Abstract

TUBO METáLICO E MéTODO DE FABRICAçãO DO MESMO. A presente invenção refere-se a um tubo metálico de acordo com a invenção que possui uma pluralidade de saliéncias que possuem alturas diferentes, se estendem na direção axial, e são dispostas na direção circunferencial em sua superfície circunferencial interna. Se o número Reynolds mudar e a estrutura de estria e a escala de um vértice tipo grampo de cabelo mudarem, a estria e o vértice tipo grampo de cabelo podem combinar, cada um, com qualquer uma das saliências. Portanto, a fricção de fluido pode ser reduzida em uma ampla faixa de número Reynolds.
