Abstract
Patente de Invenção: "UNIãO DE TUBOS". A invenção refere-se a uma união de tubos, com um elemento de luva, que apresenta uma seção roscada interna, que se estende da extremidade axialmente para dentro, à qual se segue uma seção não roscada, e com um elemento de pino, que apresenta uma seção roscada formada de modo complementar ao elemento de luva, à qual se segue uma seção não roscada, que se estende até a extremidade frontal, também designada como lábio e as seções não roscadas entram em contato uma com a outra no estado aparafusado e formam um sistema de vedação metálico, sendo que o sistema de vedação está dotado de duas zonas de contato distanciadas uma da outra e das quais pelo menos uma zona de contato apresenta contornos de seção transversal geometricamente diferentes. A invenção está caracterizada pelo fato de que a zona de contato que apresenta uma distância menor da extremidade (5) do lábio (4) está formada como assento de proteção e a zona de contato que apresenta uma distância maior da extremidade (5) do lábio (4) está formada como assento de vedação, sendo que para o assento de vedação são escolhidos uma distância para a entrada de rosca e um grau da deformação por flexão (1), que produz para o assento de vedação uma pressão de superfície de pelo menos seis vezes a pressão de superfície teoricamente necessária, mas, no máximo, 90% do limite de alongamento, em relação ao material utilizado, sendo que o grau da deformação por flexão (1) é sempre maior do que a sobreposição de rosca na região da entrada de rosca e por entrada de rosca está definido um plano, no qual a rosca de pino e a de luva têm o primeiro contato no lado do lábio e que para o assento de proteção é escolhida uma distância da extremidade (5) do lábio (4), por um lado, e do assento de vedação, por outro lado, bem como um grau de deformação (1) 1,15 a 1,30 vezes mais alto em relação ao assento de vedação, que, na dependência do grau de deformação por flexão (1) escolhido do assento de vedação, produz uma tensão total no assento de vedação, mesmo levando em consideração tolerâncias de fabricação, bem como a sobreposição de cargas e momentos, que atuam externamente, depois do aparafusamento, sob conservação total da função de vedação, que é, no máximo igual ou menor do que o limite de elasticidade do material utilizado.Invention Patent: "TUBE UNION". The invention relates to a pipe joint, with a sleeve element, which has an internal threaded section, which extends from the end axially inward, to which a non-threaded section follows, and with a pin element, which it has a threaded section formed in a complementary way to the sleeve element, followed by a non-threaded section, which extends to the front end, also known as the lip and the non-threaded sections come into contact with each other in the screwed state and they form a metallic sealing system, the sealing system being provided with two contact zones distant from each other and of which at least one contact zone has geometrically different cross-sectional contours. The invention is characterized by the fact that the contact zone which has a shorter distance from the end (5) of the lip (4) is formed as a protective seat and the contact zone which has a greater distance from the end (5) of the lip (4) is formed as a sealing seat, and for the sealing seat, a distance for the thread entry and a degree of bending deformation are chosen (1), which produces a surface pressure of at least for the sealing seat. at least six times the theoretically necessary surface pressure, but at most 90% of the elongation limit, in relation to the material used, and the degree of flexion deformation (1) is always greater than the thread overlap in the region From the thread inlet and through the thread inlet, a plane is defined, in which the pin and glove threads have the first contact on the lip side and for the protection seat, a distance from the end is chosen. and (5) the lip (4), on the one hand, and the sealing seat, on the other hand, as well as a degree of deformation (1) 1.15 to 1.30 times higher in relation to the sealing seat, which, depending on the degree of bending deformation (1) chosen from the sealing seat, produces a total tension in the sealing seat, even taking into account manufacturing tolerances, as well as the overlapping of loads and moments, which act externally, afterwards of screwing, under total conservation of the sealing function, which is at most equal to or less than the elasticity limit of the material used.
