Abstract

"JUNçãO DE ROSCA E ELEMENTO DE PERFURAçãO DE ROCHA". A presente invenção se refere a uma junção de rosca de aço e a um elemento de perfuração para perfuração de percussão por meio do que água de descarga é utilizada, compreendendo seções de seções transversais reduzidas e pelo menos uma rosca externa substancialmente cilíndrica (14) bem como uma rosca interna substancialmente cilíndrica (12). A rosca externa (14) está proporcionada sobre um batoque (13) intencionado para constituir uma parte integral de um primeiro componente de fileira de perfuração (10). As roscas (12, 14) compreendem os flancos de rosca (16, 17; 18, 19) e as raízes de rosca (20; 21) proporcionadas entre os flancos. As raízes de rosca (20) da rosca externa cilíndrica (14) estão proporcionadas substancialmente distantes a partir das cristas associadas (22) da rosca interna cilíndrica (12). Pelo revestimento das raízes de rosca (20) da rosca externa cilíndrica (14) com pelo menos uma camada de um material de potencial de eletrodo mais baixo do que o do aço, a referida camada sendo feita a partir de metais como alumínio, zinco e magnésio ou ligas dos mesmos, uma duração de vida útil incrementada para a conexão rosqueada é obtida.
