Abstract

EN UN METODO PARA EL DOBLADO DE TUBOS, GENERALMENTE DEFORMABLES O DOBLABLES CON APLICACION DE CALOR, EN EL QUE EL TUBO A DOBLAR PUEDE SER CALENTADO, SE APLICA UN APOYO INTERIOR Y, POSTERIORMENTE, SE PROCEDE AL DOBLADO. ANTES DEL PROCESO DE DOBLADO SE INTRODUCE UN TUBULAR EXPANDIBLE HASTA UNA DETERMINADA MEDIDA (3) EN EL TUBO A DOBLAR (1) Y EL TUBULAR INTERIOR (3) SE RELLENA DE UN FLUIDO SOMETIDO A PRESION, DE FORMA QUE SE ADAPTE TOTALMENTE A LA SUPERFICIE INTERIOR DEL TUBO A DOBLAR (1), A CONTINUACION SE PROCEDE AL PROCESO DE DOBLADO. LA HERRAMIENTA PARA LA REALIZACION DEL PROCESO COMPRENDE UN TUBULAR DE PRESION (3) PARA SER INTRODUCIDO, DE UN MATERIAL EXPANDIBLE BAJO PRESION, A CUYOS EXTREMOS SE ENCUENTRAN VALVULAS DE CERRAMIENTO (5, 6), CUYO DIAMETRO NO SERA SUPERIOR AL INTERIOR DEL TUBO A DOBLAR (12).
