Abstract

Un tubo metálico que tiene una porción extrema engrosada, el tubo metálico incluye: cuando se ve en una dirección longitudinal del tubo metálico, una porción delgada que tiene un espesor t0; una primera porción engrosada que está provista en un extremo y tiene un espesor T que es mayor que el espesor t0; y una primera porción cónica o ahusada que está dispuesta entre la porción delgada y la primera porción engrosada y tiene el espesor que aumenta gradualmente desde t0 hasta T; cuando se mide una dureza de una superficie interior de la primera porción engrosada en una dirección circunferencial y la dureza se traza con respecto a una posición en la dirección circunferencial, en la que una forma de onda que representa una porción de alta dureza que tiene una dureza que es del 95% o más de una dureza máxima en la dirección circunferencial y una forma de onda que representa una porción de dureza baja que tiene una dureza que es menor que 95% de la dureza máxima aparecen alternativamente, y aparecen una pluralidad de combinaciones de la forma de onda que representa la porción de alta dureza y la forma de onda que representa la porción de baja dureza.
