Abstract

"MéTODO DE PRODUçãO DE UM TUBO SEM COSTURA". A presente invenção refere-se a produção de um tubo sem costura realizando-se as laminações de alongamento e de dimensionamento em um tubo matriz para formação de um tubo sem costura, a ocorrência de porções de variação de espessura no tubo sem costura é suprimida identificando-se previamente as porções de variação de espessura de parede onde a espessura varia na direção circunferencial do tubo sem costura, e realizando-se a laminação de alongamento de forma que a espessura das porções do tubo matriz correspondentes às porções da variação de espessura da parede do tubo sem costura são diferentes em espessura no término da laminação de alongamento daquela de outras porções do tubo matriz. Como resultado, as variações locais na espessura da parede na direção circunferencial de um tubo sem costura são evitadas.
