Os flanges cegos de aço são um tipo de flange usado para selar a extremidade de um tubo ou válvula. Eles geralmente são feitos de aço e são projetados para serem aparafusados na extremidade de um tubo ou válvula. O flange cego é usado quando a extremidade de um tubo ou válvula precisa ser fechada, permanente ou temporariamente. Isso pode ser necessário por vários motivos, como manutenção, reparo ou teste. Flanges cegos de aço estão disponíveis em uma variedade de tamanhos, materiais e classificações de pressão para atender às necessidades de diferentes aplicações. Eles são comumente usados em ambientes industriais e comerciais, como petróleo e gás, instalações de tratamento petroquímico e de água.
