Abstract

Método para realizar hidráulicamente el recalcado por expansión de un tubo en un agujero de una placa de tubos, en el cual un mandril hidráulico de expansión se introduce en el tubo en la zona situada en el agujero, se introduce un fluido en el espacio de presión anular definido radialmente entre el núcleo del mandril y dicho tubo y definido axialmente por las juntas de estanqueidad de las extremidades opuestas del mandril, y se aumenta la presión del fluido hasta un valor inferior predeterminado, estando dicho método caracterizado porque se aplica a continuación un breve impulso de presión al fluido para aumentar la presión del fluido en el espacio de presión anular durante un periodo de tiempo muy corto hasta un valor más elevado igual por lo menos al doble de dicho valor predeterminado antes de aflojar finalmente la presión en dicho espacio anular y retirar dicho mandril.
