Abstract
Una conexión roscada mejorada a ser cargada en una dirección axial, comprendiendo dicha conexión dos piezas (I) que tienen ejes de simetría coincidentes y (II) que tienen diferentes coeficientes de dilatación térmica lineal, en las cuales una pieza es una piez macho roscada y la otra pieza es una pieza hembra roscada. Caracterizada porque comprende proveer, a temperatura ambiente, una conicidad tal que el cambio en el huelgo radial por unidad de longitud entre las roscas opuestas de cada pieza es igual a la expresión A delta T zeta, en la cual: A = diferencia en los coeficientes de dilatación térmica lineal de los materiales en los cuales consiste cada pieza, en dirección axial; delta T = temperatura operativa de la conexión menos temperatura ambiente; y zeta = ángulo aguo formado por la cara cargada de la rosca de cualquiera de las piezas con los ejes de simetría aumentando dicho huelgo radial en dirección de la carga de la pieza que tiene el coeficiente más elevado de dilatación térmica.
