Abstract

UN METODO PARA PROTEGER ROSCAS DE TORNILLO CONJUGADAS CONTRA DAÑOS RECIPROCOS, AL MENOS BAJO PARES DE TORSION DE APRIETO, EN EL CUAL SE APLICA UN LUBRICANTE SECO, TAL COMO DISULFURO DE MOLIBDENO, A UNA DE LAS ROSCAS, Y SE APLICA UN LUBRICANTE LIQUIDO A LA OTRA ROSCA. DESPUES LAS ROSCAS SON APRETADAS HASTA EL VALOR DEL PAR DE TORSION REQUERIDO. CUANDO ESTAN COMPLETAMENTE EMPAREJADAS, EL PASO DE FUGA NO QUEDARA ENMASCARADO COMO CONSECUENCIA DE LA VOLATILIZACION DE CUALQUIERA DE LOS COMPONENTES DE CADA LUBRICANTE. EL INVENTO ES APLICABLE A ACOPLAMIENTOS DE OLEODUCTOS, GASODUCTOS Y OTRAS TUBERIAS.
