JISCO's Duplex Steel of\u00a0<\/strong>Petr\u00f3leo <\/strong>Faz outra grande conquista: entra no campo de alta tecnologia<\/strong><\/h2>\n

Alguns dias atr\u00e1s, junto com a opera\u00e7\u00e3o bem-sucedida de fundo de po\u00e7o de liga resistente \u00e0 corros\u00e3o enrolada 2205 tubos de a\u00e7o inoxid\u00e1vel<\/a> no campo petrol\u00edfero Changqing da China National Petroleum Corporation, marcou a entrada do a\u00e7o duplex JISCO 2205 de petr\u00f3leo no campo de alta tecnologia.<\/p>\n

\"Duplex

A corros\u00e3o \u00e9 um problema mundial que a ind\u00fastria petrol\u00edfera vem enfrentando. Na explora\u00e7\u00e3o de petr\u00f3leo e g\u00e1s, a corros\u00e3o de sulfeto de hidrog\u00eanio, di\u00f3xido de carbono, \u00edons cloreto e outros meios \u00e9 uma das raz\u00f5es importantes para a falha de tubula\u00e7\u00f5es. Cerca de um ter\u00e7o dos campos de petr\u00f3leo e g\u00e1s do mundo cont\u00e9m g\u00e1s sulfeto de hidrog\u00eanio. Os campos de Sichuan, Changqing, norte da China, Xinjiang e Jianghan s\u00e3o todos campos de petr\u00f3leo e g\u00e1s que cont\u00eam enxofre. A tubula\u00e7\u00e3o enrolada de a\u00e7o inoxid\u00e1vel 2205 resistente \u00e0 corros\u00e3o tem uma resist\u00eancia \u00e0 press\u00e3o interna e externa superior em mais de 30% \u00e0 do a\u00e7o carbono comum, o que \u00e9 especialmente adequado para ambientes de trabalho de alta corros\u00e3o. Com a ajuda da JISCO, a tubula\u00e7\u00e3o enrolada de alta liga forneceu novas op\u00e7\u00f5es para aumentar e estabilizar a produ\u00e7\u00e3o de po\u00e7os antigos contendo meios corrosivos como sulfeto de hidrog\u00eanio e di\u00f3xido de carbono no campo de g\u00e1s de Xiagu em Changqing Oilfield.<\/p>\n

\"A\u00e7o

\"A tubula\u00e7\u00e3o enrolada tem altas exig\u00eancias para a resist\u00eancia \u00e0 corros\u00e3o do a\u00e7o inoxid\u00e1vel, e s\u00e3o necess\u00e1rios testes ultra-s\u00f4nicos para cada metro, o que requer uma pureza de a\u00e7o muito alta\". Chen Xingrun, engenheiro respons\u00e1vel do ramo de a\u00e7o inoxid\u00e1vel da JISCO Hongxing Co., Ltd. apresentou: \"Austenita de tubo enrolado H\u00e1 inclus\u00f5es quebradi\u00e7as ao redor da interface de fase com ferrite, que causar\u00e3o soltura e rachaduras durante o processo de dobra do tubo, levando \u00e0 detec\u00e7\u00e3o inconsistente de falhas\".<\/p>\n

Enfrentando requisitos especiais, chin\u00eas fornecedor de acess\u00f3rios para tubos de a\u00e7o inoxid\u00e1vel<\/a> A JISCO desenvolveu uma tecnologia especial de controle de inclus\u00e3o para a\u00e7o inoxid\u00e1vel duplex 2205, que resolveu efetivamente este problema. \"A composi\u00e7\u00e3o de nosso a\u00e7o inoxid\u00e1vel duplex 2205 \u00e9 controlada com precis\u00e3o, e o equivalente de resist\u00eancia a furos \u00e9 est\u00e1vel acima de 35\". Os produtos foram inspecionados pelos clientes e todos s\u00e3o qualificados\". Chen Xingrun disse: \"Este ano, forneceremos mais de 100 toneladas de chapas de a\u00e7o inoxid\u00e1vel duplex n\u00ba 1 2205 que foram usadas para fazer tubos enrolados de \u00f3leo\".<\/p>\n
