{"id":118,"count":3,"description":"La cat\u00e9gorie pompes et vannes couvre les composants en titane et en m\u00e9taux r\u00e9sistants \u00e0 la corrosion utilis\u00e9s dans le traitement chimique, le service en eau de mer, la manutention de saumure, les \u00e9quipements \u00e9lectrochimiques et le contr\u00f4le industriel des fluides. Les produits peuvent inclure des vannes en titane, des vannes \u00e0 bille en titane, des pompes en titane, des corps de vanne, des pi\u00e8ces de pompe, des roues, des arbres et des composants sur plan lorsque la compatibilit\u00e9 des mat\u00e9riaux est importante. Les demandes de prix devraient pr\u00e9ciser le fluide, la concentration, la temp\u00e9rature, la pression, la norme de raccordement, l'exigence d'\u00e9tanch\u00e9it\u00e9, le plan ou la r\u00e9f\u00e9rence du mod\u00e8le, la nuance du mat\u00e9riau et l'\u00e9tendue du contr\u00f4le. Pour les pi\u00e8ces de remplacement de pompe ou de vanne, les photos, dimensions et d\u00e9tails du plan d'origine aident \u00e0 confirmer l'ajustement, la sur\u00e9paisseur de corrosion, les exigences d'usinage et la protection d'emballage des surfaces d'\u00e9tanch\u00e9it\u00e9 ou usin\u00e9es. Si la pi\u00e8ce est expos\u00e9e \u00e0 une suspension, une solution de chlorure ou un service acide, la condition de service devrait \u00eatre indiqu\u00e9e avant la finalisation du choix de la nuance. Pour les ensembles de r\u00e9gulation du d\u00e9bit en eau de mer, saumure ou service chimique, voir vannes en titane<\/a> les options pour les demandes de prix sur plan. Les pages associ\u00e9es de r\u00e9gulation du d\u00e9bit incluent pompe centrifuge en titane<\/a>, vannes en titane<\/a>, vanne \u00e0 bille en titane<\/a> et soufflantes en titane<\/a> pour les projets de manutention de fluides et de gaz corrosifs.\n\n

D\u00e9tails des sp\u00e9cifications avec sources<\/h2>\n

ASME B16.34 constitue la base pression-temp\u00e9rature des vannes, classant les conceptions \u00e0 extr\u00e9mit\u00e9s \u00e0 brides, filet\u00e9es et soud\u00e9es dans les classes standard de 150 \u00e0 4500, et les corps en titane relevant de ces classes sont g\u00e9n\u00e9ralement moul\u00e9s selon ASTM B367, dont les nuances comprennent C-2, C-3 et C-5, C-2 correspondant \u00e0 la composition chimique du Grade 2 corroy\u00e9. Les composants internes corroy\u00e9s rel\u00e8vent de num\u00e9ros diff\u00e9rents, ASTM B348 pour les barres de tige et d'arbre et ASTM B381 pour les corps et chapeaux forg\u00e9s, de sorte qu'une seule vanne peut l\u00e9gitimement porter trois d\u00e9signations mati\u00e8re ASTM ainsi qu'une classe B16.34.<\/p>\n

Beiyu fournit la partie corroy\u00e9e des ensembles de pompes et de vannes \u00e0 partir de sa gamme document\u00e9e : barre pour tiges et arbres de 1 \u00e0 500 mm de diam\u00e8tre dans des longueurs jusqu'\u00e0 6000 mm avec une tol\u00e9rance maintenue de h6 \u00e0 h9 selon la commande, plaque de 0.5 \u00e0 70 mm pour les plaques d'usure et d'\u00e9tanch\u00e9it\u00e9, et tube sans soudure de 5 \u00e0 325 mm de diam\u00e8tre ext\u00e9rieur pour les colonnes et les manchons. Au cours des 15 ann\u00e9es d'exp\u00e9rience de Penn dans l'exportation de titane, la garniture de remplacement est la demande qui arrive le plus souvent sans le certificat mati\u00e8re d'origine, Beiyu demande donc le fluide de service et la temp\u00e9rature de fonctionnement avant de s\u00e9lectionner l'une des quatre nuances qu'il propose le plus souvent pour les pi\u00e8ces en contact avec le fluide, Grade 2, Grade 5, Grade 7 et Grade 12, et exp\u00e9die le mat\u00e9riau s\u00e9lectionn\u00e9 avec MTC et EN 10204 3.1 selon le p\u00e9rim\u00e8tre de la commande sous tra\u00e7abilit\u00e9 par num\u00e9ro de coul\u00e9e.<\/p>","link":"https:\/\/beiyutitanium.com\/fr\/product-category\/metal-alloy\/pump-and-valve\/","name":"Pompe et vanne","slug":"pump-and-valve","taxonomy":"product_cat","parent":114,"meta":{"_templately_pack_id":"","_templately_imported_at":"","_templately_source":"","_templately_import_session_id":""},"menu_order":0,"yoast_head":"\nTitanium Pump & Valve Components | Corrosion-Resistant | Beiyu<\/title>\n<meta name=\"description\" content=\"Titanium valves, pumps and components in Gr2\/5\/7\/12 for chemical, seawater and brine service.
