Abstract

ENTALHES PARA A REDUçãO DE TENSãO PARA CONEXãO TUBULAR E PROCESSO DE LIBERAçãO DE TENSãO Entalhe para redução de tensão para conexões tubulares que relaciona-se a uma conexão rosqueada de cano, e inclui um membro de encaixe, um membro de pino, e um entalhe contínuo formado na rosca de um dos membros. O membro de encaixe apresenta uma rosca em formato de sambladura genérico, interna, afunilada com flancos de estoque, flancos de carga, raízes, e cristas. A rosca interna apresenta um início e um final e aumenta em largura em uma direção. O membro de pino também apresenta uma rosca em formato genérico de sambladura, externa, afunilada com flancos de estoque, flancos de carga, raízes e cristas. A rosca externa aumenta em largura na oura direção de modo que os flancos complementares das roscas respectivas movam-se em engate durante a montagem rotacional da conexão e formem superfícies de vedação que resistam ao escoamento de fluidos entre as rosas mediante montagem rotacional da conexão. Uma seção de uma das roscas internas e externas apresenta um entalhe contínuo formado nas raízes das mesmas. O entalhe estende-se a partir tanto do início ou do final de uma das roscas, reduzindo assim a pressão que se desenvolve entre as superfícies de vedação durante a montagem rotacional no lubrificante de rosca aplicado às roscas.
