Abstract

Patente de Invenção: <B>"APARELHO PARA REDUZIR A TENSãO DE FLEXIONAMENTO DE PRENDEDOR EM CONEXõES COM FLANGES"<D> Um aparelho para reduzir a tensão de flexionamento conferida a prendedores rosqueados em conexões com flanges é descrito. O aparelho inclui uma arruela de redução de tensão posicionada entre a cabeça do prendedor rosqueado e um alargador na face posterior do flange. Em uma primeira modalidade, a arruela de redução de tensão utiliza uma superfície superior afunilada orientada com relação ao flange para compensar a flexão do flange quando o prendedor rosqueado é apertado a um valor de torque predeterminado. As segunda e terceira modalidades utilizando superfícies esféricas e cilíndricas são também mostradas, Uma quarta modalidade elimina a necessidade da arruela de redução de tensão e trabalha a superfície afunilada na face posterior do flange.
