Tubos soldados de aleaci\u00f3n de n\u00edquel<\/h1>\n \n

\n Cuando los proyectos industriales requieren transporte de fluidos de gran di\u00e1metro, conductos de escape extensos o soluciones rentables de intercambio de calor, los tubulares soldados son la mejor opci\u00f3n. 28Nickel fabrica tubos soldados de aleaci\u00f3n de n\u00edquel de alta calidad a partir de chapas y flejes laminados de primera calidad. Sometidos a radiograf\u00eda (X-Ray) 100% y a un riguroso control de calidad, nuestros productos soldados garantizan que el cord\u00f3n de soldadura tenga exactamente la misma resistencia a la corrosi\u00f3n y la misma resistencia mec\u00e1nica que la superaleaci\u00f3n base.\n <\/p>\n <\/div>\n\n

Calidades de aleaci\u00f3n disponibles para tubos soldados<\/h2>\n

\n Fabricamos sistemas de tuber\u00edas soldadas para todo tipo de aplicaciones, desde el agua de mar agresiva de las plantas desalinizadoras hasta los gases de combusti\u00f3n altamente \u00e1cidos de los depuradores de la generaci\u00f3n de energ\u00eda.\n <\/p>\n \n

Ventajas t\u00e9cnicas de la construcci\u00f3n soldada<\/h2>\n

\n Las tecnolog\u00edas avanzadas de soldadura continua (como GTAW\/TIG y Plasma) combinadas con el tratamiento t\u00e9rmico posterior a la soldadura han hecho que las soldaduras aleaciones de n\u00edquel<\/a> una alternativa muy fiable a los tubos sin soldadura.\n <\/p>\n \n

\n
\n
\u2b55<\/div>\n

Di\u00e1metros grandes ilimitados<\/h3>\n <\/div>\n

Mientras que los tubos sin soldadura est\u00e1n limitados por la capacidad de las prensas de extrusi\u00f3n (suelen tener un di\u00e1metro m\u00e1ximo de 24 pulgadas), los tubos soldados pueden laminarse y fabricarse con pr\u00e1cticamente cualquier di\u00e1metro, lo que los hace esenciales para grandes conductos qu\u00edmicos y de escape.<\/p>\n <\/div>\n\n

\n

Eficiencia en costes y plazos<\/h3>\n <\/div>\n

El conformado de tubos a partir de chapas planas o bobinas es mucho m\u00e1s r\u00e1pido y econ\u00f3mico que la perforaci\u00f3n de tochos macizos. Esto supone un importante ahorro de costes en proyectos de infraestructuras a gran escala que requieren kil\u00f3metros de tuber\u00edas.<\/p>\n <\/div>\n\n

\n
\n
\ud83d\udd0d<\/div>\n

100% Integridad de la soldadura<\/h3>\n <\/div>\n

Nuestros tubos soldados se someten a estrictos ensayos no destructivos (END), que incluyen radiograf\u00eda de rayos X 100% y pruebas hidrost\u00e1ticas. A menudo, el cord\u00f3n de soldadura se trabaja en fr\u00edo y se recuece completamente por disoluci\u00f3n para combinar a la perfecci\u00f3n su estructura metal\u00fargica con el metal base.<\/p>\n <\/div>\n\n

\n
\n
\ud83d\udccf<\/div>\n

Concentricidad superior<\/h3>\n <\/div>\n

Dado que se forman a partir de chapas planas de espesor muy uniforme, los tubos soldados presentan generalmente una mejor concentricidad y un espesor de pared (WT) m\u00e1s consistente que los tubos sin soldadura, que pueden sufrir una ligera excentricidad durante la extrusi\u00f3n.<\/p>\n <\/div>\n\n <\/div>\n\n

Tubos soldados de gran di\u00e1metro fabricados con aleaciones como Hastelloy C-276<\/a> y Inconel 625<\/a> son la columna vertebral de los sistemas de desulfuraci\u00f3n de gases de combusti\u00f3n (FGD), ya que manipulan lodos muy \u00e1cidos y abrasivos.<\/p>\n <\/div>\n\n

Los tramos largos de tuber\u00edas soldadas de Monel 400 se utilizan mucho en l\u00edneas de toma de agua de mar, calentadores de salmuera y sistemas de agua contra incendios de plataformas en alta mar debido a su excepcional resistencia a las picaduras de cloruro.<\/p>\n <\/div>\n\n
