Abstract

Un método para fabricar curvatubos revestidos, en donde el tubo más pequeno y más delgado se inserta en el tubo más grande y más grueso; ambas extremidades del ensamblaje de tubo se sellan mediante soldadura y el espacio cerrado se llena con nitrogeno. El gas se coloca luego bajo presion, y una porcion del ensamblaje de tubo se calienta por medio de un dispositivo de induccion de calor hasta alcanzar una temperatura apropiada para permitir una buena capacidad de deformacion del metal. Luego se aplica un momento flector al tiempo que se mantiene la presion interna neumática controlada en el interior del ensamblaje de tubo.A method for manufacturing coated tube bends, where the smallest and thinnest tube is inserted into the larger and thicker tube; both ends of the tube assembly are sealed by welding and the closed space is filled with nitrogen. The gas is then placed under pressure, and a portion of the tube assembly is heated by means of a heat induction device until an appropriate temperature is reached to allow a good deformability of the metal. A bending moment is then applied while maintaining the controlled pneumatic internal pressure inside the tube assembly.
