Abstract

Inventia se refera la un racord pentru tevi cu filet conic, care sînt folosite în special, în industria petroliera, si care, fiind supuse în timpul montajului si exploatarii la solicitari mecanice mari, suporta un numar relativ mare de înfasurari si trebuie sa asigure o etansare buna a interiorului tevilor fata de exterior. Racordul, conform inventiei, este caracterizat prin aceea ca fiecare din niste cepuri, si niste mufe cu care pot fi prevazute fiecare din tevi au unul din niste fileturi, care se extind subtiîndu-se în mod progresiv pîna în imediata apropiere a uneia din niste suprafete de forma tronconica, concave si, respectiv, a uneia din niste suprafete de forma tronconica, concexe, care ajung în contact în urma realizarii îmbinarii, menâinîndu-se astfel, prin întrepatrunderea fileturilor cu unghi închis o prindere radiala pîna în apropierea suprafetelor de forma tronconica, concave si, respectiv, convexe.
