Abstract

"JUNTA ROSCADA PARA TUBOS". A presente invenção refere-se a uma junta roscada que confere, de um modo económico, propriedades de vedação a uma parte de metal a metal, e que impede o desenvolvimento de escoriação no momento da formação, compreende um tubo de aço 1 tendo uma rosca macho 1b e uma superfície de vedação não-roscada 1 a, e um acoplamento 2 tendo em sua superfície interna uma rosca fêmea 2b e uma superfície de vedação não-roscada 2 a. Com a pressão limite na superfície interna do tubo sendo Py, (l)a pressão média Pm da parte de contato anular satisfaz Pm/Py <242> 3 e a largura na direção axial da parte que recebe uma pressão Ps que satisfaz Ps/Py <242> 1 na parte de contato anular é pelo menos 1 mm (ou pelo menos 2 mm), e a aspereza de superfície Ry de ambas as superfícies de vedação não-roscadas é no máximo 25 <109>m (ou no máximo 30 <109>m), ou (2) a relação entre a pressão média Pm da parte de contato anular e a aspereza Ry (<109>m)da superfície de vedação não-roscada satisfaz Pm/Py <242> 0,0032 x RY^ 2^ + 1,0, e a largura na direção axial da parte que recebe uma pressão Ps que satisfaz Ps/Py <242> 1 na parte de contato anular é pelo menos 1 mn.
