Les vannes forg\u00e9es ont tendance \u00e0 \u00eatre meilleures pour les applications \u00e0 haute temp\u00e9rature et haute pression. Ces types de vannes sont moins sujets \u00e0 la fatigue thermique car les parois sont plus minces que celles en fonte. De plus, les options forg\u00e9es ont une masse plus \u00e9lev\u00e9e, ce qui les rend m\u00e9caniquement plus solides.\r\n\r\n\r\n\r\n\r\n\r\nCependant, il existe plusieurs raisons pour lesquelles un robinet \u00e0 tournant sph\u00e9rique forg\u00e9 n'est peut-\u00eatre pas le mieux adapt\u00e9 \u00e0 votre application. Premi\u00e8rement, le processus de forgeage cr\u00e9e des limites en termes de taille et de forme des vannes. Le forgeage fonctionne g\u00e9n\u00e9ralement mieux pour les vannes et les composants plus petits. De plus, tous les m\u00e9taux ne se pr\u00eatent pas au forgeage, ce qui limite vos options en mati\u00e8re de mat\u00e9riaux de vanne.\r\n\r\n\r\n\r\n\r\nAvantages et inconv\u00e9nients des vannes en fonte\r\n\r\n\r\n\r\n\r\nLes vannes coul\u00e9es sont une excellente option lorsque vous avez besoin de vannes \u00e0 d\u00e9lai d'ex\u00e9cution rapide et \u00e0 faible co\u00fbt, car leur production n\u00e9cessite moins de main d'\u0153uvre. En outre, le processus de moulage permet des formes et une fabrication de vannes plus complexes. Vous disposez \u00e9galement d\u2019une plus grande flexibilit\u00e9 dans le choix des mat\u00e9riaux, car de nombreux types de m\u00e9taux conviennent au moulage.\r\n\r\n\r\n\r\n\r\n\r\nBien que les vannes en fonte soient assez solides et durables lorsque vous choisissez un fabricant de haute qualit\u00e9, il existe n\u00e9anmoins certaines restrictions. Par exemple, le processus de solidification peut cr\u00e9er de petites impuret\u00e9s dans le m\u00e9tal.

GET DIFFERENCE BETWEEN CAST AND FORGED IRONS INFORMATION Advantages and Disadvantages of Forged Valves There are many reasons why you may want a forged ball valve for your application instead of a cast valve. Forged valves do tend to be better for high-temperature and high-pressure applications. These types of valves are less prone to thermal fatigue because the walls are thinner compared to cast alternatives. Also, forged options have a higher mass, making them mechanically stronger. However, there are a few reasons why a forged ball valve may not be best for your application. First, the forging process does create limitations for valve size and shape. Forging generally works better for smaller valves and components. In addition, not every metal is suitable for forging, which limits your options for valve material. Advantages and Disadvantages of Cast Valves Cast valves are a great option where you need quick turnaround and low-cost valves, as they require less labor to produce. Also, the casting process allows for more complex shapes and valve manufacturing. You also have greater flexibility in material choice, as many types of metals are suitable for casting. While cast valves are quite strong and durable when you choose a high-quality manufacturer, there are still some restrictions. For example, the solidification process can create small impurities in the metal. They also are less resistant to high temperatures and pressures compared to a forged ball valve.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/fr\/tag\/difference-between-cast-and-forged\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebSite\",\"@id\":\"https:\/\/zecovalve.com\/#website\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"ZECO Valve\",\"description\":\"Industrial Ball Valve, Gate Valve and Globe Valve Manufacturer\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":\"https:\/\/zecovalve.com\/?s={search_term_string}\",\"query-input\":\"required name=search_term_string\"}],\"inLanguage\":\"fr-FR\"},{\"@type\":\"CollectionPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-cast-and-forged#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/difference-between-cast-and-forged\",\"name\":\"Difference Between Cast and Forged Irons | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-cast-and-forged#breadcrumb\"},\"inLanguage\":\"fr-FR\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/difference-between-cast-and-forged\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-cast-and-forged#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"Home\"}},{\"@type\":\"ListItem\",\"position\":2,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-cast-and-forged\",\"url\":\"https:\/\/zecovalve.com\/tag\/difference-between-cast-and-forged\",\"name\":\"Difference Between Cast and Forged\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/tags\/3268","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/posts?tags=3268"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
