Abstract
TUBO SEM EMENDAS E MÉTODO PARA FABRICAR O MESMO. Fornece-se um tubo sem emendas tendo excelente desempenho de resistência à pressão e um método para fabricar o mesmo. O tubo sem emendas no qual uma porção de parede fina em uma direção circunferencial de tubo é formada em uma direção axial do tubo, na qual um segmento de linha formado ao conectar uma extremidade e a outra extremidade da porção de parede fina ao longo de uma superfície de tubo com uma distância mais curta em uma direção de formação da porção de parede fina é inclinado em um ângulo a de 5,0° ou mais em relação à direção axial do tubo. É preferencial que uma extremidade e a outra extremidade da porção de parede fina sejam estabelecidas a partir de uma região em um tubo selecionado com um comprimento mais curto entre um comprimento de 1,0 m na direção axial do tubo e 90% de um comprimento na direção axial do tubo na qual a porção de parede fina se volta uma vez na direção circunferencial do tubo.
