Methods and coupled connections for tubes

A threaded pipe connection (60), comprising: a coupling body (62) having mating threads (70,74) formed internally, first and second pins (64,66) formed at the ends of a first and second tubular joint paratubos respectively first and second threads on the pins (72,68) formed respectively along the superficiesexternas of said first and second pins (64,66), said first being and second threads of espigasadaptadas to match the threads of said coupling to form a connection structural joint ysellado pressure between said first and second pins and said coupling, characterized by I dichocuerpo coupling is made from an element standard coupling, said first and second pins (64,66) having first and second faces of annular pin (76,78) respectively formed along the axial end surfaces the axial ends of said pins, each of the faces of pin a radial thickness defined between the inner diameter and the outer diameter dela tubular spigot on which is formed, said first being and second faces shank adapted paraconectarse one to another in the axial midpoint of said coupling approximately when said first- and second pins coincide exactly with said coupling, said coupling having no highlight any untwisting splicing said first and second pins on said first and second pins (64,66) are formed first and second pin ends (80,82), respectively, a first yuna second lengths of pin tips extending axially outwardly of pin faces corresponding respectively not being said tips of at least structurally espigasconectadas in part to said internal coupling threads when said first- and second pins coi fully nciden with said coupling whereby axial forces in said acoplamientoen adjacent radial locations at any of said tips tenon are not transmitted directly challenged coupling and said tip shank and a thread geometry with sides of negative charge on the threads of said first and second pins and matching lasroscas coupling, whereby said first and second pins and said coupling seimponen a compression forces in a radial direction after splicing of said faces of the ends of espigadurante the application of torque formation said connection.
