Tubos soldados de liga de n\u00edquel<\/h1>\n \n

\n Quando os projectos industriais requerem o transporte de fluidos de grande di\u00e2metro, condutas de exaust\u00e3o extensas ou solu\u00e7\u00f5es de troca de calor rent\u00e1veis, os tubos soldados s\u00e3o a primeira escolha. A 28Nickel fabrica tubos soldados de liga de n\u00edquel de alta qualidade a partir de chapas e tiras laminadas de primeira qualidade. Submetidos a radiografia 100% (Raio-X) e a um controlo de qualidade rigoroso, os nossos produtos soldados asseguram que o cord\u00e3o de soldadura funciona exatamente com a mesma resist\u00eancia \u00e0 corros\u00e3o e for\u00e7a mec\u00e2nica que a superliga de base.\n <\/p>\n <\/div>\n\n

Graus de liga dispon\u00edveis para tubos soldados<\/h2>\n

\n Fabricamos sistemas de tubagem soldados para lidar com tudo, desde \u00e1gua do mar agressiva em instala\u00e7\u00f5es de dessaliniza\u00e7\u00e3o at\u00e9 gases de combust\u00e3o altamente \u00e1cidos em depuradores de gera\u00e7\u00e3o de energia.\n <\/p>\n \n

Vantagens de engenharia da constru\u00e7\u00e3o soldada<\/h2>\n

\n As tecnologias avan\u00e7adas de soldadura cont\u00ednua (como GTAW\/TIG e Plasma) combinadas com o tratamento t\u00e9rmico p\u00f3s-soldadura tornaram a soldadura ligas de n\u00edquel<\/a> uma alternativa altamente fi\u00e1vel aos tubos sem costura.\n <\/p>\n \n

Grandes di\u00e2metros ilimitados<\/h3>\n <\/div>\n

Enquanto os tubos sem costura s\u00e3o limitados pelas capacidades das prensas de extrus\u00e3o (normalmente com cerca de 24 polegadas), os tubos soldados podem ser laminados e fabricados com praticamente qualquer di\u00e2metro, o que os torna essenciais para grandes condutas de produtos qu\u00edmicos e condutas de exaust\u00e3o.<\/p>\n <\/div>\n\n

Efici\u00eancia em termos de custos e prazos de entrega<\/h3>\n <\/div>\n

Formar tubos a partir de chapas ou bobinas planas prontamente dispon\u00edveis \u00e9 significativamente mais r\u00e1pido e mais econ\u00f3mico do que perfurar biletes s\u00f3lidos. Isto proporciona grandes poupan\u00e7as de custos para projectos de infra-estruturas de grande escala que requerem quil\u00f3metros de tubagem.<\/p>\n <\/div>\n\n

100% Integridade da soldadura<\/h3>\n <\/div>\n

Os nossos tubos soldados s\u00e3o submetidos a rigorosos testes n\u00e3o destrutivos (NDT), incluindo radiografia de raios X 100% e testes hidrost\u00e1ticos. O cord\u00e3o de soldadura \u00e9 frequentemente trabalhado a frio e totalmente recozido em solu\u00e7\u00e3o para combinar perfeitamente a sua estrutura metal\u00fargica com o metal de base.<\/p>\n <\/div>\n\n

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

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

Uma vez que s\u00e3o formados a partir de chapas planas com uma espessura altamente uniforme, os tubos soldados apresentam geralmente uma melhor concentricidade e uma espessura de parede (WT) mais consistente do que os tubos sem costura, que podem sofrer de uma ligeira excentricidade durante a extrus\u00e3o.<\/p>\n <\/div>\n\n <\/div>\n\n
