Tube Fittings

Instrumentation Tube Fittings

As conexões para tubos de instrumentação Aptek são utilizadas para garantir uma vedação estanque e livre de torque em diversas conexões de tubulação de processos e instrumentação. Esses produtos eliminam vazamentos dispendiosos e perigosos.

Conforme ilustrado na figura, a conexão padrão para tubos é composta por quatro peças. Essas peças são usinadas de acordo com normas internacionais para assegurar alta qualidade. As anilhas passam por processos de endurecimento e polimento para garantir uma melhor fixação por compressão (swaging). As porcas recebem um banho de prata para evitar o travamento das roscas. Embora a conexão seja constituída por quatro peças, ao ser instalada no tubo…
