leur assemblage doit avoir une taille fixe et fonctionner lentement. Les tubes en acier sans soudure ont une \u00e9paisseur plus \u00e9lev\u00e9e que les tubes soud\u00e9s, ce qui augmente leur co\u00fbt et leur temps de production. En raison de ces facteurs, les tubes sans soudure co\u00fbtent deux fois plus cher que les tubes avec soudure.<\/p>\n

 <\/p>\n

Apparence et pr\u00e9cision<\/b><\/strong><\/h3>\n

L'une des principales diff\u00e9rences entre ces deux tuyaux est le cordon de soudure. Si vous examinez la paroi int\u00e9rieure d'un tube soud\u00e9, vous constaterez la pr\u00e9sence d'un cordon de soudure longitudinal. Il n'y en a pas dans le cas d'un tube en acier sans soudure. Les tubes sans soudure sont aussi g\u00e9n\u00e9ralement plus \u00e9pais et plus larges que les tubes avec soudure.<\/p>\n

 <\/p>\n

Environnement applicable<\/b><\/strong><\/h3>\n

Une fois que vous connaissez l'environnement dans lequel les tubes en acier doivent \u00eatre utilis\u00e9s, vous pouvez d\u00e9terminer la meilleure composition d'alliage. Toutefois, leurs performances ne sont pas tr\u00e8s diff\u00e9rentes. Les tubes en acier sans soudure ont g\u00e9n\u00e9ralement une \u00e9paisseur de paroi et un diam\u00e8tre ext\u00e9rieur plus importants. Cela les rend id\u00e9aux pour les r\u00e9seaux de canalisations de p\u00e9trole et de gaz. Ils servent de composants structurels dans les machines industrielles. Les tubes en acier sans soudure conviennent mieux aux applications \u00e0 basse pression. Ils sont extr\u00eamement polyvalents et conviennent aux canalisations comportant des angles et des coudes. C'est pourquoi ils sont utilis\u00e9s dans les canalisations domestiques, les usines chimiques, les installations de traitement des eaux, etc.<\/p>\n

 <\/p>\n

Conclusion<\/b><\/strong><\/h2>\n

Les diff\u00e9rentes propri\u00e9t\u00e9s des tubes en acier sans soudure et des tubes en acier soud\u00e9s d\u00e9terminent en grande partie leurs sc\u00e9narios d'application. Avant d'investir dans des tuyaux pour votre projet, vous devez garder \u00e0 l'esprit leurs qualit\u00e9s distinctes. Vous pr\u00e9voyez un syst\u00e8me d'approvisionnement en eau domestique ? Les tubes en acier soud\u00e9s vous conviendront parfaitement. Vous posez un gazoduc sur une \u00e9tendue de terrain ? Pensez aux tubes en acier sans soudure.
