Abstract

tubo para soldagem do espelho para fabricação de reator de ebulição vertical com passo tubo reduzido. passo tubo reduzido dentro de um reator de troca de calor de casco e tubo como, por exemplo, um reator de eo, é fornecido utilizando um material de soldagem que tem uma alta tração (isto é, uma resistência à tração superior a 600 mpa). passo tubo reduzido permite que tubos mais alongados (os tubos são preenchidos com um catalisador) estejam presentes em um reator e, portanto, um reator menor pode ser fabricado. notavelmente, o uso de um material de soldagem de alta resistência à tração permite a implementação de uma pequena ranhura de soldagem localizada entre uma parede lateral chanfrada de uma porção superior chanfrada de uma abertura fornecida em um material de revestimento do espelho (que está localizado no topo de um espelho) e uma parede lateral mais externa do tubo alongado passando pela abertura no material de revestimento do espelho.
