Diferenças entre tubos pretos e tubos galvanizados

Diferenças entre tubos pretos e tubos galvanizados

Dessa forma, quando uma peça passa por um processo de galvanização, a camada de zinco impede a oxidação do ferro, porque evita que ele entre em contato com o ar e com a água – ou seja, o processo de galvanização impede o ferrugem. Os tubos de aço retangulares também possuem alta aplicabilidade na produção de maquinário e equipamentos que exigem alta resistência e durabilidade. Devido o tubo de aço sem costura não passar por soldagem nenhuma, isso favorece a canalização de outros materiais tubos de aço que funcionam através de pressão. Já para os perfis de alumínio extrudados que são peças com acabamento mais requintado e resistência à corrosão a anodização é mais usada devido sua fixação ser de melhor qualidade. Ela é estável do ponto de vista químico, não se decompõe, não é tóxica e ainda é resistente à temperatura. A diversidade de acessórios prontos no mercado confere ao alumínio uma montagem mais rápida, sendo comparados ao brinquedo lego por sua forma de encaixe das estruturas.

Além disso, vale lembrar que o aço exige um tratamento mais elaborado, como pintura eletrostática ou capa plástica para evitar que o material sofra com a oxidação ao longo de tempo. O aço, por sua vez, é um material com carbono incorporado, muito mais robusto, pesado e resistente. A escolha do material adequado vai depender das especificações e das necessidades de cada tipo de obra ou projeto. O Metalon pode ainda ser pintado com esmalte sintético de qualquer cor.

O acabamento das pontas é o de fabricação, admitindo-se pequenas rebarbas. Atestado Os tubos podem ser fornecidos com ensaio elétrico não destrutivo ou teste hidrostático. Mediante pedido, os tubos podem ser fornecidos com certificado que atesta a análise química e as propriedades mecânicas. No entanto, em praticamente todo o mundo, esses aços apresentam custo pouco competitivo e têm sido raramente empregados. Pelos aspectos de leveza, versatilidade e facilidade de manutenção, esses tubos são aplicados com grande frequência em obras de grande porte, como estádios de futebol, complexos esportivos, aeroportos, plataformas de petróleo etc. Oferece resistência à compressão e à torção, por isso são considerados itens de estruturação de obras.

Esse tipo de tubo é muito usado na arquitetura e na construção civil, no emprego de estruturas metálicas de brinquedos de playgrounds, equipamentos para academias, corrimões de escadas, equipamentos médicos, usinagens, entre outros. As normas mais conhecidas e utilizadas para a fabricação dos Tubos de Aço Carbono são a ASTM , API , DIN (Alemã) e NBR . E as principais normas internacionais para tubos condutores de aço sem costura são API 5L, ASTM A-106, NBR-5590 e ASTM A-335. Os tubos são usados na construção dos equipamentos de academia, principalmente os redondos, que servem como barra.

Qual a diferença entre tubo e metalon?

Qual metalon não enferruja?

Os tubos de aço carbono, tanto tubos estruturais como tubos de condução, podem contar com acabamentos que lhe garantam uma proteção maior ao tempo. Um destes tipos de acabamento é conhecido como galvanização, e ele pode ser mais importante do que você imagina. Convém ressaltar também, que outra grande vantagem do tubo metalon quadrado é a disponibilidade. Por ser um material com demanda muito grande atualmente, utilizá-lo confere a segurança de que não faltará este elemento no projeto. A grande utilização e valorização deste produto ainda tem outra vantagem, a redução do custo. Estas bobinas são produzidas normalmente em espessuras variando 0,30 a 2,70 mm e largura entre 700 mm a 1.624 mm.

Dessa forma, pode-se encontrar no mercado tubos em aço carbono com 0,30% de aço carbono, com 0,60%, ou ainda com 1,00%. Pensando em como é importante saber as diferenças entre ambos os modelos, no artigo de hoje você irá conhecer mais sobre esses tubos, de modo a ficar por dentro também de suas características, vantagens e particularidades. O ramo industrial tem utilizado cada vez mais o tubo de aço por conta das novas aplicações do produto. O fato de ser um material de aço carbono, anticorrosivo e antioxidante, garante durabilidade de até 10 anos, além de que, quando galvanizado, não sofre o risco de ficar enferrujado.

Alumínio

O armazenamento ou acesso técnico que é usado exclusivamente para fins estatísticos. Fabricamos diversos produtos com tecnologia avançada e qualidade máxima. Seja numa aplicação doméstica, comercial ou industrial, vale a pena passar um tempo a mais pesquisando e escolhendo uma matéria-prima que melhor vai se adequar às necessidades da obra ou do cliente. Já que ambos os tubos são feitos de aço, eles podem ser combinados nos trabalhos de canalização, desde que o revestimento seja removido no local de junção. O vendedor precisa saber quais são as medidas dos lados e da espessura do metalon em milímetros. Dessa maneira, o material pode ser higienizado utilizando apenas água e algum produto de limpeza de preferência.

Na hora de comprar ou encomendar uma solução para o seu negócio é importante saber que alguns materiais se adequam melhor a um determinado uso do que outros. Para encontrar todas essas características no tubo metalon, é necessário contar com uma empresa qualificada que realiza o desenvolvimento desse tipo de material. Ah, e essa resistência natural ainda tem a chance de ser aumentada com a aplicação de uma fina camada de óxido de alumínio – além de proteger o material, isso gera um acabamento mais bonito para o visual da sua obra. Já em relação à oxidação e corrosão, o material tende a ser menos resistente quando comparado com o alumínio. O aço sempre vai exigir um tratamento de pintura eletrostática ou capa plástica, por exemplo – se não houver, ele vai oxidar rapidamente. E como o aço requer solda para sua montagem, ele obtém uma maior resistência mecânica quando comparado ao alumínio.

Galvalume ou Galvanizada: Qual Telha Metálica é Melhor?

A galvanização é um processo complexo e que deve ser feito seguindo normas de pesos e medidas, pois é utilizada como prevenção para que os tubos não sofram com o processo de ferrugem e oxidação. Esse processo garante que o material tenha a qualidade necessária para ser utilizado em instalações hidráulicas. As tubulações podem ser feitas de diferentes materiais, cada um deles é desenhado e feito para diferentes tipos de uso. Isso porque certos tipos de materiais são utilizados em tubulações que passam por grandes níveis de estresse, seja por causa da pressão ou da corrosão. Entre os dois principais tipos de tubulações estão o tubo galvanizado e o tubo preto.
